| Summary: OpenSSH AuthorizedKeysCommand helpers | |
SSH (Secure Shell) is a program for logging into and executing commands on a remote machine. It replaces rsh (rlogin and rsh) and provides secure encrypted communication between two untrusted hosts over an insecure network. xorg-x11 (X Window System) connections and arbitrary TCP/IP ports can also be forwarded over the secure channel. This package contains helper applications for OpenSSH which retrieve keys from various sources.

- Update to openssh 9.9p1:
= Future deprecation notice
* OpenSSH plans to remove support for the DSA signature algorithm
in early 2025. This release disables DSA by default at compile
time. DSA, as specified in the SSHv2 protocol, is inherently
weak - being limited to a 160 bit private key and use of the
SHA1 digest. Its estimated security level is only 80 bits
symmetric equivalent.
OpenSSH has disabled DSA keys by default since 2015 but has
retained run-time optional support for them. DSA was the only
mandatory-to-implement algorithm in the SSHv2 RFCs, mostly
because alternative algorithms were encumbered by patents when
the SSHv2 protocol was specified.
This has not been the case for decades at this point and better
algorithms are well supported by all actively-maintained SSH
implementations. We do not consider the costs of maintaining
DSA in OpenSSH to be justified and hope that removing it from
OpenSSH can accelerate its wider deprecation in supporting
cryptography libraries.
= Potentially-incompatible changes
* ssh(1): remove support for pre-authentication compression.
OpenSSH has only supported post-authentication compression in
the server for some years. Compression before authentication
significantly increases the attack surface of SSH servers and
risks creating oracles that reveal information about
information sent during authentication.
* ssh(1), sshd(8): processing of the arguments to the "Match"
configuration directive now follows more shell-like rules for
quoted strings, including allowing nested quotes and \-escaped
characters. If configurations contained workarounds for the
previous simplistic quote handling then they may need to be
adjusted. If this is the case, it's most likely to be in the
arguments to a "Match exec" confition. In this case, moving the
command to be evaluated from the Match line to an external
shell script is easiest way to preserve compatibility with both
the old and new versions.
= New features
* ssh(1), sshd(8): add support for a new hybrid post-quantum key
exchange based on the FIPS 203 Module-Lattice Key Enapsulation
mechanism (ML-KEM) combined with X25519 ECDH as described by
https://datatracker.ietf.org/doc/html/draft-kampanakis-curdle-ssh-pq-ke-03
This algorithm "mlkem768x25519-sha256" is available by default.
* ssh(1): the ssh_config "Include" directive can now expand
environment as well as the same set of %-tokens "Match Exec"
supports.
* sshd(8): add a sshd_config "RefuseConnection" option that, if
set will terminate the connection at the first authentication
request.
* sshd(8): add a "refuseconnection" penalty class to sshd_config
PerSourcePenalties that is applied when a connection is dropped
by the new RefuseConnection keyword.
* sshd(8): add a "Match invalid-user" predicate to sshd_config
Match options that matches when the target username is not
valid on the server.
* ssh(1), sshd(8): update the Streamlined NTRUPrime code to a
substantially faster implementation.
* ssh(1), sshd(8): the hybrid Streamlined NTRUPrime/X25519 key
exchange algorithm now has an IANA-assigned name in addition to
the "@openssh.com" vendor extension name. This algorithm is now
also available under this name "sntrup761x25519-sha512"
* ssh(1), sshd(8), ssh-agent(1): prevent private keys from being
included in core dump files for most of their lifespans. This
is in addition to pre-existing controls in ssh-agent(1) and
sshd(8) that prevented coredumps. This feature is supported on
OpenBSD, Linux and FreeBSD.
* All: convert key handling to use the libcrypto EVP_PKEY API,
with the exception of DSA.
* sshd(8): add a random amount of jitter (up to 4 seconds) to the
grace login time to make its expiry unpredictable.
= Bugfixes
* sshd(8): relax absolute path requirement back to what it was
prior to OpenSSH 9.8, which incorrectly required that sshd was
started with an absolute path in inetd mode. bz3717
* sshd(8): fix regression introduced in openssh-9.8 that swapped
the order of source and destination addresses in some sshd log
messages.
* sshd(8): do not apply authorized_keys options when signature
verification fails. Prevents more restrictive key options being
incorrectly applied to subsequent keys in authorized_keys.
bz3733
* ssh-keygen(1): include pathname in some of ssh-keygen's
passphrase prompts. Helps the user know what's going on when
ssh-keygen is invoked via other tools. Requested in GHPR503
* ssh(1), ssh-add(1): make parsing user@host consistently look
for the last '@' in the string rather than the first. This
makes it possible to more consistently use usernames that
contain '@' characters.
* ssh(1), sshd(8): be more strict in parsing key type names. Only
allow short names (e.g "rsa") in user-interface code and
require full SSH protocol names (e.g. "ssh-rsa") everywhere
else. bz3725
* regress: many performance and correctness improvements to the
re-keying regression test.
* ssh-keygen(1): clarify that ed25519 is the default key type
generated and clarify that rsa-sha2-512 is the default
signature scheme when RSA is in use. GHPR505
* sshd(8): fix minor memory leak in Subsystem option parsing;
GHPR515
* All: additional hardening and consistency checks for the sshbuf
code.
* sshd(8): reduce default logingrace penalty to ensure that a
single forgotton login that times out will be below the penalty
threshold.
* ssh(1): fix proxy multiplexing (-O proxy) bug. If a mux started
with ControlPersist then later has a forwarding added using mux
proxy connection and the forwarding was used, then when the mux
proxy session terminated, the mux master process would issue a
bad message that terminated the connection.
= Portability
* sync contrib/ssh-copy-id to the latest upstream version.
* regress: improve portablility for some awk(1) usage
(e.g. Solaris)
* In the contrib/redhat RPM spec file, without_openssl was
previously incorrectly enabled unconditionally.
* sshd(8) restore audit call before exit that regressed in
openssh-9.8. Fixes an issue where the SSH_CONNECTION_ABANDON
event was not recorded.
* sshd(8): add support for class-imposed loging restrictions on
FreeBSD. Allowing auth_hostok(3) and auth_timeok(3) to control
logins.
* Build fixes for Musl libc.
* Fix detection of setres*id on GNU/Hurd
- Drop patches that were already merged by upstream:
* fix-memleak-in-process_server_config_line_depth.patch
* fix-audit-fail-attempt.patch
- Rebase patch with significant changes:
* openssh-8.1p1-audit.patch
- Rebase patches with context or trivial changes:
* openssh-7.7p1-fips.patch
* openssh-8.0p1-gssapi-keyex.patch
* openssh-9.6p1-crypto-policies-man.patch
* openssh-mitigate-lingering-secrets.patch
- Several spec file fixes so the package builds and can be
installed in SLE 15 SP5 and SLE 12 SP5
- Use gcc11 when building in SLE12 and SLE15.
* Thu Sep 12 2024 alarrosa@suse.com
- Drop most of openssh-6.6p1-keycat.patch (actually, it was just
commented out). The keycat binary isn't really installed nor
supported, so we can drop it, except for the code that is used
by other SELinux patches, which is what I kept from that patch
(boo#1229072).
- Add patch submitted to upstream to fix RFC4256 implementation
so that keyboard-interactive authentication method can send
instructions and sshd shows them to users even before a prompt
is requested. This fixes MFA push notifications (boo#1229010).
* 0001-auth-pam-Immediately-report-instructions-to-clients-and-fix-handling-in-ssh-client.patch
* Fri Aug 23 2024 alarrosa@suse.com
- Add patch to fix sshd not logging in the audit failed login
attempts (submitted to upstream in
https://github.com/openssh/openssh-portable/pull/516):
* fix-audit-fail-attempt.patch
- Use --enable-dsa-keys when building openssh. It's required if
the user sets the crypto-policy mode to LEGACY, where DSA keys
should be allowed. The option was added by upstream in 9.7 and
set to disabled by default.
- These two changes fix 2 of the 3 issues reported in bsc#1229650.
* Mon Aug 12 2024 alarrosa@suse.com
- Fix a dbus connection leaked in the logind patch that was
missing a sd_bus_unref call (found by Matthias Gerstner):
* logind_set_tty.patch
- Add a patch that fixes a small memory leak when parsing the
subsystem configuration option:
* fix-memleak-in-process_server_config_line_depth.patch
* Thu Aug 01 2024 alarrosa@suse.com
- Update to openssh 9.8p1:
= Security
* 1) Race condition in sshd(8) (bsc#1226642, CVE-2024-6387).
A critical vulnerability in sshd(8) was present in Portable
OpenSSH versions between 8.5p1 and 9.7p1 (inclusive) that may
allow arbitrary code execution with root privileges.
Successful exploitation has been demonstrated on 32-bit
Linux/glibc systems with ASLR. Under lab conditions, the attack
requires on average 6-8 hours of continuous connections up to
the maximum the server will accept. Exploitation on 64-bit
systems is believed to be possible but has not been
demonstrated at this time. It's likely that these attacks will
be improved upon.
Exploitation on non-glibc systems is conceivable but has not
been examined. Systems that lack ASLR or users of downstream
Linux distributions that have modified OpenSSH to disable
per-connection ASLR re-randomisation (yes - this is a thing, no
- we don't understand why) may potentially have an easier path
to exploitation. OpenBSD is not vulnerable.
We thank the Qualys Security Advisory Team for discovering,
reporting and demonstrating exploitability of this problem, and
for providing detailed feedback on additional mitigation
measures.
* 2) Logic error in ssh(1) ObscureKeystrokeTiming (bsc#1227318,
CVE-2024-39894).
In OpenSSH version 9.5 through 9.7 (inclusive), when connected
to an OpenSSH server version 9.5 or later, a logic error in the
ssh(1) ObscureKeystrokeTiming feature (on by default) rendered
this feature ineffective - a passive observer could still
detect which network packets contained real keystrokes when the
countermeasure was active because both fake and real keystroke
packets were being sent unconditionally.
This bug was found by Philippos Giavridis and also
independently by Jacky Wei En Kung, Daniel Hugenroth and
Alastair Beresford of the University of Cambridge Computer Lab.
Worse, the unconditional sending of both fake and real
keystroke packets broke another long-standing timing attack
mitigation. Since OpenSSH 2.9.9 sshd(8) has sent fake keystoke
echo packets for traffic received on TTYs in echo-off mode,
such as when entering a password into su(8) or sudo(8). This
bug rendered these fake keystroke echoes ineffective and could
allow a passive observer of a SSH session to once again detect
when echo was off and obtain fairly limited timing information
about keystrokes in this situation (20ms granularity by
default).
This additional implication of the bug was identified by
Jacky Wei En Kung, Daniel Hugenroth and Alastair Beresford and
we thank them for their detailed analysis.
This bug does not affect connections when
ObscureKeystrokeTiming was disabled or sessions where no TTY
was requested.
= Future deprecation notice
* OpenSSH plans to remove support for the DSA signature algorithm
in early 2025. This release disables DSA by default at compile
time.
DSA, as specified in the SSHv2 protocol, is inherently weak -
being limited to a 160 bit private key and use of the SHA1
digest. Its estimated security level is only 80 bits symmetric
equivalent.
OpenSSH has disabled DSA keys by default since 2015 but has
retained run-time optional support for them. DSA was the only
mandatory-to-implement algorithm in the SSHv2 RFCs, mostly
because alternative algorithms were encumbered by patents when

This has not been the case for decades at this point and better
algorithms are well supported by all actively-maintained SSH
implementations. We do not consider the costs of maintaining
DSA in OpenSSH to be justified and hope that removing it from
OpenSSH can accelerate its wider deprecation in supporting
cryptography libraries.
This release, and its deactivation of DSA by default at
compile-time, marks the second step in our timeline to finally
deprecate DSA. The final step of removing DSA support entirely
is planned for the first OpenSSH release of 2025.
DSA support may be re-enabled in OpenBSD by setting
"DSAKEY=yes" in Makefile.inc. To enable DSA support in
portable OpenSSH, pass the "--enable-dsa-keys" option to
configure.
= Potentially-incompatible changes
* all: as mentioned above, the DSA signature algorithm is now
disabled at compile time.
* sshd(8): the server will now block client addresses that
repeatedly fail authentication, repeatedly connect without ever
completing authentication or that crash the server. See the
discussion of PerSourcePenalties below for more information.
Operators of servers that accept connections from many users,
or servers that accept connections from addresses behind NAT or
proxies may need to consider these settings.
* sshd(8): the server has been split into a listener binary,
sshd(8), and a per-session binary "sshd-session". This allows
for a much smaller listener binary, as it no longer needs to
support the SSH protocol. As part of this work, support for
disabling privilege separation (which previously required code
changes to disable) and disabling re-execution of sshd(8) has
been removed. Further separation of sshd-session into
additional, minimal binaries is planned for the future.
* sshd(8): several log messages have changed. In particular, some
log messages will be tagged with as originating from a process
named "sshd-session" rather than "sshd".
* ssh-keyscan(1): this tool previously emitted comment lines
containing the hostname and SSH protocol banner to standard
error. This release now emits them to standard output, but adds
a new "-q" flag to silence them altogether.
* sshd(8): (portable OpenSSH only) sshd will no longer use
argv[0] as the PAM service name. A new "PAMServiceName"
sshd_config(5) directive allows selecting the service name at
runtime. This defaults to "sshd". bz2101
* (portable OpenSSH only) Automatically-generated files, such as
configure, config.h.in, etc will now be checked in to the
portable OpenSSH git release branch (e.g. V_9_8). This should
ensure that the contents of the signed release branch exactly
match the contents of the signed release tarball.
= New features
* sshd(8): as described above, sshd(8) will now penalise client
addresses that, for various reasons, do not successfully
complete authentication. This feature is controlled by a new
sshd_config(5) PerSourcePenalties option and is on by default.
sshd(8) will now identify situations where the session did not
authenticate as expected. These conditions include when the
client repeatedly attempted authentication unsucessfully
(possibly indicating an attack against one or more accounts,
e.g. password guessing), or when client behaviour caused sshd
to crash (possibly indicating attempts to exploit bugs in
sshd).
When such a condition is observed, sshd will record a penalty
of some duration (e.g. 30 seconds) against the client's
address. If this time is above a minimum configurable
threshold, then all connections from the client address will be
refused (along with any others in the same
PerSourceNetBlockSize CIDR range) until the penalty expire.
Repeated offenses by the same client address will accrue
greater penalties, up to a configurable maximum. Address ranges
may be fully exempted from penalties, e.g. to guarantee access
from a set of trusted management addresses, using the new
sshd_config(5) PerSourcePenaltyExemptList option.
We hope these options will make it significantly more difficult
for attackers to find accounts with weak/guessable passwords or
exploit bugs in sshd(8) itself. This option is enabled by
default.
* ssh(8): allow the HostkeyAlgorithms directive to disable the
implicit fallback from certificate host key to plain host keys.
= Bugfixes
* misc: fix a number of inaccuracies in the PROTOCOL.*
documentation files. GHPR430 GHPR487
* all: switch to strtonum(3) for more robust integer parsing in
most places.
* ssh(1), sshd(8): correctly restore sigprocmask around ppoll()
* ssh-keysign(8): stricter validation of messaging socket fd
GHPR492
* sftp(1): flush stdout after writing "sftp>" prompt when not
using editline. GHPR480
* sftp-server(8): fix home-directory extension implementation,
it previously always returned the current user's home directory
contrary to the spec. GHPR477
* ssh-keyscan(1): do not close stdin to prevent error messages
when stdin is read multiple times. E.g.
echo localhost | ssh-keyscan -f - -f -
* regression tests: fix rekey test that was testing the same KEX
algorithm repeatedly instead of testing all of them. bz3692
* ssh_config(5), sshd_config(5): clarify the KEXAlgorithms
directive documentation, especially around what is supported
vs available. bz3701.
= Portability
* sshd(8): expose SSH_AUTH_INFO_0 always to PAM auth modules
unconditionally. The previous behaviour was to expose it only
when particular authentication methods were in use.
* build: fix OpenSSL ED25519 support detection. An incorrect
function signature in configure.ac previously prevented
enabling the recently added support for ED25519 private keys in
PEM PKCS8 format.
* ssh(1), ssh-agent(8): allow the presence of the WAYLAND_DISPLAY
environment variable to enable SSH_ASKPASS, similarly to the
X11 DISPLAY environment variable. GHPR479
* build: improve detection of the -fzero-call-used-regs compiler
flag. bz3673.
* build: relax OpenSSL version check to accept all OpenSSL 3.x
versions.
* sshd(8): add support for notifying systemd on server listen and
reload, using a standalone implementation that doesn't depend
on libsystemd. bz2641
- Update to openssh 9.7p1:
= New features
* ssh(1), sshd(8): add a "global" ChannelTimeout type that
watches all open channels and will close all open channels if
there is no traffic on any of them for the specified interval.
This is in addition to the existing per-channel timeouts added
recently.
This supports situations like having both session and x11
forwarding channels open where one may be idle for an extended
period but the other is actively used. The global timeout could
close both channels when both have been idle for too long.
* All: make DSA key support compile-time optional, defaulting to
on.
= Bugfixes
* sshd(8): don't append an unnecessary space to the end of
subsystem arguments (bz3667)
* ssh(1): fix the multiplexing "channel proxy" mode, broken when
keystroke timing obfuscation was added. (GHPR#463)
* ssh(1), sshd(8): fix spurious configuration parsing errors when
options that accept array arguments are overridden (bz3657).
* ssh-agent(1): fix potential spin in signal handler (bz3670)
* Many fixes to manual pages and other documentation, including
GHPR#462, GHPR#454, GHPR#442 and GHPR#441.
* Greatly improve interop testing against PuTTY.
= Portability
* Improve the error message when the autoconf OpenSSL header
check fails (bz#3668)
* Improve detection of broken toolchain -fzero-call-used-regs
support (bz3645).
* Fix regress/misc/fuzz-harness fuzzers and make them compile
without warnings when using clang16

openssh-7.7p1-cavstest-kdf.patch where it belongs:
* fix-missing-lz.patch
* Mon Jul 15 2024 alarrosa@suse.com
- Add sshd.socket and sshd@.service units as alternative to the
sshd.service that makes systemd listen to the ssh port
and run sshd per incoming connection. To enable this,
disable sshd.service and enable sshd.socket . If you want to
use a non standard sshd port with sshd.socket you can do
"systemctl edit sshd.socket" and add something like:
[Socket]
ListenStream=8022
which listens on port 8022 as well as on port 22. If you want
to reset the list of listened ports and just use 8022, use:
[Socket]
ListenStream=
ListenStream=8022
- To enable a vsock listener in sshd (which allows to connect to
libvirt VMs), the systemd-experimental package needs to be
installed in the guest system, the libvirt-ssh-proxy package
needs to be installed in the host and the vm needs to have
vsock support (in virt-manager, click in "Add hardware" and
add "VSOCK VirtIO").
* Fri Jul 05 2024 alarrosa@suse.com
- Add patch from upstream to fix proxy multiplexing mode:
* 0001-upstream-fix-proxy-multiplexing-mode_-broken-when-keystroke.patch
- Add patch from upstream to restore correctly sigprocmask
* 0001-upstream-correctly-restore-sigprocmask-around-ppoll.patch
- Add patch from upstream to fix a logic error in
ObscureKeystrokeTiming that rendered this feature ineffective,
allowing a passive observer to detect which network packets
contained real keystrokes (bsc#1227318, CVE-2024-39894):
* 0001-upstream-when-sending-ObscureKeystrokeTiming-chaff-packets_.patch
* Wed Jul 03 2024 alarrosa@suse.com
- Add obsoletes for openssh-server-config-rootlogin since that
package existed for a brief period of time during SLE 15 SP6/
Leap 15.6 development but even if it was removed from the
repositories before GM, some users might have it in their
systems from having tried a beta/RC release (boo#1227350).
* Mon Jul 01 2024 alarrosa@suse.com
- Add patch to fix a race condition in a signal handler by removing
the async-signal-unsafe code (CVE-2024-6387, bsc#1226642):
* fix-CVE-2024-6387.patch
* Mon Jun 10 2024 alarrosa@suse.com
- Add #include <stdlib.h> in some files added by the ldap patch to
fix build with gcc14 (boo#1225904).
* openssh-7.7p1-ldap.patch
* Fri May 17 2024 alarrosa@suse.com
- Remove the recommendation for openssh-server-config-rootlogin
from openssh-server. Since the default for that config option
was changed in SLE it's not needed anymore in SLE nor in TW
(boo#1224392).
* Tue May 14 2024 alarrosa@suse.com
- Add a warning in %post of openssh-clients, openssh-server and
openssh-server-config-disallow-rootlogin to warn the user if
the /etc/ssh/(ssh_config.d|sshd_config.d) directories are not
being used (bsc#1223486).
* Mon May 13 2024 alarrosa@suse.com
- Only for SLE15, restore the patch file removed in
Thu Feb 18 13:54:44 UTC 2021 to restore the previous behaviour
from SP5 of having root password login allowed by default
(fixes bsc#1223486, related to bsc#1173067):
* openssh-7.7p1-allow_root_password_login.patch
- Since the default value for this config option is now set to
permit root to use password logins in SLE15, the
openssh-server-config-rootlogin subpackage isn't useful there so
we now create an openssh-server-config-disallow-rootlogin
subpackage that sets the configuration the other way around
than openssh-server-config-rootlogin.
* Mon Apr 15 2024 meissner@suse.com
- openssh-8.0p1-gssapi-keyex.patch: Added missing struct initializer,
added missing parameter (bsc#1222840)
* Fri Apr 12 2024 alarrosa@suse.com
- Make openssh-server recommend the openssh-server-config-rootlogin

- Update to openssh 9.6p1:
= Security
* ssh(1), sshd(8): implement protocol extensions to thwart the
so-called "Terrapin attack" discovered by Fabian Bäumer, Marcus
Brinkmann and Jörg Schwenk. This attack allows a MITM to effect a
limited break of the integrity of the early encrypted SSH transport
protocol by sending extra messages prior to the commencement of
encryption, and deleting an equal number of consecutive messages
immediately after encryption starts. A peer SSH client/server
would not be able to detect that messages were deleted
(bsc#1217950, CVE-2023-48795).
* ssh-agent(1): when adding PKCS#11-hosted private keys while
specifying destination constraints, if the PKCS#11 token returned
multiple keys then only the first key had the constraints applied.
Use of regular private keys, FIDO tokens and unconstrained keys
are unaffected.
* ssh(1): if an invalid user or hostname that contained shell
metacharacters was passed to ssh(1), and a ProxyCommand,
LocalCommand directive or "match exec" predicate referenced the
user or hostname via %u, %h or similar expansion token, then
an attacker who could supply arbitrary user/hostnames to ssh(1)
could potentially perform command injection depending on what
quoting was present in the user-supplied ssh_config(5) directive
(bsc#1218215, CVE-2023-51385).
= Potentially incompatible changes
* ssh(1), sshd(8): the RFC4254 connection/channels protocol provides
a TCP-like window mechanism that limits the amount of data that
can be sent without acceptance from the peer. In cases where this
limit was exceeded by a non-conforming peer SSH implementation,
ssh(1)/sshd(8) previously discarded the extra data. From OpenSSH
9.6, ssh(1)/sshd(8) will now terminate the connection if a peer
exceeds the window limit by more than a small grace factor. This
change should have no effect of SSH implementations that follow
the specification.
= New features
* ssh(1): add a %j token that expands to the configured ProxyJump
hostname (or the empty string if this option is not being used)
that can be used in a number of ssh_config(5) keywords. bz3610
* ssh(1): add ChannelTimeout support to the client, mirroring the
same option in the server and allowing ssh(1) to terminate
quiescent channels.
* ssh(1), sshd(8), ssh-add(1), ssh-keygen(1): add support for
reading ED25519 private keys in PEM PKCS8 format. Previously
only the OpenSSH private key format was supported.
* ssh(1), sshd(8): introduce a protocol extension to allow
renegotiation of acceptable signature algorithms for public key
authentication after the server has learned the username being
used for authentication. This allows varying sshd_config(5)
PubkeyAcceptedAlgorithms in a "Match user" block.
* ssh-add(1), ssh-agent(1): add an agent protocol extension to allow
specifying certificates when loading PKCS#11 keys. This allows the
use of certificates backed by PKCS#11 private keys in all OpenSSH
tools that support ssh-agent(1). Previously only ssh(1) supported
this use-case.
= Bugfixes
* ssh(1): when deciding whether to enable the keystroke timing
obfuscation, enable it only if a channel with a TTY is active.
* ssh(1): switch mainloop from poll(3) to ppoll(3) and mask signals
before checking flags set in signal handler. Avoids potential
race condition between signaling ssh to exit and polling. bz3531
* ssh(1): when connecting to a destination with both the
AddressFamily and CanonicalizeHostname directives in use,
the AddressFamily directive could be ignored. bz5326
* sftp(1): correct handling of the limits@openssh.com option when
the server returned an unexpected message.
* A number of fixes to the PuTTY and Dropbear regress/integration
tests.
* ssh(1): release GSS OIDs only at end of authentication, avoiding
unnecessary init/cleanup cycles. bz2982
* ssh_config(5): mention "none" is a valid argument to IdentityFile
in the manual. bz3080
* scp(1): improved debugging for paths from the server rejected for
not matching the client's glob(3) pattern in old SCP/RCP protocol
mode.
* ssh-agent(1): refuse signing operations on destination-constrained
keys if a previous session-bind operation has failed. This may
prevent a fail-open situation in future if a user uses a mismatched
ssh(1) client and ssh-agent(1) where the client supports a key type
that the agent does not support.
- Update to openssh 9.5p1:
= Potentially incompatible changes
* ssh-keygen(1): generate Ed25519 keys by default. Ed25519 public keys
are very convenient due to their small size. Ed25519 keys are
specified in RFC 8709 and OpenSSH has supported them since version 6.5
(January 2014).
* sshd(8): the Subsystem directive now accurately preserves quoting of
subsystem commands and arguments. This may change behaviour for exotic
configurations, but the most common subsystem configuration
(sftp-server) is unlikely to be affected.
= New features
* ssh(1): add keystroke timing obfuscation to the client. This attempts
to hide inter-keystroke timings by sending interactive traffic at
fixed intervals (default: every 20ms) when there is only a small
amount of data being sent. It also sends fake "chaff" keystrokes for
a random interval after the last real keystroke. These are
controlled by a new ssh_config ObscureKeystrokeTiming keyword.
* ssh(1), sshd(8): Introduce a transport-level ping facility. This adds
a pair of SSH transport protocol messages SSH2_MSG_PING/PONG to
implement a ping capability. These messages use numbers in the "local
extensions" number space and are advertised using a "ping@openssh.com"
ext-info message with a string version number of "0".
* sshd(8): allow override of Subsystem directives in sshd Match blocks.
= Bugfixes
* scp(1): fix scp in SFTP mode recursive upload and download of
directories that contain symlinks to other directories. In scp mode,
the links would be followed, but in SFTP mode they were not. bz3611
* ssh-keygen(1): handle cr+lf (instead of just cr) line endings in
sshsig signature files.
* ssh(1): interactive mode for ControlPersist sessions if they
originally requested a tty.
* sshd(8): make PerSourceMaxStartups first-match-wins
* sshd(8): limit artificial login delay to a reasonable maximum (5s)
and don't delay at all for the "none" authentication mechanism.
bz3602
* sshd(8): Log errors in kex_exchange_identification() with level
verbose instead of error to reduce preauth log spam. All of those
get logged with a more generic error message by sshpkt_fatal().
* sshd(8): correct math for ClientAliveInterval that caused the probes
to be sent less frequently than configured.
* ssh(1): fix regression in OpenSSH 9.4 (mux.c r1.99) that caused
multiplexed sessions to ignore SIGINT under some circumstances.
- Update to openssh 9.4p1:
= Potentially incompatible changes
* This release removes support for older versions of libcrypto.
OpenSSH now requires LibreSSL >= 3.1.0 or OpenSSL >= 1.1.1.
Note that these versions are already deprecated by their upstream
vendors.
* ssh-agent(1): PKCS#11 modules must now be specified by their full
paths. Previously dlopen(3) could search for them in system
library directories.
= New features
* ssh(1): allow forwarding Unix Domain sockets via ssh -W.
* ssh(1): add support for configuration tags to ssh(1).
This adds a ssh_config(5) "Tag" directive and corresponding
"Match tag" predicate that may be used to select blocks of
configuration similar to the pf.conf(5) keywords of the same
name.
* ssh(1): add a "match localnetwork" predicate. This allows matching
on the addresses of available network interfaces and may be used to
vary the effective client configuration based on network location.
* ssh(1), sshd(8), ssh-keygen(1): infrastructure support for KRL
extensions. This defines wire formats for optional KRL extensions
and implements parsing of the new submessages. No actual extensions
are supported at this point.
* sshd(8): AuthorizedPrincipalsCommand and AuthorizedKeysCommand now
accept two additional %-expansion sequences: %D which expands to
the routing domain of the connected session and %C which expands
to the addresses and port numbers for the source and destination
of the connection.
* ssh-keygen(1): increase the default work factor (rounds) for the
bcrypt KDF used to derive symmetric encryption keys for passphrase
protected key files by 50%.
= Bugfixes
* ssh-agent(1): improve isolation between loaded PKCS#11 modules
by running separate ssh-pkcs11-helpers for each loaded provider.
* ssh(1): make -f (fork after authentication) work correctly with
multiplexed connections, including ControlPersist. bz3589 bz3589
* ssh(1): make ConnectTimeout apply to multiplexing sockets and not
just to network connections.
* ssh-agent(1), ssh(1): improve defences against invalid PKCS#11
modules being loaded by checking that the requested module
contains the required symbol before loading it.
* sshd(8): fix AuthorizedPrincipalsCommand when AuthorizedKeysCommand
appears before it in sshd_config. Since OpenSSH 8.7 the
AuthorizedPrincipalsCommand directive was incorrectly ignored in
this situation. bz3574
* sshd(8), ssh(1), ssh-keygen(1): remove vestigal support for KRL
signatures When the KRL format was originally defined, it included
support for signing of KRL objects. However, the code to sign KRLs
and verify KRL signatues was never completed in OpenSSH. This
release removes the partially-implemented code to verify KRLs.
All OpenSSH tools now ignore KRL_SECTION_SIGNATURE sections in
KRL files.
* All: fix a number of memory leaks and unreachable/harmless integer
overflows.
* ssh-agent(1), ssh(1): don't truncate strings logged from PKCS#11
modules; GHPR406
* sshd(8), ssh(1): better validate CASignatureAlgorithms in
ssh_config and sshd_config. Previously this directive would accept
certificate algorithm names, but these were unusable in practice as
OpenSSH does not support CA chains. bz3577
* ssh(1): make `ssh -Q CASignatureAlgorithms` only list signature
algorithms that are valid for CA signing. Previous behaviour was
to list all signing algorithms, including certificate algorithms.
* ssh-keyscan(1): gracefully handle systems where rlimits or the
maximum number of open files is larger than INT_MAX; bz3581
* ssh-keygen(1): fix "no comment" not showing on when running
`ssh-keygen -l` on multiple keys where one has a comment and other
following keys do not. bz3580
* scp(1), sftp(1): adjust ftruncate() logic to handle servers that
reorder requests. Previously, if the server reordered requests then
the resultant file would be erroneously truncated.
* ssh(1): don't incorrectly disable hostname canonicalization when
CanonicalizeHostname=yes and ProxyJump was expicitly set to
"none". bz3567
* scp(1): when copying local->remote, check that the source file
exists before opening an SFTP connection to the server. Based on

- Update to openssh 9.3p2:
Security
========
Fix a condition where specific libaries loaded via
ssh-agent(1)'s PKCS#11 support could be abused to achieve remote
code execution via a forwarded agent socket if the following
conditions are met (bsc#1213504, CVE-2023-38408):
* Exploitation requires the presence of specific libraries on
the victim system.
* Remote exploitation requires that the agent was forwarded
to an attacker-controlled system.
Exploitation can also be prevented by starting ssh-agent(1) with an
empty PKCS#11/FIDO allowlist (ssh-agent -P '') or by configuring
an allowlist that contains only specific provider libraries.
This vulnerability was discovered and demonstrated to be exploitable
by the Qualys Security Advisory team.
In addition to removing the main precondition for exploitation,
this release removes the ability for remote ssh-agent(1) clients
to load PKCS#11 modules by default (see below).
Potentially-incompatible changes
- -------------------------------
* ssh-agent(8): the agent will now refuse requests to load PKCS#11
modules issued by remote clients by default. A flag has been added
to restore the previous behaviour "-Oallow-remote-pkcs11".
Note that ssh-agent(8) depends on the SSH client to identify
requests that are remote. The OpenSSH >=8.9 ssh(1) client does
this, but forwarding access to an agent socket using other tools
may circumvent this restriction.

- logind_set_tty.patch: tell systemd-logind our current TTY
* Thu May 11 2023 alarrosa@suse.com
- Update to openssh 9.3p1:
= Security
* ssh-add(1): when adding smartcard keys to ssh-agent(1) with the
per-hop destination constraints (ssh-add -h ...) added in
OpenSSH 8.9, a logic error prevented the constraints from being
communicated to the agent. This resulted in the keys being added
without constraints. The common cases of non-smartcard keys and
keys without destination constraints are unaffected. This
problem was reported by Luci Stanescu.
* ssh(1): Portable OpenSSH provides an implementation of the
getrrsetbyname(3) function if the standard library does not
provide it, for use by the VerifyHostKeyDNS feature. A
specifically crafted DNS response could cause this function to
perform an out-of-bounds read of adjacent stack data, but this
condition does not appear to be exploitable beyond denial-of-
service to the ssh(1) client.
The getrrsetbyname(3) replacement is only included if the
system's standard library lacks this function and portable
OpenSSH was not compiled with the ldns library (--with-ldns).
getrrsetbyname(3) is only invoked if using VerifyHostKeyDNS to
fetch SSHFP records. This problem was found by the Coverity
static analyzer.
= New features
* ssh-keygen(1), ssh-keyscan(1): accept -Ohashalg=sha1|sha256
when outputting SSHFP fingerprints to allow algorithm
selection. bz3493
* sshd(8): add a `sshd -G` option that parses and prints the
effective configuration without attempting to load private keys
and perform other checks. This allows usage of the option
before keys have been generated and for configuration
evaluation and verification by unprivileged users.
= Bugfixes
* scp(1), sftp(1): fix progressmeter corruption on wide displays;
bz3534
* ssh-add(1), ssh-keygen(1): use RSA/SHA256 when testing
usability of private keys as some systems are starting to
disable RSA/SHA1 in libcrypto.
* sftp-server(8): fix a memory leak. GHPR363
* ssh(1), sshd(8), ssh-keyscan(1): remove vestigal protocol
compatibility code and simplify what's left.
* Fix a number of low-impact Coverity static analysis findings.
These include several reported via bz2687
* ssh_config(5), sshd_config(5): mention that some options are
not first-match-wins.
* Rework logging for the regression tests. Regression tests will
now capture separate logs for each ssh and sshd invocation in
a test.
* ssh(1): make `ssh -Q CASignatureAlgorithms` work as the manpage
says it should; bz3532.
* ssh(1): ensure that there is a terminating newline when adding
a new entry to known_hosts; bz3529
= Portability
* sshd(8): harden Linux seccomp sandbox. Move to an allowlist of
mmap(2), madvise(2) and futex(2) flags, removing some
concerning kernel attack surface.
* sshd(8): improve Linux seccomp-bpf sandbox for older systems;
bz3537
- Update to openssh 9.2p1:
= Security
* sshd(8): fix a pre-authentication double-free memory fault
introduced in OpenSSH 9.1. This is not believed to be
exploitable, and it occurs in the unprivileged pre-auth process
that is subject to chroot(2) and is further sandboxed on most
major platforms.
* ssh(8): in OpenSSH releases after 8.7, the PermitRemoteOpen
option would ignore its first argument unless it was one of the
special keywords "any" or "none", causing the permission list
to fail open if only one permission was specified. bz3515
* ssh(1): if the CanonicalizeHostname and
CanonicalizePermittedCNAMEs options were enabled, and the
system/libc resolver did not check that names in DNS responses
were valid, then use of these options could allow an attacker
with control of DNS to include invalid characters (possibly
including wildcards) in names added to known_hosts files when
they were updated. These names would still have to match the
CanonicalizePermittedCNAMEs allow-list, so practical
exploitation appears unlikely.
= Potentially-incompatible changes
* ssh(1): add a new EnableEscapeCommandline ssh_config(5) option
that controls whether the client-side ~C escape sequence that
provides a command-line is available. Among other things, the
~C command-line could be used to add additional port-forwards
at runtime.
This option defaults to "no", disabling the ~C command-line
that was previously enabled by default. Turning off the
command-line allows platforms that support sandboxing of the
ssh(1) client (currently only OpenBSD) to use a stricter
default sandbox policy.
= New features
* sshd(8): add support for channel inactivity timeouts via a new
sshd_config(5) ChannelTimeout directive. This allows channels
that have not seen traffic in a configurable interval to be
automatically closed. Different timeouts may be applied to
session, X11, agent and TCP forwarding channels.
* sshd(8): add a sshd_config UnusedConnectionTimeout option to
terminate client connections that have no open channels for a
length of time. This complements the ChannelTimeout option
above.
* sshd(8): add a -V (version) option to sshd like the ssh client
has.
* ssh(1): add a "Host" line to the output of ssh -G showing the
original hostname argument. bz3343
* scp(1), sftp(1): add a -X option to both scp(1) and sftp(1) to
allow control over some SFTP protocol parameters: the copy
buffer length and the number of in-flight requests, both of
which are used during upload/download. Previously these could
be controlled in sftp(1) only. This makes them available in
both SFTP protocol clients using the same option character
sequence.
* ssh-keyscan(1): allow scanning of complete CIDR address ranges,
e.g. "ssh-keyscan 192.168.0.0/24". If a CIDR range is passed,
then it will be expanded to all possible addresses in the range
including the all-0s and all-1s addresses. bz#976
* ssh(1): support dynamic remote port forwarding in escape
command-line's -R processing. bz#3499
= Bugfixes
* ssh(1): when restoring non-blocking mode to stdio fds, restore
exactly the flags that ssh started with and don't just clobber
them with zero, as this could also remove the append flag from
the set. bz3523
* ssh(1): avoid printf("%s", NULL) if using
UserKnownHostsFile=none and a hostkey in one of the system
known hosts file changes.
* scp(1): switch scp from using pipes to a socket-pair for
communication with its ssh sub-processes, matching how sftp(1)
operates.
* sshd(8): clear signal mask early in main(); sshd may have been
started with one or more signals masked (sigprocmask(2) is not
cleared on fork/exec) and this could interfere with various
things, e.g. the login grace timer. Execution environments that
fail to clear the signal mask before running sshd are clearly
broken, but apparently they do exist.
* ssh(1): warn if no host keys for hostbased auth can be loaded.
* sshd(8): Add server debugging for hostbased auth that is queued
and sent to the client after successful authentication, but
also logged to assist in diagnosis of HostbasedAuthentication
problems. bz3507
* ssh(1): document use of the IdentityFile option as being usable
to list public keys as well as private keys. GHPR352
* sshd(8): check for and disallow MaxStartups values less than or
equal to zero during config parsing, rather than failing later
at runtime. bz3489
* ssh-keygen(1): fix parsing of hex cert expiry times specified
on the command-line when acting as a CA.
* scp(1): when scp(1) is using the SFTP protocol for transport
(the default), better match scp/rcp's handling of globs that
don't match the globbed characters but do match literally (e.g.
trying to transfer a file named "foo.[1]"). Previously scp(1)
in SFTP mode would not match these pathnames but legacy scp/rcp
mode would. bz3488
* ssh-agent(1): document the "-O no-restrict-websafe"
command-line option.
* ssh(1): honour user's umask(2) if it is more restrictive then
the ssh default (022).
= Portability
* sshd(8): allow writev(2) in the Linux seccomp sandbox. This
seems to be used by recent glibcs at least in some
configurations during error conditions. bz3512.
* sshd(8): simply handling of SSH_CONNECTION PAM env var,
removing global variable and checking the return value from
pam_putenv. bz3508
* sshd(8): disable SANDBOX_SECCOMP_FILTER_DEBUG that was
mistakenly enabled during the OpenSSH 9.1 release cycle.
* misc: update autotools and regenerate the config files using
the latest autotools
* all: use -fzero-call-used-regs=used on clang 15 instead of
- fzero-call-used-reg=all, as some versions of clang 15 have
miscompile code when it was enabled. bz3475
* sshd(8): defer PRNG seeding until after the initial
closefrom(2) call. PRNG seeding will initialize OpenSSL, and
some engine providers (e.g. Intel's QAT) will open descriptors
for their own use that closefrom(2) could clobber. bz3483
* misc: in the poll(2)/ppoll(2) compatibility code, avoid
assuming the layout of fd_set.
* sftp-server(8), ssh-agent(1): fix ptrace(2) disabling on older
FreeBSD kernels. Some versions do not support using id 0 to
refer to the current PID for procctl, so try again with
getpid() explicitly before failing.
* configure.ac: fix -Wstrict-prototypes in configure test code.
Clang 16 now warns on this and legacy prototypes will be
removed in C23. GHPR355
* configure.ac: fix setres*id checks to work with clang-16. glibc
has the prototypes for setresuid behind _GNU_SOURCE, and
clang 16 will error out on implicit function definitions.

- Update to openssh 9.1p1:

in signing/verify code; GHPR333
* ssh-keysign(8): double-free in error path introduced in

= Potentially-incompatible changes
* The portable OpenSSH project now signs commits and release tags
using git's recent SSH signature support. The list of developer
signing keys is included in the repository as
.git_allowed_signers and is cross-signed using the PGP key that
is still used to sign release artifacts:
https://cdn.openbsd.org/pub/OpenBSD/OpenSSH/RELEASE_KEY.asc
* ssh(1), sshd(8): SetEnv directives in ssh_config and
sshd_config are now first-match-wins to match other directives.
Previously if an environment variable was multiply specified
the last set value would have been used. bz3438
* ssh-keygen(8): ssh-keygen -A (generate all default host key
types) will no longer generate DSA keys, as these are insecure
and have not been used by default for some years.
= New features
* ssh(1), sshd(8): add a RequiredRSASize directive to set a
minimum RSA key length. Keys below this length will be ignored
for user authentication and for host authentication in sshd(8).
ssh(1) will terminate a connection if the server offers an RSA
key that falls below this limit, as the SSH protocol does not
include the ability to retry a failed key exchange.
* sftp-server(8): add a "users-groups-by-id@openssh.com"
extension request that allows the client to obtain user/group
names that correspond to a set of uids/gids.
* sftp(1): use "users-groups-by-id@openssh.com" sftp-server
extension (when available) to fill in user/group names for
directory listings.
* sftp-server(8): support the "home-directory" extension request
defined in draft-ietf-secsh-filexfer-extensions-00. This
overlaps a bit with the existing "expand-path@openssh.com", but
some other clients support it.
* ssh-keygen(1), sshd(8): allow certificate validity intervals,
sshsig verification times and authorized_keys expiry-time
options to accept dates in the UTC time zone in addition to the
default of interpreting them in the system time zone. YYYYMMDD
and YYMMDDHHMM[SS] dates/times will be interpreted as UTC if
suffixed with a 'Z' character.
Also allow certificate validity intervals to be specified in
raw seconds-since-epoch as hex value, e.g. -V 0x1234:0x4567890.
This is intended for use by regress tests and other tools that
call ssh-keygen as part of a CA workflow. bz3468
* sftp(1): allow arguments to the sftp -D option, e.g. sftp -D
"/usr/libexec/sftp-server -el debug3"
* ssh-keygen(1): allow the existing -U (use agent) flag to work
with "-Y sign" operations, where it will be interpreted to
require that the private keys is hosted in an agent; bz3429
= Bugfixes
* ssh-keygen(1): implement the "verify-required" certificate
option.
This was already documented when support for user-verified FIDO
keys was added, but the ssh-keygen(1) code was missing.
* ssh-agent(1): hook up the restrict_websafe command-line flag;
previously the flag was accepted but never actually used.
* sftp(1): improve filename tab completions: never try to
complete names to non-existent commands, and better match the
completion type (local or remote filename) against the argument
position being completed.
* ssh-keygen(1), ssh(1), ssh-agent(1): several fixes to FIDO key
handling, especially relating to keys that request
user-verification. These should reduce the number of
unnecessary PIN prompts for keys that support intrinsic user
verification. GHPR302, GHPR329
* ssh-keygen(1): when enrolling a FIDO resident key, check if a
credential with matching application and user ID strings
already exists and, if so, prompt the user for confirmation
before overwriting the credential. GHPR329
* sshd(8): improve logging of errors when opening authorized_keys
files. bz2042
* ssh(1): avoid multiplexing operations that could cause SIGPIPE
from causing the client to exit early. bz3454
* ssh_config(5), sshd_config(5): clarify that the RekeyLimit
directive applies to both transmitted and received data.
GHPR328
* ssh-keygen(1): avoid double fclose() in error path.
* sshd(8): log an error if pipe() fails while accepting a
connection. bz3447
* ssh(1), ssh-keygen(1): fix possible NULL deref when built
without FIDO support. bz3443
* ssh-keyscan(1): add missing *-sk types to ssh-keyscan manpage.
GHPR294.
* sshd(8): ensure that authentication passwords are cleared from
memory in error paths. GHPR286
* ssh(1), ssh-agent(1): avoid possibility of notifier code
executing kill(-1). GHPR286
* ssh_config(5): note that the ProxyJump directive also accepts
the same tokens as ProxyCommand. GHPR305.
* scp(1): do not not ftruncate(3) files early when in sftp mode.
The previous behaviour of unconditionally truncating the
destination file would cause "scp ~/foo localhost:foo" and the
reverse "scp localhost:foo ~/foo" to delete all the contents of
their destination. bz3431
* ssh-keygen(1): improve error message when 'ssh-keygen -Y sign'
is unable to load a private key; bz3429
* sftp(1), scp(1): when performing operations that glob(3) a
remote path, ensure that the implicit working directory used to
construct that path escapes glob(3) characters. This prevents
glob characters from being processed in places they shouldn't,
e.g. "cd /tmp/a*/", "get *.txt" should have the get operation
treat the path "/tmp/a*" literally and not attempt to expand
it.
* ssh(1), sshd(8): be stricter in which characters will be
accepted in specifying a mask length; allow only 0-9. GHPR278
* ssh-keygen(1): avoid printing hash algorithm twice when dumping
a KRL
* ssh(1), sshd(8): continue running local I/O for open channels
during SSH transport rekeying. This should make ~-escapes work
in the client (e.g. to exit) if the connection happened to have
stalled during a rekey event.
* ssh(1), sshd(8): avoid potential poll() spin during rekeying
* Further hardening for sshbuf internals: disallow "reparenting"
a hierarchical sshbuf and zero the entire buffer if
reallocation fails. GHPR287
= Portability
* ssh(1), ssh-keygen(1), sshd(8): automatically enable the
built-in FIDO security key support if libfido2 is found and
usable, unless --without-security-key-builtin was requested.
* ssh(1), ssh-keygen(1), sshd(8): many fixes to make the WinHello
FIDO device usable on Cygwin. The windows://hello FIDO device
will be automatically used by default on this platform unless
requested otherwise, or when probing resident FIDO credentials
(an operation not currently supported by WinHello).
* Portable OpenSSH: remove workarounds for obsolete and
unsupported versions of OpenSSL libcrypto. In particular, this
release removes fallback support for OpenSSL that lacks AES-CTR
or AES-GCM. Those AES cipher modes were added to OpenSSL prior
to the minimum version currently supported by OpenSSH, so this
is not expected to impact any currently supported
configurations.
* sshd(8): fix SANDBOX_SECCOMP_FILTER_DEBUG on current
Linux/glibc
* All: resync and clean up internal CSPRNG code.
* scp(1), sftp(1), sftp-server(8): avoid linking these programs
with unnecessary libraries. They are no longer linked against
libz and libcrypto. This may be of benefit to space constrained
systems using any of those components in isolation.
* sshd(8): add AUDIT_ARCH_PPC to supported seccomp sandbox
architectures.
* configure: remove special casing of crypt(). configure will no
longer search for crypt() in libcrypto, as it was removed from
there years ago. configure will now only search libc and
libcrypt.
* configure: refuse to use OpenSSL 3.0.4 due to potential RCE in
its RSA implementation (CVE-2022-2274) on x86_64.
* All: request 1.1x API compatibility for OpenSSL >=3.x; GHPR322
* ssh(1), ssh-keygen(1), sshd(8): fix a number of missing
includes required by the XMSS code on some platforms.
* sshd(8): cache timezone data in capsicum sandbox.
- Update to openssh 9.0p1:
= Potentially-incompatible changes
* This release switches scp(1) from using the legacy scp/rcp
protocol to using the SFTP protocol by default.
Legacy scp/rcp performs wildcard expansion of remote filenames
(e.g. "scp host:* .") through the remote shell. This has the
side effect of requiring double quoting of shell
meta-characters in file names included on scp(1) command-lines,
otherwise they could be interpreted as shell commands on the
remote side.
This creates one area of potential incompatibility: scp(1) when
using the SFTP protocol no longer requires this finicky and
brittle quoting, and attempts to use it may cause transfers to
fail. We consider the removal of the need for double-quoting
shell characters in file names to be a benefit and do not
intend to introduce bug-compatibility for legacy scp/rcp in
scp(1) when using the SFTP protocol.
Another area of potential incompatibility relates to the use of
remote paths relative to other user's home directories, for
example - "scp host:~user/file /tmp". The SFTP protocol has no
native way to expand a ~user path. However, sftp-server(8) in
OpenSSH 8.7 and later support a protocol extension
"expand-path@openssh.com" to support this.
In case of incompatibility, the scp(1) client may be instructed
to use the legacy scp/rcp using the -O flag.
= New features
* ssh(1), sshd(8): use the hybrid Streamlined NTRU Prime + x25519
key exchange method by default
("sntrup761x25519-sha512@openssh.com"). The NTRU algorithm is
believed to resist attacks enabled by future quantum computers
and is paired with the X25519 ECDH key exchange (the previous
default) as a backstop against any weaknesses in NTRU Prime
that may be discovered in the future. The combination ensures
that the hybrid exchange offers at least as good security as
the status quo.
We are making this change now (i.e. ahead of cryptographically-
relevant quantum computers) to prevent "capture now, decrypt
later" attacks where an adversary who can record and store SSH
session ciphertext would be able to decrypt it once a
sufficiently advanced quantum computer is available.
* sftp-server(8): support the "copy-data" extension to allow
server-side copying of files/data, following the design in
draft-ietf-secsh-filexfer-extensions-00. bz2948
* sftp(1): add a "cp" command to allow the sftp client to perform
server-side file copies.
= Bugfixes
* ssh(1), sshd(8): upstream: fix poll(2) spin when a channel's
output fd closes without data in the channel buffer. bz3405 and
bz3411
* sshd(8): pack pollfd array in server listen/accept loop. Could
cause the server to hang/spin when MaxStartups > RLIMIT_NOFILE
* ssh-keygen(1): avoid NULL deref via the find-principals and
check-novalidate operations. bz3409 and GHPR307 respectively.
* scp(1): fix a memory leak in argument processing. bz3404
* sshd(8): don't try to resolve ListenAddress directives in the
sshd re-exec path. They are unused after re-exec and parsing
errors (possible for example if the host's network
configuration changed) could prevent connections from being
accepted.
* sshd(8): when refusing a public key authentication request from
a client for using an unapproved or unsupported signature
algorithm include the algorithm name in the log message to make
debugging easier.
= Portability
* sshd(8): refactor platform-specific locked account check,
fixing an incorrect free() on platforms with both libiaf and
shadow passwords (probably only Unixware) GHPR284,
* ssh(1), sshd(8): Fix possible integer underflow in
scan_scaled(3) parsing of K/M/G/etc quantities. bz#3401.
* sshd(8): provide killpg implementation (mostly for Tandem
NonStop) GHPR301.
* Check for missing ftruncate prototype. GHPR301
* sshd(8): default to not using sandbox when cross compiling. On
most systems poll(2) does not work when the number of FDs is
reduced with setrlimit, so assume it doesn't when cross
compiling and we can't run the test. bz#3398.
* sshd(8): allow ppoll_time64 in seccomp sandbox. Should fix
sandbox violations on some (at least i386 and armhf) 32bit
Linux platforms. bz#3396.
* Improve detection of -fzero-call-used-regs=all support in
configure script.

- Version update to 8.9p1:
= Security
* sshd(8): fix an integer overflow in the user authentication path
that, in conjunction with other logic errors, could have yielded
unauthenticated access under difficult to exploit conditions.
This situation is not exploitable because of independent checks in
the privilege separation monitor. Privilege separation has been
enabled by default in since openssh-3.2.2 (released in 2002) and
has been mandatory since openssh-7.5 (released in 2017). Moreover,
portable OpenSSH has used toolchain features available in most
modern compilers to abort on signed integer overflow since
openssh-6.5 (released in 2014).
Thanks to Malcolm Stagg for finding and reporting this bug.
= Potentially-incompatible changes
* sshd(8), portable OpenSSH only: this release removes in-built
support for MD5-hashed passwords. If you require these on your
system then we recommend linking against libxcrypt or similar.
* This release modifies the FIDO security key middleware interface
and increments SSH_SK_VERSION_MAJOR.
= New features
* ssh(1), sshd(8), ssh-add(1), ssh-agent(1): add a system for
restricting forwarding and use of keys added to ssh-agent(1)
A detailed description of the feature is available at
https://www.openssh.com/agent-restrict.html and the protocol
extensions are documented in the PROTOCOL and PROTOCOL.agent
files in the source release.
* ssh(1), sshd(8): add the sntrup761x25519-sha512@openssh.com hybrid
ECDH/x25519 + Streamlined NTRU Prime post-quantum KEX to the
default KEXAlgorithms list (after the ECDH methods but before the
prime-group DH ones). The next release of OpenSSH is likely to
make this key exchange the default method.
* ssh-keygen(1): when downloading resident keys from a FIDO token,
pass back the user ID that was used when the key was created and
append it to the filename the key is written to (if it is not the
default). Avoids keys being clobbered if the user created multiple
resident keys with the same application string but different user
IDs.
* ssh-keygen(1), ssh(1), ssh-agent(1): better handling for FIDO keys
on tokens that provide user verification (UV) on the device itself,
including biometric keys, avoiding unnecessary PIN prompts.
* ssh-keygen(1): add "ssh-keygen -Y match-principals" operation to
perform matching of principals names against an allowed signers
file. To be used towards a TOFU model for SSH signatures in git.
* ssh-add(1), ssh-agent(1): allow pin-required FIDO keys to be added
to ssh-agent(1). $SSH_ASKPASS will be used to request the PIN at
authentication time.
* ssh-keygen(1): allow selection of hash at sshsig signing time
(either sha512 (default) or sha256).
* ssh(1), sshd(8): read network data directly to the packet input
buffer instead of indirectly via a small stack buffer. Provides a
modest performance improvement.
* ssh(1), sshd(8): read data directly to the channel input buffer,
providing a similar modest performance improvement.
* ssh(1): extend the PubkeyAuthentication configuration directive to
accept yes|no|unbound|host-bound to allow control over one of the
protocol extensions used to implement agent-restricted keys.
= Bugfixes
* sshd(8): document that CASignatureAlgorithms, ExposeAuthInfo and
PubkeyAuthOptions can be used in a Match block. PR277.
* sshd(8): fix possible string truncation when constructing paths to
.rhosts/.shosts files with very long user home directory names.
* ssh-keysign(1): unbreak for KEX algorithms that use SHA384/512
exchange hashes
* ssh(1): don't put the TTY into raw mode when SessionType=none,
avoids ^C being unable to kill such a session. bz3360
* scp(1): fix some corner-case bugs in SFTP-mode handling of
~-prefixed paths.
* ssh(1): unbreak hostbased auth using RSA keys. Allow ssh(1) to
select RSA keys when only RSA/SHA2 signature algorithms are
configured (this is the default case). Previously RSA keys were
not being considered in the default case.
* ssh-keysign(1): make ssh-keysign use the requested signature
algorithm and not the default for the key type. Part of unbreaking
hostbased auth for RSA/SHA2 keys.
* ssh(1): stricter UpdateHostkey signature verification logic on
the client- side. Require RSA/SHA2 signatures for RSA hostkeys
except when RSA/SHA1 was explicitly negotiated during initial
KEX; bz3375
* ssh(1), sshd(8): fix signature algorithm selection logic for
UpdateHostkeys on the server side. The previous code tried to
prefer RSA/SHA2 for hostkey proofs of RSA keys, but missed some
cases. This will use RSA/SHA2 signatures for RSA keys if the
client proposed these algorithms in initial KEX. bz3375
* All: convert all uses of select(2)/pselect(2) to poll(2)/ppoll(2).
This includes the mainloops in ssh(1), ssh-agent(1), ssh-agent(1)
and sftp-server(8), as well as the sshd(8) listen loop and all
other FD read/writability checks. On platforms with missing or
broken poll(2)/ppoll(2) syscalls a select(2)-based compat shim is
available.
* ssh-keygen(1): the "-Y find-principals" command was verifying key
validity when using ca certs but not with simple key lifetimes
within the allowed signers file.
* ssh-keygen(1): make sshsig verify-time argument parsing optional
* sshd(8): fix truncation in rhosts/shosts path construction.
* ssh(1), ssh-agent(1): avoid xmalloc(0) for PKCS#11 keyid for ECDSA
keys (we already did this for RSA keys). Avoids fatal errors for
PKCS#11 libraries that return empty keyid, e.g. Microchip ATECC608B
"cryptoauthlib"; bz#3364
* ssh(1), ssh-agent(1): improve the testing of credentials against
inserted FIDO: ask the token whether a particular key belongs to
it in cases where the token supports on-token user-verification
(e.g. biometrics) rather than just assuming that it will accept it.
Will reduce spurious "Confirm user presence" notifications for key
handles that relate to FIDO keys that are not currently inserted in at
least some cases. bz3366
* ssh(1), sshd(8): correct value for IPTOS_DSCP_LE. It needs to
allow for the preceding two ECN bits. bz#3373
* ssh-keygen(1): add missing -O option to usage() for the "-Y sign"
option.
* ssh-keygen(1): fix a NULL deref when using the find-principals
function, when matching an allowed_signers line that contains a
namespace restriction, but no restriction specified on the
command-line
* ssh-agent(1): fix memleak in process_extension(); oss-fuzz
issue #42719
* ssh(1): suppress "Connection to xxx closed" messages when LogLevel
is set to "error" or above. bz3378
* ssh(1), sshd(8): use correct zlib flags when inflate(3)-ing
compressed packet data. bz3372
* scp(1): when recursively transferring files in SFTP mode, create the
destination directory if it doesn't already exist to match scp(1) in
legacy RCP mode behaviour.
* scp(1): many improvements in error message consistency between scp(1)
in SFTP mode vs legacy RCP mode.
* sshd(8): fix potential race in SIGTERM handling PR289
* ssh(1), ssh(8): since DSA keys are deprecated, move them to the
end of the default list of public keys so that they will be tried
last. PR295
* ssh-keygen(1): allow 'ssh-keygen -Y find-principals' to match
wildcard principals in allowed_signers files
= Portability
* ssh(1), sshd(8): don't trust closefrom(2) on Linux. glibc's
implementation does not work in a chroot when the kernel does not
have close_range(2). It tries to read from /proc/self/fd and when
that fails dies with an assertion of sorts. Instead, call
close_range(2) directly from our compat code and fall back if
that fails. bz#3349,
* OS X poll(2) is broken; use compat replacement. For character-
special devices like /dev/null, Darwin's poll(2) returns POLLNVAL
when polled with POLLIN. Apparently this is Apple bug 3710161 -
not public but a websearch will find other OSS projects
rediscovering it periodically since it was first identified in
2005.
* Correct handling of exceptfds/POLLPRI in our select(2)-based
poll(2)/ppoll(2) compat implementation.
* Cygwin: correct checking of mbstowcs() return value.
* Add a basic SECURITY.md that refers people to the openssh.com
website.
* Enable additional compiler warnings and toolchain hardening flags,
including -Wbitwise-instead-of-logical, -Wmisleading-indentation,
- fzero-call-used-regs and -ftrivial-auto-var-init.
* HP/UX. Use compat getline(3) on HP-UX 10.x, where the libc version
is not reliable.

- Version update to 8.8p1:
= Security
* sshd(8) from OpenSSH 6.2 through 8.7 failed to correctly initialise
supplemental groups when executing an AuthorizedKeysCommand or
AuthorizedPrincipalsCommand, where a AuthorizedKeysCommandUser or
AuthorizedPrincipalsCommandUser directive has been set to run the
command as a different user. Instead these commands would inherit
the groups that sshd(8) was started with.
Depending on system configuration, inherited groups may allow
AuthorizedKeysCommand/AuthorizedPrincipalsCommand helper programs to
gain unintended privilege (bsc#1190975, CVE-2021-41617).
Neither AuthorizedKeysCommand nor AuthorizedPrincipalsCommand are
enabled by default in sshd_config(5).
= Potentially-incompatible changes
* This release disables RSA signatures using the SHA-1 hash algorithm
by default. This change has been made as the SHA-1 hash algorithm is
cryptographically broken, and it is possible to create chosen-prefix
hash collisions for <USD$50K.
For most users, this change should be invisible and there is
no need to replace ssh-rsa keys. OpenSSH has supported RFC8332
RSA/SHA-256/512 signatures since release 7.2 and existing ssh-rsa keys
will automatically use the stronger algorithm where possible.
Incompatibility is more likely when connecting to older SSH
implementations that have not been upgraded or have not closely tracked
improvements in the SSH protocol. For these cases, it may be necessary
to selectively re-enable RSA/SHA1 to allow connection and/or user
authentication via the HostkeyAlgorithms and PubkeyAcceptedAlgorithms
options.
= New features
* ssh(1): allow the ssh_config(5) CanonicalizePermittedCNAMEs
directive to accept a "none" argument to specify the default
behaviour.
= Bugfixes
* scp(1): when using the SFTP protocol, continue transferring files
after a transfer error occurs, better matching original scp/rcp
behaviour.
* ssh(1): fixed a number of memory leaks in multiplexing,
* ssh-keygen(1): avoid crash when using the -Y find-principals
command.
* A number of documentation and manual improvements, including
bz#3340, PR139, PR215, PR241, PR257
- Additional changes from 8.7p1 release:
= Potentially-incompatible changes
* scp(1): this release changes the behaviour of remote to remote
copies (e.g. "scp host-a:/path host-b:") to transfer through the
local host by default. This was previously available via the -3
flag. This mode avoids the need to expose credentials on the
origin hop, avoids triplicate interpretation of filenames by the
shell (by the local system, the copy origin and the destination)
and, in conjunction with the SFTP support for scp(1) mentioned
below, allows use of all authentication methods to the remote
hosts (previously, only non-interactive methods could be used).
A -R flag has been added to select the old behaviour.
* ssh(1)/sshd(8): both the client and server are now using a
stricter configuration file parser. The new parser uses more
shell-like rules for quotes, space and escape characters. It is
also more strict in rejecting configurations that include options
lacking arguments. Previously some options (e.g. DenyUsers) could
appear on a line with no subsequent arguments. This release will
reject such configurations. The new parser will also reject
configurations with unterminated quotes and multiple '='
characters after the option name.
* ssh(1): when using SSHFP DNS records for host key verification,
ssh(1) will verify all matching records instead of just those
with the specific signature type requested. This may cause host
key verification problems if stale SSHFP records of a different
or legacy signature type exist alongside other records for a
particular host. bz#3322
* ssh-keygen(1): when generating a FIDO key and specifying an
explicit attestation challenge (using -Ochallenge), the challenge
will now be hashed by the builtin security key middleware. This
removes the (undocumented) requirement that challenges be exactly
32 bytes in length and matches the expectations of libfido2.
* sshd(8): environment="..." directives in authorized_keys files are
now first-match-wins and limited to 1024 discrete environment
variable names.
= New features
* scp(1): experimental support for transfers using the SFTP protocol
as a replacement for the venerable SCP/RCP protocol that it has
traditionally used. SFTP offers more predictable filename handling
and does not require expansion of glob(3) patterns via the shell
on the remote side.
* sftp-server(8): add a protocol extension to support expansion of
~/ and ~user/ prefixed paths. This was added to support these
paths when used by scp(1) while in SFTP mode.
* ssh(1): add a ForkAfterAuthentication ssh_config(5) counterpart to
the ssh(1) -f flag. GHPR231
* ssh(1): add a StdinNull directive to ssh_config(5) that allows the
config file to do the same thing as -n does on the ssh(1) command-
line. GHPR231
* ssh(1): add a SessionType directive to ssh_config, allowing the
configuration file to offer equivalent control to the -N (no
session) and -s (subsystem) command-line flags. GHPR231
* ssh-keygen(1): allowed signers files used by ssh-keygen(1)
signatures now support listing key validity intervals alongside
they key, and ssh-keygen(1) can optionally check during signature
verification whether a specified time falls inside this interval.
This feature is intended for use by git to support signing and
verifying objects using ssh keys.
* ssh-keygen(8): support printing of the full public key in a sshsig
signature via a -Oprint-pubkey flag.
= Bugfixes
* ssh(1)/sshd(8): start time-based re-keying exactly on schedule in
the client and server mainloops. Previously the re-key timeout
could expire but re-keying would not start until a packet was sent
or received, causing a spin in select() if the connection was
quiescent.
* ssh-keygen(1): avoid Y2038 problem in printing certificate
validity lifetimes. Dates past 2^31-1 seconds since epoch were
displayed incorrectly on some platforms. bz#3329
* scp(1): allow spaces to appear in usernames for local to remote
and scp -3 remote to remote copies. bz#1164
* ssh(1)/sshd(8): remove references to ChallengeResponseAuthentication
in favour of KbdInteractiveAuthentication. The former is what was in
SSHv1, the latter is what is in SSHv2 (RFC4256) and they were
treated as somewhat but not entirely equivalent. We retain the old
name as a deprecated alias so configuration files continue to work
as well as a reference in the man page for people looking for it.
bz#3303
* ssh(1)/ssh-add(1)/ssh-keygen(1): fix decoding of X.509 subject name
when extracting a key from a PKCS#11 certificate. bz#3327
* ssh(1): restore blocking status on stdio fds before close. ssh(1)
needs file descriptors in non-blocking mode to operate but it was
not restoring the original state on exit. This could cause
problems with fds shared with other programs via the shell,
bz#3280 and GHPR246
* ssh(1)/sshd(8): switch both client and server mainloops from
select(3) to pselect(3). Avoids race conditions where a signal
may arrive immediately before select(3) and not be processed until
an event fires. bz#2158
* ssh(1): sessions started with ControlPersist were incorrectly
executing a shell when the -N (no shell) option was specified.
bz#3290
* ssh(1): check if IPQoS or TunnelDevice are already set before
overriding. Prevents values in config files from overriding values
supplied on the command line. bz#3319
* ssh(1): fix debug message when finding a private key to match a
certificate being attempted for user authentication. Previously it
would print the certificate's path, whereas it was supposed to be
showing the private key's path. GHPR247
* sshd(8): match host certificates against host public keys, not
private keys. Allows use of certificates with private keys held in
a ssh-agent. bz#3524
* ssh(1): add a workaround for a bug in OpenSSH 7.4 sshd(8), which
allows RSA/SHA2 signatures for public key authentication but fails
to advertise this correctly via SSH2_MSG_EXT_INFO. This causes
clients of these server to incorrectly match
PubkeyAcceptedAlgorithmse and potentially refuse to offer valid
keys. bz#3213
* sftp(1)/scp(1): degrade gracefully if a sftp-server offers the
limits@openssh.com extension but fails when the client tries to
invoke it. bz#3318
* ssh(1): allow ssh_config SetEnv to override $TERM, which is
otherwise handled specially by the protocol. Useful in ~/.ssh/config
to set TERM to something generic (e.g. "xterm" instead of
"xterm-256color") for destinations that lack terminfo entries.
* sftp-server(8): the limits@openssh.com extension was incorrectly
marked as an operation that writes to the filesystem, which made it
unavailable in sftp-server read-only mode. bz#3318
* ssh(1): fix SEGV in UpdateHostkeys debug() message, triggered when
the update removed more host keys than remain present.
* Many manual page fixes.
- Additional changes from 8.6p1 release:
= Security
* sshd(8): OpenSSH 8.5 introduced the LogVerbose keyword. When this
option was enabled with a set of patterns that activated logging
in code that runs in the low-privilege sandboxed sshd process, the
log messages were constructed in such a way that printf(3) format
strings could effectively be specified the low-privilege code.
= New features
* sftp-server(8): add a new limits@openssh.com protocol extension
that allows a client to discover various server limits, including
maximum packet size and maximum read/write length.
* sftp(1): use the new limits@openssh.com extension (when available)
to select better transfer lengths in the client.
* sshd(8): Add ModuliFile keyword to sshd_config to specify the
location of the "moduli" file containing the groups for DH-GEX.
* unit tests: Add a TEST_SSH_ELAPSED_TIMES environment variable to
enable printing of the elapsed time in seconds of each test.
= Bugfixes
* ssh_config(5), sshd_config(5): sync CASignatureAlgorithms lists in
manual pages with the current default. GHPR174
* ssh(1): ensure that pkcs11_del_provider() is called before exit.
GHPR234
* ssh(1), sshd(8): fix problems in string->argv conversion. Multiple
backslashes were not being dequoted correctly and quoted space in
the middle of a string was being incorrectly split. GHPR223
* ssh(1): return non-zero exit status when killed by signal; bz#3281
* sftp-server(8): increase maximum SSH2_FXP_READ to match the maximum
packet size. Also handle zero-length reads that are not explicitly
banned by the spec.
- Additional changes from 8.5p1 release:
= Security
* ssh-agent(1): fixed a double-free memory corruption that was
introduced in OpenSSH 8.2 . We treat all such memory faults as
potentially exploitable. This bug could be reached by an attacker
with access to the agent socket (bsc#1183137, CVE-2021-28041)
= Potentially-incompatible changes
* ssh(1), sshd(8): this release changes the first-preference signature
algorithm from ECDSA to ED25519.
* ssh(1), sshd(8): set the TOS/DSCP specified in the configuration
for interactive use prior to TCP connect. The connection phase of
the SSH session is time-sensitive and often explicitly interactive.
The ultimate interactive/bulk TOS/DSCP will be set after
authentication completes.
* ssh(1), sshd(8): remove the pre-standardization cipher
rijndael-cbc@lysator.liu.se. It is an alias for aes256-cbc before
it was standardized in RFC4253 (2006), has been deprecated and
disabled by default since OpenSSH 7.2 (2016) and was only briefly
documented in ssh.1 in 2001.
* ssh(1), sshd(8): update/replace the experimental post-quantum
hybrid key exchange method based on Streamlined NTRU Prime coupled
with X25519. The previous sntrup4591761x25519-sha512@tinyssh.org
method is replaced with sntrup761x25519-sha512@openssh.com.
* ssh(1): disable CheckHostIP by default. It provides insignificant
benefits while making key rotation significantly more difficult,
especially for hosts behind IP-based load-balancers.
= New features
* ssh(1): this release enables UpdateHostkeys by default subject to
some conservative preconditions:
- The key was matched in the UserKnownHostsFile (and not in the
GlobalKnownHostsFile).
- The same key does not exist under another name.
- A certificate host key is not in use.
- known_hosts contains no matching wildcard hostname pattern.
- VerifyHostKeyDNS is not enabled.
- The default UserKnownHostsFile is in use.
* ssh(1), sshd(8): add a new LogVerbose configuration directive for
that allows forcing maximum debug logging by file/function/line
pattern-lists.
* ssh(1): when prompting the user to accept a new hostkey, display
any other host names/addresses already associated with the key.
* ssh(1): allow UserKnownHostsFile=none to indicate that no
known_hosts file should be used to identify host keys.
* ssh(1): add a ssh_config KnownHostsCommand option that allows the
client to obtain known_hosts data from a command in addition to
the usual files.
* ssh(1): add a ssh_config PermitRemoteOpen option that allows the
client to restrict the destination when RemoteForward is used
with SOCKS.
* ssh(1): for FIDO keys, if a signature operation fails with a
"incorrect PIN" reason and no PIN was initially requested from the
user, then request a PIN and retry the operation. This supports
some biometric devices that fall back to requiring PIN when reading
of the biometric failed, and devices that require PINs for all
hosted credentials.
* sshd(8): implement client address-based rate-limiting via new
sshd_config(5) PerSourceMaxStartups and PerSourceNetBlockSize
directives that provide more fine-grained control on a per-origin
address basis than the global MaxStartups limit.
= Bugfixes
* ssh(1): Prefix keyboard interactive prompts with "(user@host)" to
make it easier to determine which connection they are associated
with in cases like scp -3, ProxyJump, etc. bz#3224
* sshd(8): fix sshd_config SetEnv directives located inside Match
blocks. GHPR201
* ssh(1): when requesting a FIDO token touch on stderr, inform the
user once the touch has been recorded.
* ssh(1): prevent integer overflow when ridiculously large
ConnectTimeout values are specified, capping the effective value
(for most platforms) at 24 days. bz#3229
* ssh(1): consider the ECDSA key subtype when ordering host key
algorithms in the client.
* ssh(1), sshd(8): rename the PubkeyAcceptedKeyTypes keyword to
PubkeyAcceptedAlgorithms. The previous name incorrectly suggested
that it control allowed key algorithms, when this option actually
specifies the signature algorithms that are accepted. The previous
name remains available as an alias. bz#3253
* ssh(1), sshd(8): similarly, rename HostbasedKeyTypes (ssh) and
HostbasedAcceptedKeyTypes (sshd) to HostbasedAcceptedAlgorithms.
* sftp-server(8): add missing lsetstat@openssh.com documentation
and advertisement in the server's SSH2_FXP_VERSION hello packet.
* ssh(1), sshd(8): more strictly enforce KEX state-machine by
banning packet types once they are received. Fixes memleak caused
by duplicate SSH2_MSG_KEX_DH_GEX_REQUEST (oss-fuzz #30078).
* sftp(1): allow the full range of UIDs/GIDs for chown/chgrp on 32bit
platforms instead of being limited by LONG_MAX. bz#3206
* Minor man page fixes (capitalization, commas, etc.) bz#3223
* sftp(1): when doing an sftp recursive upload or download of a
read-only directory, ensure that the directory is created with
write and execute permissions in the interim so that the transfer
can actually complete, then set the directory permission as the
final step. bz#3222
* ssh-keygen(1): document the -Z, check the validity of its argument
earlier and provide a better error message if it's not correct.
bz#2879
* ssh(1): ignore comments at the end of config lines in ssh_config,
similar to what we already do for sshd_config. bz#2320
* sshd_config(5): mention that DisableForwarding is valid in a
sshd_config Match block. bz3239
* sftp(1): fix incorrect sorting of "ls -ltr" under some
circumstances. bz3248.
* ssh(1), sshd(8): fix potential integer truncation of (unlikely)
timeout values. bz#3250
* ssh(1): make hostbased authentication send the signature algorithm
in its SSH2_MSG_USERAUTH_REQUEST packets instead of the key type.
This make HostbasedAcceptedAlgorithms do what it is supposed to -
filter on signature algorithm and not key type.

- update to 8.4p1:
Security
========
* ssh-agent(1): restrict ssh-agent from signing web challenges for
FIDO/U2F keys.
* ssh-keygen(1): Enable FIDO 2.1 credProtect extension when generating
a FIDO resident key.
* ssh(1), ssh-keygen(1): support for FIDO keys that require a PIN for
each use. These keys may be generated using ssh-keygen using a new
"verify-required" option. When a PIN-required key is used, the user
will be prompted for a PIN to complete the signature operation.
New Features
- -----------
* sshd(8): authorized_keys now supports a new "verify-required"
option to require FIDO signatures assert that the token verified
that the user was present before making the signature. The FIDO
protocol supports multiple methods for user-verification, but
currently OpenSSH only supports PIN verification.
* sshd(8), ssh-keygen(1): add support for verifying FIDO webauthn
signatures. Webauthn is a standard for using FIDO keys in web
browsers. These signatures are a slightly different format to plain
FIDO signatures and thus require explicit support.
* ssh(1): allow some keywords to expand shell-style ${ENV}
environment variables. The supported keywords are CertificateFile,
ControlPath, IdentityAgent and IdentityFile, plus LocalForward and
RemoteForward when used for Unix domain socket paths. bz#3140
* ssh(1), ssh-agent(1): allow some additional control over the use of
ssh-askpass via a new $SSH_ASKPASS_REQUIRE environment variable,
including forcibly enabling and disabling its use. bz#69
* ssh(1): allow ssh_config(5)'s AddKeysToAgent keyword accept a time
limit for keys in addition to its current flag options. Time-
limited keys will automatically be removed from ssh-agent after
their expiry time has passed.
* scp(1), sftp(1): allow the -A flag to explicitly enable agent
forwarding in scp and sftp. The default remains to not forward an
agent, even when ssh_config enables it.
* ssh(1): add a '%k' TOKEN that expands to the effective HostKey of
the destination. This allows, e.g., keeping host keys in individual
files using "UserKnownHostsFile ~/.ssh/known_hosts.d/%k". bz#1654
* ssh(1): add %-TOKEN, environment variable and tilde expansion to
the UserKnownHostsFile directive, allowing the path to be
completed by the configuration (e.g. bz#1654)
* ssh-keygen(1): allow "ssh-add -d -" to read keys to be deleted
from stdin. bz#3180
* sshd(8): improve logging for MaxStartups connection throttling.
sshd will now log when it starts and stops throttling and periodically
while in this state. bz#3055
Bugfixes
- -------
* ssh(1), ssh-keygen(1): better support for multiple attached FIDO
tokens. In cases where OpenSSH cannot unambiguously determine which
token to direct a request to, the user is now required to select a
token by touching it. In cases of operations that require a PIN to
be verified, this avoids sending the wrong PIN to the wrong token
and incrementing the token's PIN failure counter (tokens
effectively erase their keys after too many PIN failures).
* sshd(8): fix Include before Match in sshd_config; bz#3122
* ssh(1): close stdin/out/error when forking after authentication
completes ("ssh -f ...") bz#3137
* ssh(1), sshd(8): limit the amount of channel input data buffered,
avoiding peers that advertise large windows but are slow to read
from causing high memory consumption.
* ssh-agent(1): handle multiple requests sent in a single write() to
the agent.
* sshd(8): allow sshd_config longer than 256k
* sshd(8): avoid spurious "Unable to load host key" message when sshd
load a private key but no public counterpart
* ssh(1): prefer the default hostkey algorithm list whenever we have
a hostkey that matches its best-preference algorithm.
* sshd(1): when ordering the hostkey algorithms to request from a
server, prefer certificate types if the known_hosts files contain a key
marked as a @cert-authority; bz#3157
* ssh(1): perform host key fingerprint comparisons for the "Are you
sure you want to continue connecting (yes/no/[fingerprint])?"
prompt with case sensitivity.
* sshd(8): ensure that address/masklen mismatches in sshd_config
yield fatal errors at daemon start time rather than later when
they are evaluated.
* ssh-keygen(1): ensure that certificate extensions are lexically
sorted. Previously if the user specified a custom extension then
the everything would be in order except the custom ones. bz#3198
* ssh(1): also compare username when checking for JumpHost loops.
bz#3057
* ssh-keygen(1): preserve group/world read permission on known_hosts
files across runs of "ssh-keygen -Rf /path". The old behaviour was
to remove all rights for group/other. bz#3146
* ssh-keygen(1): Mention the [-a rounds] flag in the ssh-keygen
manual page and usage().
* sshd(8): explicitly construct path to ~/.ssh/rc rather than
relying on it being relative to the current directory, so that it
can still be found if the shell startup changes its directory.
bz#3185
* sshd(8): when redirecting sshd's log output to a file, undo this
redirection after the session child process is forked(). Fixes
missing log messages when using this feature under some
circumstances.
* sshd(8): start ClientAliveInterval bookkeeping before first pass
through select() loop; fixed theoretical case where busy sshd may
ignore timeouts from client.
* ssh(1): only reset the ServerAliveInterval check when we receive
traffic from the server and ignore traffic from a port forwarding
client, preventing a client from keeping a connection alive when
it should be terminated. bz#2265
* ssh-keygen(1): avoid spurious error message when ssh-keygen
creates files outside ~/.ssh
* sftp-client(1): fix off-by-one error that caused sftp downloads to
make one more concurrent request that desired. This prevented using
sftp(1) in unpipelined request/response mode, which is useful when
debugging. bz#3054
* ssh(1), sshd(8): handle EINTR in waitfd() and timeout_connect()
helpers. bz#3071
* ssh(1), ssh-keygen(1): defer creation of ~/.ssh until we attempt to
write to it so we don't leave an empty .ssh directory when it's not
needed. bz#3156
* ssh(1), sshd(8): fix multiplier when parsing time specifications
when handling seconds after other units. bz#3171
* Fri Jan 08 2021 hpj@suse.com
- Update openssh-8.1p1-audit.patch (bsc#1180501). This fixes
occasional crashes on connection termination caused by accessing
freed memory.
* Fri Nov 27 2020 kukuk@suse.com
- Support /usr/etc/pam.d
* Wed Nov 11 2020 hpj@suse.com
- Fix build breakage caused by missing security key objects:
+ Modify openssh-7.7p1-cavstest-ctr.patch.
+ Modify openssh-7.7p1-cavstest-kdf.patch.
+ Add openssh-link-with-sk.patch.
* Wed Nov 11 2020 hpj@suse.com
- Add openssh-fips-ensure-approved-moduli.patch (bsc#1177939).
This ensures only approved DH parameters are used in FIPS mode.
* Wed Nov 11 2020 hpj@suse.com
- Add openssh-8.1p1-ed25519-use-openssl-rng.patch (bsc#1173799).
This uses OpenSSL's RAND_bytes() directly instead of the internal
ChaCha20-based implementation to obtain random bytes for Ed25519
curve computations. This is required for FIPS compliance.
* Thu Oct 08 2020 hpj@suse.com
- Work around %service_add_post disabling sshd on upgrade with
package name change (bsc#1177039).
* Fri Sep 25 2020 dimstar@opensuse.org
- Fix fillup-template usage:
+ %post server needs to reference ssh (not sshd), which matches
the sysconfig.ssh file name the package ships.
+ %post client does not need any fillup_ calls, as there is no
client-relevant sysconfig file present. The naming of the
sysconfig file (ssh instead of sshd) is unfortunate.
* Fri Sep 25 2020 fbui@suse.com
- Use of DISABLE_RESTART_ON_UPDATE is deprecated.
Replace it with %service_del_postun_without_restart
* Thu Sep 17 2020 jengelh@inai.de
- Move some Requires to the right subpackage.
- Avoid ">&" bashism in %post.
- Upgrade some old specfile constructs/macros and drop unnecessary
%{?systemd_*}.
- Trim descriptions and straighten out the grammar.
* Thu Sep 10 2020 hpj@suse.com
- Split openssh package into openssh, openssh-common,
openssh-server and openssh-clients. This allows for the ssh
clients to be installed without the server component
(bsc#1176434).
* Fri Jun 05 2020 hpj@suse.com
- Version update to 8.3p1:
= Potentially-incompatible changes
* sftp(1): reject an argument of "-1" in the same way as ssh(1) and
scp(1) do instead of accepting and silently ignoring it.
= New features
* sshd(8): make IgnoreRhosts a tri-state option: "yes" to ignore
rhosts/shosts, "no" allow rhosts/shosts or (new) "shosts-only"
to allow .shosts files but not .rhosts.
* sshd(8): allow the IgnoreRhosts directive to appear anywhere in a
sshd_config, not just before any Match blocks.
* ssh(1): add %TOKEN percent expansion for the LocalFoward and
RemoteForward keywords when used for Unix domain socket forwarding.
* all: allow loading public keys from the unencrypted envelope of a
private key file if no corresponding public key file is present.
* ssh(1), sshd(8): prefer to use chacha20 from libcrypto where
possible instead of the (slower) portable C implementation included
in OpenSSH.
* ssh-keygen(1): add ability to dump the contents of a binary key
revocation list via "ssh-keygen -lQf /path".
- Additional changes from 8.2p1 release:
= Potentially-incompatible changes
* ssh(1), sshd(8), ssh-keygen(1): this release removes the "ssh-rsa"
(RSA/SHA1) algorithm from those accepted for certificate signatures
(i.e. the client and server CASignatureAlgorithms option) and will
use the rsa-sha2-512 signature algorithm by default when the
ssh-keygen(1) CA signs new certificates.
* ssh(1), sshd(8): this release removes diffie-hellman-group14-sha1
from the default key exchange proposal for both the client and
server.
* ssh-keygen(1): the command-line options related to the generation
and screening of safe prime numbers used by the
diffie-hellman-group-exchange-* key exchange algorithms have
changed. Most options have been folded under the -O flag.
* sshd(8): the sshd listener process title visible to ps(1) has
changed to include information about the number of connections that
are currently attempting authentication and the limits configured
by MaxStartups.
* ssh-sk-helper(8): this is a new binary. It is used by the FIDO/U2F
support to provide address-space isolation for token middleware
libraries (including the internal one). It needs to be installed
in the expected path, typically under /usr/libexec or similar.
= New features
* This release adds support for FIDO/U2F hardware authenticators to
OpenSSH. U2F/FIDO are open standards for inexpensive two-factor
authentication hardware that are widely used for website
authentication. In OpenSSH FIDO devices are supported by new public
key types "ecdsa-sk" and "ed25519-sk", along with corresponding
certificate types.
* sshd(8): add an Include sshd_config keyword that allows including
additional configuration files via glob(3) patterns.
* ssh(1)/sshd(8): make the LE (low effort) DSCP code point available
via the IPQoS directive.
* ssh(1): when AddKeysToAgent=yes is set and the key contains no
comment, add the key to the agent with the key's path as the
comment.
* ssh-keygen(1), ssh-agent(1): expose PKCS#11 key labels and X.509
subjects as key comments, rather than simply listing the PKCS#11
provider library path.
* ssh-keygen(1): allow PEM export of DSA and ECDSA keys.
* ssh(1), sshd(8): make zlib compile-time optional, available via the
Makefile.inc ZLIB flag on OpenBSD or via the --with-zlib configure
option for OpenSSH portable.
* sshd(8): when clients get denied by MaxStartups, send a
notification prior to the SSH2 protocol banner according to
RFC4253 section 4.2.
* ssh(1), ssh-agent(1): when invoking the $SSH_ASKPASS prompt
program, pass a hint to the program to describe the type of
desired prompt. The possible values are "confirm" (indicating
that a yes/no confirmation dialog with no text entry should be
shown), "none" (to indicate an informational message only), or
blank for the original ssh-askpass behaviour of requesting a
password/phrase.
* ssh(1): allow forwarding a different agent socket to the path
specified by $SSH_AUTH_SOCK, by extending the existing ForwardAgent
option to accepting an explicit path or the name of an environment
variable in addition to yes/no.
* ssh-keygen(1): add a new signature operations "find-principals" to
look up the principal associated with a signature from an allowed-
signers file.
* sshd(8): expose the number of currently-authenticating connections
along with the MaxStartups limit in the process title visible to
"ps".

- Update openssh-7.7p1-audit.patch to fix crash (bsc#1152730). Fix
by Enzo Matsumiya (ematsumiya@suse.com). This was integrated in
a separate code stream merged with the Oct. 10 update; the patch
was also rebased and renamed to openssh-8.1p1-audit.patch.
* Mon Oct 14 2019 hpj@suse.com
- Add openssh-7.9p1-keygen-preserve-perms.patch (bsc#1150574).
This attempts to preserve the permissions of any existing
known_hosts file when modified by ssh-keygen (for instance,
with -R).
- Added openssh-7.9p1-revert-new-qos-defaults.patch, which reverts
an upstream commit that caused compatibility issues with other
software (bsc#1136402).
* Mon Oct 14 2019 hpj@suse.com
- Run 'ssh-keygen -A' on startup only if SSHD_AUTO_KEYGEN="yes"
in /etc/sysconfig/ssh. This is set to "yes" by default, but
can be changed by the system administrator (bsc#1139089).
* Mon Oct 14 2019 hpj@suse.com
- Add openssh-7.9p1-keygen-preserve-perms.patch (bsc#1150574).
This attempts to preserve the permissions of any existing
known_hosts file when modified by ssh-keygen (for instance,
with -R).
* Thu Oct 10 2019 hpj@suse.com
- Version update to 8.1p1:
* ssh-keygen(1): when acting as a CA and signing certificates with
an RSA key, default to using the rsa-sha2-512 signature algorithm.
Certificates signed by RSA keys will therefore be incompatible
with OpenSSH versions prior to 7.2 unless the default is
overridden (using "ssh-keygen -t ssh-rsa -s ...").
* ssh(1): Allow %n to be expanded in ProxyCommand strings
* ssh(1), sshd(8): Allow prepending a list of algorithms to the
default set by starting the list with the '^' character, E.g.
"HostKeyAlgorithms ^ssh-ed25519"
* ssh-keygen(1): add an experimental lightweight signature and
verification ability. Signatures may be made using regular ssh keys
held on disk or stored in a ssh-agent and verified against an
authorized_keys-like list of allowed keys. Signatures embed a
namespace that prevents confusion and attacks between different
usage domains (e.g. files vs email).
* ssh-keygen(1): print key comment when extracting public key from a
private key.
* ssh-keygen(1): accept the verbose flag when searching for host keys
in known hosts (i.e. "ssh-keygen -vF host") to print the matching
host's random-art signature too.
* All: support PKCS8 as an optional format for storage of private
keys to disk. The OpenSSH native key format remains the default,
but PKCS8 is a superior format to PEM if interoperability with
non-OpenSSH software is required, as it may use a less insecure
key derivation function than PEM's.
- Additional changes from 8.0p1 release:
* scp(1): Add "-T" flag to disable client-side filtering of
server file list.
* sshd(8): Remove support for obsolete "host/port" syntax.
* ssh(1), ssh-agent(1), ssh-add(1): Add support for ECDSA keys in
PKCS#11 tokens.
* ssh(1), sshd(8): Add experimental quantum-computing resistant
key exchange method, based on a combination of Streamlined NTRU
Prime 4591^761 and X25519.
* ssh-keygen(1): Increase the default RSA key size to 3072 bits,
following NIST Special Publication 800-57's guidance for a
128-bit equivalent symmetric security level.
* ssh(1): Allow "PKCS11Provider=none" to override later instances of
the PKCS11Provider directive in ssh_config,
* sshd(8): Add a log message for situations where a connection is
dropped for attempting to run a command but a sshd_config
ForceCommand=internal-sftp restriction is in effect.
* ssh(1): When prompting whether to record a new host key, accept
the key fingerprint as a synonym for "yes". This allows the user
to paste a fingerprint obtained out of band at the prompt and
have the client do the comparison for you.
* ssh-keygen(1): When signing multiple certificates on a single
command-line invocation, allow automatically incrementing the
certificate serial number.
* scp(1), sftp(1): Accept -J option as an alias to ProxyJump on
the scp and sftp command-lines.
* ssh-agent(1), ssh-pkcs11-helper(8), ssh-add(1): Accept "-v"
command-line flags to increase the verbosity of output; pass
verbose flags though to subprocesses, such as ssh-pkcs11-helper
started from ssh-agent.
* ssh-add(1): Add a "-T" option to allowing testing whether keys in
an agent are usable by performing a signature and a verification.
* sftp-server(8): Add a "lsetstat@openssh.com" protocol extension
that replicates the functionality of the existing SSH2_FXP_SETSTAT
operation but does not follow symlinks.
* sftp(1): Add "-h" flag to chown/chgrp/chmod commands to request
they do not follow symlinks.
* sshd(8): Expose $SSH_CONNECTION in the PAM environment. This makes
the connection 4-tuple available to PAM modules that wish to use
it in decision-making.
* sshd(8): Add a ssh_config "Match final" predicate Matches in same
pass as "Match canonical" but doesn't require hostname
canonicalisation be enabled.
* sftp(1): Support a prefix of '@' to suppress echo of sftp batch
commands.
* ssh-keygen(1): When printing certificate contents using
"ssh-keygen -Lf /path/certificate", include the algorithm that
the CA used to sign the cert.

It used to allow lowering of the minimal allowed DH group size,
which was increased to 2048 by upstream in the light of the Logjam
attack.
The code was broken since the upgrade to 7.6p1, but nobody noticed.
As apparently no one needs the functionality any more, let's drop
the patch.
It's still possible to use the fixed 1024-bit diffie-hellman-group1-sha1
key exchange method when working with legacy systems.

mm_answer_keyverify: buffer error: incomplete message [bnc#1114008]
* Mon Oct 22 2018 pmonrealgonzalez@suse.com
- Version update to 7.9p1
* ssh(1), sshd(8): the setting of the new CASignatureAlgorithms
option (see below) bans the use of DSA keys as certificate
authorities.
* sshd(8): the authentication success/failure log message has
changed format slightly. It now includes the certificate
fingerprint (previously it included only key ID and CA key
fingerprint).
* ssh(1), sshd(8): allow most port numbers to be specified using
service names from getservbyname(3) (typically /etc/services).
* sshd(8): support signalling sessions via the SSH protocol.
A limited subset of signals is supported and only for login or
command sessions (i.e. not subsystems) that were not subject to
a forced command via authorized_keys or sshd_config. bz#1424
* ssh(1): support "ssh -Q sig" to list supported signature options.
Also "ssh -Q help" to show the full set of supported queries.
* ssh(1), sshd(8): add a CASignatureAlgorithms option for the
client and server configs to allow control over which signature
formats are allowed for CAs to sign certificates. For example,
this allows banning CAs that sign certificates using the RSA-SHA1
signature algorithm.
* sshd(8), ssh-keygen(1): allow key revocation lists (KRLs) to
revoke keys specified by SHA256 hash.
* ssh-keygen(1): allow creation of key revocation lists directly
from base64-encoded SHA256 fingerprints. This supports revoking
keys using only the information contained in sshd(8)
authentication log messages.

- Upgrade to 7.7p1 (bsc#1094068)
Most important changes (more details below):
* Drop compatibility support for pre-2001 SSH implementations
* sshd(1) does not load DSA keys by default
Distilled upstream log:
- --- Potentially-incompatible changes
* ssh(1)/sshd(8): Drop compatibility support for some very old
SSH implementations, including ssh.com <=2.* and OpenSSH <=
3.*. These versions were all released in or before 2001 and
predate the final SSH RFCs. The support in question isn't
necessary for RFC-compliant SSH implementations.
- --- New Features
* experimental support for PQC XMSS keys (Extended Hash-Based
Signatures), not compiled in by default.
* sshd(8): Add a "rdomain" criteria for the sshd_config Match
keyword to allow conditional configuration that depends on
which routing domain a connection was received on (currently
supported on OpenBSD and Linux).
* sshd_config(5): Add an optional rdomain qualifier to the
ListenAddress directive to allow listening on different
routing domains. This is supported only on OpenBSD and Linux
at present.
* sshd_config(5): Add RDomain directive to allow the
authenticated session to be placed in an explicit routing
domain. This is only supported on OpenBSD at present.
* sshd(8): Add "expiry-time" option for authorized_keys files
to allow for expiring keys.
* ssh(1): Add a BindInterface option to allow binding the
outgoing connection to an interface's address (basically a
more usable BindAddress)
* ssh(1): Expose device allocated for tun/tap forwarding via a
new %T expansion for LocalCommand. This allows LocalCommand
to be %used to prepare the interface.
* sshd(8): Expose the device allocated for tun/tap forwarding
via a new SSH_TUNNEL environment variable. This allows
automatic setup of the interface and surrounding network
configuration automatically on the server.
* ssh(1)/scp(1)/sftp(1): Add URI support to ssh, sftp and scp,
e.g. ssh://user@host or sftp://user@host/path. Additional
connection parameters that use deporecated MD5 are not
implemented.
* ssh-keygen(1): Allow certificate validity intervals that
specify only a start or stop time (instead of both or
neither).
* sftp(1): Allow "cd" and "lcd" commands with no explicit path
argument. lcd will change to the local user's home directory
as usual. cd will change to the starting directory for
session (because the protocol offers no way to obtain the
remote user's home directory). bz#2760
* sshd(8): When doing a config test with sshd -T, only require
the attributes that are actually used in Match criteria
rather than (an incomplete list of) all criteria.
- --- Bugfixes
* ssh(1)/sshd(8): More strictly check signature types during
key exchange against what was negotiated. Prevents downgrade
of RSA signatures made with SHA-256/512 to SHA-1.
* sshd(8): Fix support for client that advertise a protocol
version of "1.99" (indicating that they are prepared to
accept both SSHv1 and SSHv2). This was broken in OpenSSH 7.6
during the removal of SSHv1 support. bz#2810
* ssh(1): Warn when the agent returns a ssh-rsa (SHA1)
signature when a rsa-sha2-256/512 signature was requested.
This condition is possible when an old or non-OpenSSH agent
is in use. bz#2799
* ssh-agent(1): Fix regression introduced in 7.6 that caused
ssh-agent to fatally exit if presented an invalid signature
request message.
* sshd_config(5): Accept yes/no flag options
case-insensitively, as has been the case in ssh_config(5) for
a long time. bz#2664
* ssh(1): Improve error reporting for failures during
connection. Under some circumstances misleading errors were
being shown. bz#2814
* ssh-keyscan(1): Add -D option to allow printing of results
directly in SSHFP format. bz#2821

release's SSHv1 removal. bz#2823
* ssh(1): Compatibility fix for some servers that erroneously
drop the connection when the IUTF8 (RFC8160) option is sent.
* scp(1): Disable RemoteCommand and RequestTTY in the ssh
session started by scp (sftp was already doing this.)
* ssh-keygen(1): Refuse to create a certificate with an
unusable number of principals.
* ssh-keygen(1): Fatally exit if ssh-keygen is unable to write
all the public key during key generation. Previously it would
silently ignore errors writing the comment and terminating
newline.
* ssh(1): Do not modify hostname arguments that are addresses
by automatically forcing them to lower-case. Instead
canonicalise them to resolve ambiguities (e.g. ::0001 => ::1)
before they are matched against known_hosts. bz#2763
* ssh(1): Don't accept junk after "yes" or "no" responses to
hostkey prompts. bz#2803
* sftp(1): Have sftp print a warning about shell cleanliness
when decoding the first packet fails, which is usually caused
by shells polluting stdout of non-interactive startups.
bz#2800
* ssh(1)/sshd(8): Switch timers in packet code from using
wall-clock time to monotonic time, allowing the packet layer
to better function over a clock step and avoiding possible
integer overflows during steps.
* Numerous manual page fixes and improvements.

Distilled upstream log:
- OpenSSH 7.3
- --- Security
* sshd(8): Mitigate a potential denial-of-service attack
against the system's crypt(3) function via sshd(8). An
attacker could send very long passwords that would cause
excessive CPU use in crypt(3). sshd(8) now refuses to accept
password authentication requests of length greater than 1024
characters. Independently reported by Tomas Kuthan (Oracle),
Andres Rojas and Javier Nieto.
* sshd(8): Mitigate timing differences in password
authentication that could be used to discern valid from
invalid account names when long passwords were sent and
particular password hashing algorithms are in use on the
server. CVE-2016-6210, reported by EddieEzra.Harari at
verint.com
* ssh(1), sshd(8): Fix observable timing weakness in the CBC
padding oracle countermeasures. Reported by Jean Paul
Degabriele, Kenny Paterson, Torben Hansen and Martin
Albrecht. Note that CBC ciphers are disabled by default and
only included for legacy compatibility.
* ssh(1), sshd(8): Improve operation ordering of MAC
verification for Encrypt-then-MAC (EtM) mode transport MAC
algorithms to verify the MAC before decrypting any
ciphertext. This removes the possibility of timing
differences leaking facts about the plaintext, though no such
leakage has been observed. Reported by Jean Paul Degabriele,
Kenny Paterson, Torben Hansen and Martin Albrecht.
* sshd(8): (portable only) Ignore PAM environment vars when
UseLogin=yes. If PAM is configured to read user-specified
environment variables and UseLogin=yes in sshd_config, then a
hostile local user may attack /bin/login via LD_PRELOAD or
similar environment variables set via PAM. CVE-2015-8325,
found by Shayan Sadigh.
- --- New Features
* ssh(1): Add a ProxyJump option and corresponding -J
command-line flag to allow simplified indirection through a
one or more SSH bastions or "jump hosts".
* ssh(1): Add an IdentityAgent option to allow specifying
specific agent sockets instead of accepting one from the
environment.
* ssh(1): Allow ExitOnForwardFailure and ClearAllForwardings to
be optionally overridden when using ssh -W. bz#2577
* ssh(1), sshd(8): Implement support for the IUTF8 terminal
mode as per draft-sgtatham-secsh-iutf8-00.
* ssh(1), sshd(8): Add support for additional fixed
Diffie-Hellman 2K, 4K and 8K groups from
draft-ietf-curdle-ssh-kex-sha2-03.
* ssh-keygen(1), ssh(1), sshd(8): support SHA256 and SHA512 RSA
signatures in certificates;
* ssh(1): Add an Include directive for ssh_config(5) files.
* ssh(1): Permit UTF-8 characters in pre-authentication banners
sent from the server. bz#2058
- --- Bugfixes
* ssh(1), sshd(8): Reduce the syslog level of some relatively
common protocol events from LOG_CRIT. bz#2585
* sshd(8): Refuse AuthenticationMethods="" in configurations
and accept AuthenticationMethods=any for the default
behaviour of not requiring multiple authentication. bz#2398
* sshd(8): Remove obsolete and misleading "POSSIBLE BREAK-IN
ATTEMPT!" message when forward and reverse DNS don't match.
bz#2585
* ssh(1): Close ControlPersist background process stderr except
in debug mode or when logging to syslog. bz#1988
* misc: Make PROTOCOL description for
direct-streamlocal@openssh.com channel open messages match
deployed code. bz#2529
* ssh(1): Deduplicate LocalForward and RemoteForward entries to
fix failures when both ExitOnForwardFailure and hostname
canonicalisation are enabled. bz#2562
* sshd(8): Remove fallback from moduli to obsolete "primes"
file that was deprecated in 2001. bz#2559.
* sshd_config(5): Correct description of UseDNS: it affects ssh
hostname processing for authorized_keys, not known_hosts;
bz#2554
* ssh(1): Fix authentication using lone certificate keys in an
agent without corresponding private keys on the filesystem.
bz#2550
* sshd(8): Send ClientAliveInterval pings when a time-based
RekeyLimit is set; previously keepalive packets were not
being sent. bz#2252
- --- Portability
* ssh(1), sshd(8): Fix compilation by automatically disabling
ciphers not supported by OpenSSL. bz#2466
* misc: Fix compilation failures on some versions of AIX's
compiler related to the definition of the VA_COPY macro.
bz#2589
* sshd(8): Whitelist more architectures to enable the
seccomp-bpf sandbox. bz#2590
* ssh-agent(1), sftp-server(8): Disable process tracing on
Solaris using setpflags(__PROC_PROTECT, ...). bz#2584
* sshd(8): On Solaris, don't call Solaris setproject() with
UsePAM=yes it's PAM's responsibility. bz#2425
- OpenSSH 7.4
- --- Potentially-incompatible changes
* ssh(1): Remove 3des-cbc from the client's default proposal.
64-bit block ciphers are not safe in 2016 and we don't want
to wait until attacks like SWEET32 are extended to SSH. As
3des-cbc was the only mandatory cipher in the SSH RFCs, this
may cause problems connecting to older devices using the
default configuration, but it's highly likely that such
devices already need explicit configuration for key exchange
and hostkey algorithms already anyway.
* sshd(8): Remove support for pre-authentication compression.
Doing compression early in the protocol probably seemed
reasonable in the 1990s, but today it's clearly a bad idea in
terms of both cryptography (cf. multiple compression oracle
attacks in TLS) and attack surface. Pre-auth compression
support has been disabled by default for >10 years. Support
remains in the client.
* ssh-agent will refuse to load PKCS#11 modules outside a
whitelist of trusted paths by default. The path whitelist may
be specified at run-time.
* sshd(8): When a forced-command appears in both a certificate
and an authorized keys/principals command= restriction, sshd
will now refuse to accept the certificate unless they are
identical. The previous (documented) behaviour of having the
certificate forced-command override the other could be a bit
confusing and error-prone.
* sshd(8): Remove the UseLogin configuration directive and
support for having /bin/login manage login sessions.
- --- Security
* ssh-agent(1): Will now refuse to load PKCS#11 modules from
paths outside a trusted whitelist (run-time configurable).
Requests to load modules could be passed via agent forwarding
and an attacker could attempt to load a hostile PKCS#11
module across the forwarded agent channel: PKCS#11 modules
are shared libraries, so this would result in code execution
on the system running the ssh-agent if the attacker has
control of the forwarded agent-socket (on the host running
the sshd server) and the ability to write to the filesystem
of the host running ssh-agent (usually the host running the
ssh client). Reported by Jann Horn of Project Zero.
* sshd(8): When privilege separation is disabled, forwarded
Unix- domain sockets would be created by sshd(8) with the
privileges of 'root' instead of the authenticated user. This
release refuses Unix-domain socket forwarding when privilege
separation is disabled (Privilege separation has been enabled
by default for 14 years). Reported by Jann Horn of Project
Zero.
* sshd(8): Avoid theoretical leak of host private key material
to privilege-separated child processes via realloc() when
reading keys. No such leak was observed in practice for
normal-sized keys, nor does a leak to the child processes
directly expose key material to unprivileged users. Reported
by Jann Horn of Project Zero.
* sshd(8): The shared memory manager used by pre-authentication
compression support had a bounds checks that could be elided
by some optimising compilers. Additionally, this memory
manager was incorrectly accessible when pre-authentication
compression was disabled. This could potentially allow
attacks against the privileged monitor process from the
sandboxed privilege-separation process (a compromise of the
latter would be required first). This release removes
support for pre-authentication compression from sshd(8).
Reported by Guido Vranken using the Stack unstable
optimisation identification tool
(http://css.csail.mit.edu/stack/)
* sshd(8): Fix denial-of-service condition where an attacker
who sends multiple KEXINIT messages may consume up to 128MB
per connection. Reported by Shi Lei of Gear Team, Qihoo 360.
* sshd(8): Validate address ranges for AllowUser and DenyUsers
directives at configuration load time and refuse to accept
invalid ones. It was previously possible to specify invalid
CIDR address ranges (e.g. user@127.1.2.3/55) and these would
always match, possibly resulting in granting access where it
was not intended. Reported by Laurence Parry.
- --- New Features
* ssh(1): Add a proxy multiplexing mode to ssh(1) inspired by
the version in PuTTY by Simon Tatham. This allows a
multiplexing client to communicate with the master process
using a subset of the SSH packet and channels protocol over a
Unix-domain socket, with the main process acting as a proxy
that translates channel IDs, etc. This allows multiplexing
mode to run on systems that lack file- descriptor passing
(used by current multiplexing code) and potentially, in
conjunction with Unix-domain socket forwarding, with the
client and multiplexing master process on different machines.
Multiplexing proxy mode may be invoked using "ssh -O proxy
..."
* sshd(8): Add a sshd_config DisableForwarding option that
disables X11, agent, TCP, tunnel and Unix domain socket
forwarding, as well as anything else we might implement in
the future. Like the 'restrict' authorized_keys flag, this is
intended to be a simple and future-proof way of restricting
an account.
* sshd(8), ssh(1): Support the "curve25519-sha256" key exchange
method. This is identical to the currently-supported method
named "curve25519-sha256@libssh.org".
* sshd(8): Improve handling of SIGHUP by checking to see if
sshd is already daemonised at startup and skipping the call
to daemon(3) if it is. This ensures that a SIGHUP restart of
sshd(8) will retain the same process-ID as the initial
execution. sshd(8) will also now unlink the PidFile prior to
SIGHUP restart and re-create it after a successful restart,
rather than leaving a stale file in the case of a
configuration error. bz#2641
* sshd(8): Allow ClientAliveInterval and ClientAliveCountMax
directives to appear in sshd_config Match blocks.
* sshd(8): Add %-escapes to AuthorizedPrincipalsCommand to
match those supported by AuthorizedKeysCommand (key, key
type, fingerprint, etc.) and a few more to provide access to
the contents of the certificate being offered.
* Added regression tests for string matching, address matching
and string sanitisation functions.
* Improved the key exchange fuzzer harness.
- --- Bugfixes
* ssh(1): Allow IdentityFile to successfully load and use
certificates that have no corresponding bare public key.
bz#2617 certificate id_rsa-cert.pub (and no id_rsa.pub).
* ssh(1): Fix public key authentication when multiple
authentication is in use and publickey is not just the first
method attempted. bz#2642
* regress: Allow the PuTTY interop tests to run unattended.
bz#2639
* ssh-agent(1), ssh(1): improve reporting when attempting to
load keys from PKCS#11 tokens with fewer useless log messages
and more detail in debug messages. bz#2610
* ssh(1): When tearing down ControlMaster connections, don't
pollute stderr when LogLevel=quiet.
* sftp(1): On ^Z wait for underlying ssh(1) to suspend before
suspending sftp(1) to ensure that ssh(1) restores the
terminal mode correctly if suspended during a password
prompt.
* ssh(1): Avoid busy-wait when ssh(1) is suspended during a
password prompt.
* ssh(1), sshd(8): Correctly report errors during sending of
ext- info messages.
* sshd(8): fix NULL-deref crash if sshd(8) received an out-of-
sequence NEWKEYS message.
* sshd(8): Correct list of supported signature algorithms sent
in the server-sig-algs extension. bz#2547
* sshd(8): Fix sending ext_info message if privsep is disabled.
* sshd(8): more strictly enforce the expected ordering of
privilege separation monitor calls used for authentication
and allow them only when their respective authentication
methods are enabled in the configuration
* sshd(8): Fix uninitialised optlen in getsockopt() call;
harmless on Unix/BSD but potentially crashy on Cygwin.
* Fix false positive reports caused by explicit_bzero(3) not
being recognised as a memory initialiser when compiled with
- fsanitize-memory.
* sshd_config(5): Use 2001:db8::/32, the official IPv6 subnet
for configuration examples.
- --- Portability
* On environments configured with Turkish locales, fall back to
the C/POSIX locale to avoid errors in configuration parsing
caused by that locale's unique handling of the letters 'i'
and 'I'. bz#2643
* sftp-server(8), ssh-agent(1): Deny ptrace on OS X using
ptrace(PT_DENY_ATTACH, ..)
* ssh(1), sshd(8): Unbreak AES-CTR ciphers on old (~0.9.8)
OpenSSL.
* Fix compilation for libcrypto compiled without RIPEMD160
support.
* contrib: Add a gnome-ssh-askpass3 with GTK+3 support. bz#2640
* sshd(8): Improve PRNG reseeding across privilege separation
and force libcrypto to obtain a high-quality seed before
chroot or sandboxing.
* All: Explicitly test for broken strnvis. NetBSD added an
strnvis and unfortunately made it incompatible with the
existing one in OpenBSD and Linux's libbsd (the former having
existed for over ten years). Try to detect this mess, and
assume the only safe option if we're cross compiling.
- OpenSSH 7.5
- --- Potentially-incompatible changes
* This release deprecates the sshd_config
UsePrivilegeSeparation option, thereby making privilege
separation mandatory. Privilege separation has been on by
default for almost 15 years and sandboxing has been on by
default for almost the last five.
* The format of several log messages emitted by the packet code
has changed to include additional information about the user
and their authentication state. Software that monitors
ssh/sshd logs may need to account for these changes. For
example:
Connection closed by user x 1.1.1.1 port 1234 [preauth]
Connection closed by authenticating user x 10.1.1.1 port 1234
[preauth] Connection closed by invalid user x 1.1.1.1 port
1234 [preauth]
Affected messages include connection closure, timeout, remote
disconnection, negotiation failure and some other fatal
messages generated by the packet code.
* [Portable OpenSSH only] This version removes support for
building against OpenSSL versions prior to 1.0.1. OpenSSL
stopped supporting versions prior to 1.0.1 over 12 months ago
(i.e. they no longer receive fixes for security bugs).
- --- Security
* ssh(1), sshd(8): Fix weakness in CBC padding oracle
countermeasures that allowed a variant of the attack fixed in
OpenSSH 7.3 to proceed. Note that the OpenSSH client
disables CBC ciphers by default, sshd offers them as
lowest-preference options and will remove them by default
entriely in the next release. Reported by Jean Paul
Degabriele, Kenny Paterson, Martin Albrecht and Torben Hansen
of Royal Holloway, University of London.
* sftp-client(1): [portable OpenSSH only] On Cygwin, a client
making a recursive file transfer could be maniuplated by a
hostile server to perform a path-traversal attack. creating
or modifying files outside of the intended target directory.
Reported by Jann Horn of Google Project Zero.
- --- New Features
* ssh(1), sshd(8): Support "=-" syntax to easily remove methods
from algorithm lists, e.g. Ciphers=-*cbc. bz#2671
- --- Bugfixes
* sshd(1): Fix NULL dereference crash when key exchange start
messages are sent out of sequence.
* ssh(1), sshd(8): Allow form-feed characters to appear in
configuration files.
* sshd(8): Fix regression in OpenSSH 7.4 support for the
server-sig-algs extension, where SHA2 RSA signature methods
were not being correctly advertised. bz#2680
* ssh(1), ssh-keygen(1): Fix a number of case-sensitivity bugs
in known_hosts processing. bz#2591 bz#2685
* ssh(1): Allow ssh to use certificates accompanied by a
private key file but no corresponding plain *.pub public key.
bz#2617
* ssh(1): When updating hostkeys using the UpdateHostKeys
option, accept RSA keys if HostkeyAlgorithms contains any RSA
keytype. Previously, ssh could ignore RSA keys when only the
ssh-rsa-sha2-* methods were enabled in HostkeyAlgorithms and
not the old ssh-rsa method. bz#2650
* ssh(1): Detect and report excessively long configuration file
lines. bz#2651
* Merge a number of fixes found by Coverity and reported via
Redhat and FreeBSD. Includes fixes for some memory and file
descriptor leaks in error paths. bz#2687
* ssh-keyscan(1): Correctly hash hosts with a port number.
bz#2692
* ssh(1), sshd(8): When logging long messages to stderr, don't
truncate "\r\n" if the length of the message exceeds the
buffer. bz#2688
* ssh(1): Fully quote [host]:port in generated ProxyJump/-J
command- line; avoid confusion over IPv6 addresses and shells
that treat square bracket characters specially.
* ssh-keygen(1): Fix corruption of known_hosts when running
"ssh-keygen -H" on a known_hosts containing already-hashed
entries.
* Fix various fallout and sharp edges caused by removing SSH
protocol 1 support from the server, including the server
banner string being incorrectly terminated with only \n
(instead of \r\n), confusing error messages from ssh-keyscan
bz#2583 and a segfault in sshd if protocol v.1 was enabled
for the client and sshd_config contained references to legacy
keys bz#2686.
* ssh(1), sshd(8): Free fd_set on connection timeout. bz#2683
* sshd(8): Fix Unix domain socket forwarding for root
(regression in OpenSSH 7.4).
* sftp(1): Fix division by zero crash in "df" output when
server returns zero total filesystem blocks/inodes.
* ssh(1), ssh-add(1), ssh-keygen(1), sshd(8): Translate OpenSSL
errors encountered during key loading to more meaningful
error codes. bz#2522 bz#2523
* ssh-keygen(1): Sanitise escape sequences in key comments sent
to printf but preserve valid UTF-8 when the locale supports
it; bz#2520
* ssh(1), sshd(8): Return reason for port forwarding failures
where feasible rather than always "administratively
prohibited". bz#2674
* sshd(8): Fix deadlock when AuthorizedKeysCommand or
AuthorizedPrincipalsCommand produces a lot of output and a
key is matched early. bz#2655
* Regression tests: several reliability fixes. bz#2654 bz#2658
bz#2659
* ssh(1): Fix typo in ~C error message for bad port forward
cancellation. bz#2672
* ssh(1): Show a useful error message when included config
files can't be opened; bz#2653
* sshd(8): Make sshd set GSSAPIStrictAcceptorCheck=yes as the
manual page (previously incorrectly) advertised. bz#2637
* sshd_config(5): Repair accidentally-deleted mention of %k
token in AuthorizedKeysCommand; bz#2656
* sshd(8): Remove vestiges of previously removed LOGIN_PROGRAM;
bz#2665
* ssh-agent(1): Relax PKCS#11 whitelist to include libexec and
common 32-bit compatibility library directories.
* sftp-client(1): Fix non-exploitable integer overflow in
SSH2_FXP_NAME response handling.
* ssh-agent(1): Fix regression in 7.4 of deleting
PKCS#11-hosted keys. It was not possible to delete them
except by specifying their full physical path. bz#2682
- --- Portability
* sshd(8): Avoid sandbox errors for Linux S390 systems using an
ICA crypto coprocessor.
* sshd(8): Fix non-exploitable weakness in seccomp-bpf sandbox
arg inspection.
* ssh(1): Fix X11 forwarding on OSX where X11 was being started
by launchd. bz#2341
* ssh-keygen(1), ssh(1), sftp(1): Fix output truncation for
various that contain non-printable characters where the
codeset in use is ASCII.
* build: Fix builds that attempt to link a kerberised libldns.
bz#2603
* build: Fix compilation problems caused by unconditionally
defining _XOPEN_SOURCE in wide character detection.
* sshd(8): Fix sandbox violations for clock_gettime VSDO
syscall fallback on some Linux/X32 kernels. bz#2142
- OpenSSH 7.6
- --- Potentially-incompatible changes
This release includes a number of changes that may affect
existing configurations:
* ssh(1): delete SSH protocol version 1 support, associated
configuration options and documentation.
* ssh(1)/sshd(8): remove support for the hmac-ripemd160 MAC.
* ssh(1)/sshd(8): remove support for the arcfour, blowfish and
CAST ciphers.
* Refuse RSA keys <1024 bits in length and improve reporting
for keys that do not meet this requirement.
* ssh(1): do not offer CBC ciphers by default.
- --- Security
* sftp-server(8): in read-only mode, sftp-server was
incorrectly permitting creation of zero-length files.
Reported by Michal Zalewski.
- --- New Features
* ssh(1): add RemoteCommand option to specify a command in the
ssh config file instead of giving it on the client's command
line. This allows the configuration file to specify the
command that will be executed on the remote host.
* sshd(8): add ExposeAuthInfo option that enables writing
details of the authentication methods used (including public
keys where applicable) to a file that is exposed via a
$SSH_USER_AUTH environment variable in the subsequent
session.
* ssh(1): add support for reverse dynamic forwarding. In this
mode, ssh will act as a SOCKS4/5 proxy and forward
connections to destinations requested by the remote SOCKS
client. This mode is requested using extended syntax for the
- R and RemoteForward options and, because it is implemented
solely at the client, does not require the server be updated
to be supported.
* sshd(8): allow LogLevel directive in sshd_config Match
blocks; bz#2717
* ssh-keygen(1): allow inclusion of arbitrary string or flag
certificate extensions and critical options.
* ssh-keygen(1): allow ssh-keygen to use a key held in
ssh-agent as a CA when signing certificates. bz#2377
* ssh(1)/sshd(8): allow IPQoS=none in ssh/sshd to not set an
explicit ToS/DSCP value and just use the operating system
default.
* ssh-add(1): added -q option to make ssh-add quiet on success.
* ssh(1): expand the StrictHostKeyChecking option with two new
settings. The first "accept-new" will automatically accept
hitherto-unseen keys but will refuse connections for changed
or invalid hostkeys. This is a safer subset of the current
behaviour of StrictHostKeyChecking=no. The second setting
"off", is a synonym for the current behaviour of
StrictHostKeyChecking=no: accept new host keys, and continue
connection for hosts with incorrect hostkeys. A future
release will change the meaning of StrictHostKeyChecking=no
to the behaviour of "accept-new". bz#2400
* ssh(1): add SyslogFacility option to ssh(1) matching the
equivalent option in sshd(8). bz#2705
- --- Bugfixes
* ssh(1): use HostKeyAlias if specified instead of hostname for
matching host certificate principal names; bz#2728
* sftp(1): implement sorting for globbed ls; bz#2649
* ssh(1): add a user@host prefix to client's "Permission
denied" messages, useful in particular when using "stacked"
connections (e.g. ssh -J) where it's not clear which host is
denying. bz#2720
* ssh(1): accept unknown EXT_INFO extension values that contain
\0 characters. These are legal, but would previously cause
fatal connection errors if received.
* ssh(1)/sshd(8): repair compression statistics printed at
connection exit
* sftp(1): print '?' instead of incorrect link count (that the
protocol doesn't provide) for remote listings. bz#2710
* ssh(1): return failure rather than fatal() for more cases
during session multiplexing negotiations. Causes the session
to fall back to a non-mux connection if they occur. bz#2707
* ssh(1): mention that the server may send debug messages to
explain public key authentication problems under some
circumstances; bz#2709
* Translate OpenSSL error codes to better report incorrect
passphrase errors when loading private keys; bz#2699
* sshd(8): adjust compatibility patterns for WinSCP to
correctly identify versions that implement only the legacy DH
group exchange scheme. bz#2748
* ssh(1): print the "Killed by signal 1" message only at
LogLevel verbose so that it is not shown at the default
level; prevents it from appearing during ssh -J and
equivalent ProxyCommand configs. bz#1906, bz#2744
* ssh-keygen(1): when generating all hostkeys (ssh-keygen -A),
clobber existing keys if they exist but are zero length.
zero-length keys could previously be made if ssh-keygen
failed or was interrupted part way through generating them.
bz#2561
* ssh(1): fix pledge(2) violation in the escape sequence "~&"
used to place the current session in the background.
* ssh-keyscan(1): avoid double-close() on file descriptors;
bz#2734
* sshd(8): avoid reliance on shared use of pointers shared
between monitor and child sshd processes. bz#2704
* sshd_config(8): document available AuthenticationMethods;
bz#2453
* ssh(1): avoid truncation in some login prompts; bz#2768
* sshd(8): Fix various compilations failures, inc bz#2767
* ssh(1): make "--" before the hostname terminate argument
processing after the hostname too.
* ssh-keygen(1): switch from aes256-cbc to aes256-ctr for
encrypting new-style private keys. Fixes problems related to
private key handling for no-OpenSSL builds. bz#2754
* ssh(1): warn and do not attempt to use keys when the public
and private halves do not match. bz#2737
* sftp(1): don't print verbose error message when ssh
disconnects from under sftp. bz#2750
* sshd(8): fix keepalive scheduling problem: activity on a
forwarded port from preventing the keepalive from being sent;
bz#2756
* sshd(8): when started without root privileges, don't require
the privilege separation user or path to exist. Makes running
the regression tests easier without touching the filesystem.
* Make integrity.sh regression tests more robust against
timeouts. bz#2658
* ssh(1)/sshd(8): correctness fix for channels implementation:
accept channel IDs greater than 0x7FFFFFFF.
- --- Portability
* sshd(9): drop two more privileges in the Solaris sandbox:
PRIV_DAX_ACCESS and PRIV_SYS_IB_INFO; bz#2723
* sshd(8): expose list of completed authentication methods to
PAM via the SSH_AUTH_INFO_0 PAM environment variable. bz#2408
* ssh(1)/sshd(8): fix several problems in the tun/tap
forwarding code, mostly to do with host/network byte order
confusion. bz#2735
* Add --with-cflags-after and --with-ldflags-after configure
flags to allow setting CFLAGS/LDFLAGS after configure has
completed. These are useful for setting sanitiser/fuzzing
options that may interfere with configure's operation.
* sshd(8): avoid Linux seccomp violations on ppc64le over the
socketcall syscall.
* Fix use of ldns when using ldns-config; bz#2697
* configure: set cache variables when cross-compiling. The
cross- compiling fallback message was saying it assumed the
test passed, but it wasn't actually set the cache variables
and this would cause later tests to fail.
* Add clang libFuzzer harnesses for public key parsing and
signature verification.

- upgrade to 7.2p2
upstream package without any SUSE patches
Distilled upstream log:
- OpenSSH 6.7
Potentially-incompatible changes:
* sshd(8): The default set of ciphers and MACs has been
altered to remove unsafe algorithms. In particular, CBC
ciphers and arcfour* are disabled by default.
The full set of algorithms remains available if configured
explicitly via the Ciphers and MACs sshd_config options.
* sshd(8): Support for tcpwrappers/libwrap has been removed.
* OpenSSH 6.5 and 6.6 have a bug that causes ~0.2% of
connections using the curve25519-sha256@libssh.org KEX
exchange method to fail when connecting with something that
implements the specification correctly. OpenSSH 6.7 disables
this KEX method when speaking to one of the affected
versions.
New Features:
* ssh(1), sshd(8): Add support for Unix domain socket
forwarding. A remote TCP port may be forwarded to a local
Unix domain socket and vice versa or both ends may be a Unix
domain socket.
* ssh(1), ssh-keygen(1): Add support for SSHFP DNS records for
ED25519 key types.
* sftp(1): Allow resumption of interrupted uploads.
* ssh(1): When rekeying, skip file/DNS lookups of the hostkey
if it is the same as the one sent during initial key exchange
* sshd(8): Allow explicit ::1 and 127.0.0.1 forwarding bind
addresses when GatewayPorts=no; allows client to choose
address family
* sshd(8): Add a sshd_config PermitUserRC option to control
whether ~/.ssh/rc is executed, mirroring the no-user-rc
authorized_keys option
* ssh(1): Add a %C escape sequence for LocalCommand and
ControlPath that expands to a unique identifer based on a
hash of the tuple of (local host, remote user, hostname,
port). Helps avoid exceeding miserly pathname limits for Unix
domain sockets in multiplexing control paths
* sshd(8): Make the "Too many authentication failures" message
include the user, source address, port and protocol in a
format similar to the authentication success / failure
messages
Bugfixes:
* sshd(8): Fix remote forwarding with the same listen port but
different listen address.
* ssh(1): Fix inverted test that caused PKCS#11 keys that were
explicitly listed in ssh_config or on the commandline not to
be preferred.
* ssh-keygen(1): Fix bug in KRL generation: multiple
consecutive revoked certificate serial number ranges could be
serialised to an invalid format. Readers of a broken KRL
caused by this bug will fail closed, so no
should-have-been-revoked key will be accepted.
* ssh(1): Reflect stdio-forward ("ssh -W host:port ...")
failures in exit status. Previously we were always returning 0
* ssh(1), ssh-keygen(1): Make Ed25519 keys' title fit properly
in the randomart border
* ssh-agent(1): Only cleanup agent socket in the main agent
process and not in any subprocesses it may have started (e.g.
forked askpass). Fixes agent sockets being zapped when
askpass processes fatal()
* ssh-add(1): Make stdout line-buffered; saves partial output
getting lost when ssh-add fatal()s part-way through (e.g.
when listing keys from an agent that supports key types that
ssh-add doesn't)
* ssh-keygen(1): When hashing or removing hosts, don't choke on
@revoked markers and don't remove @cert-authority markers
* ssh(1): Don't fatal when hostname canonicalisation fails and
a ProxyCommand is in use; continue and allow the ProxyCommand
to connect anyway (e.g. to a host with a name outside the DNS
behind a bastion)
* scp(1): When copying local->remote fails during read, don't
send uninitialised heap to the remote end.
* sftp(1): Fix fatal "el_insertstr failed" errors when
tab-completing filenames with a single quote char somewhere
in the string
* ssh-keyscan(1): Scan for Ed25519 keys by default.
* ssh(1): When using VerifyHostKeyDNS with a DNSSEC resolver,
down-convert any certificate keys to plain keys and attempt
SSHFP resolution. Prevents a server from skipping SSHFP
lookup and forcing a new-hostkey dialog by offering only
certificate keys.
- OpenSSH 6.8
Potentially-incompatible changes:
* sshd(8): UseDNS now defaults to 'no'. Configurations that
match against the client host name (via sshd_config or
authorized_keys) may need to re-enable it or convert to
matching against addresses.
New Features:
* Add FingerprintHash option to ssh(1) and sshd(8), and
equivalent command-line flags to the other tools to control
algorithm used for key fingerprints. The default changes from
MD5 to SHA256 and format from hex to base64.
Fingerprints now have the hash algorithm prepended. An
example of the new format:
SHA256:mVPwvezndPv/ARoIadVY98vAC0g+P/5633yTC4d/wXE Please
note that visual host keys will also be different.
* ssh(1), sshd(8): Experimental host key rotation support. Add
a protocol extension for a server to inform a client of all
its available host keys after authentication has completed.
The client may record the keys in known_hosts, allowing it to
upgrade to better host key algorithms and a server to
gracefully rotate its keys.
The client side of this is controlled by a UpdateHostkeys
config option (default off).
* ssh(1): Add a ssh_config HostbasedKeyType option to control
which host public key types are tried during host-based
authentication.
* ssh(1), sshd(8): fix connection-killing host key mismatch
errors when sshd offers multiple ECDSA keys of different
lengths.
* ssh(1): when host name canonicalisation is enabled, try to
parse host names as addresses before looking them up for
canonicalisation. fixes bz#2074 and avoiding needless DNS
lookups in some cases.
* ssh-keygen(1), sshd(8): Key Revocation Lists (KRLs) no longer
require OpenSSH to be compiled with OpenSSL support.
* ssh(1), ssh-keysign(8): Make ed25519 keys work for host based
authentication.
* sshd(8): SSH protocol v.1 workaround for the Meyer, et al,
Bleichenbacher Side Channel Attack. Fake up a bignum key
before RSA decryption.
* sshd(8): Remember which public keys have been used for
authentication and refuse to accept previously-used keys.
This allows AuthenticationMethods=publickey,publickey to
require that users authenticate using two _different_ public
keys.
* sshd(8): add sshd_config HostbasedAcceptedKeyTypes and
PubkeyAcceptedKeyTypes options to allow sshd to control what
public key types will be accepted. Currently defaults to all.
* sshd(8): Don't count partial authentication success as a
failure against MaxAuthTries.
* ssh(1): Add RevokedHostKeys option for the client to allow
text-file or KRL-based revocation of host keys.
* ssh-keygen(1), sshd(8): Permit KRLs that revoke certificates
by serial number or key ID without scoping to a particular
CA.
* ssh(1): Add a "Match canonical" criteria that allows
ssh_config Match blocks to trigger only in the second config
pass.
* ssh(1): Add a -G option to ssh that causes it to parse its
configuration and dump the result to stdout, similar to
"sshd -T".
* ssh(1): Allow Match criteria to be negated.
E.g. "Match !host".
* The regression test suite has been extended to cover more
OpenSSH features. The unit tests have been expanded and now
cover key exchange.
Bugfixes:
* ssh-keyscan(1): ssh-keyscan has been made much more robust
again servers that hang or violate the SSH protocol.
* ssh(1), ssh-keygen(1): Fix regression: Key path names were
being lost as comment fields.
* ssh(1): Allow ssh_config Port options set in the second
config parse phase to be applied (they were being ignored).
* ssh(1): Tweak config re-parsing with host canonicalisation - make
the second pass through the config files always run when host name
canonicalisation is enabled (and not whenever the host name
changes)
* ssh(1): Fix passing of wildcard forward bind addresses when
connection multiplexing is in use
* ssh-keygen(1): Fix broken private key conversion from
non-OpenSSH formats.
* ssh-keygen(1): Fix KRL generation bug when multiple CAs are
in use.
* Various fixes to manual pages
- OpenSSH 6.9
Security:
* ssh(1): when forwarding X11 connections with
ForwardX11Trusted=no, connections made after
ForwardX11Timeout expired could be permitted and no longer
subject to XSECURITY restrictions because of an ineffective
timeout check in ssh(1) coupled with "fail open" behaviour in
the X11 server when clients attempted connections with
expired credentials. This problem was reported by Jann Horn.
* ssh-agent(1): fix weakness of agent locking (ssh-add -x) to
password guessing by implementing an increasing failure
delay, storing a salted hash of the password rather than the
password itself and using a timing-safe comparison function
for verifying unlock attempts. This problem was reported by
Ryan Castellucci.
New Features:
* ssh(1), sshd(8): promote chacha20-poly1305@openssh.com to be
the default cipher
* sshd(8): support admin-specified arguments to
AuthorizedKeysCommand
* sshd(8): add AuthorizedPrincipalsCommand that allows
retrieving authorized principals information from a
subprocess rather than a file.
* ssh(1), ssh-add(1): support PKCS#11 devices with external PIN
entry devices
* sshd(8): allow GSSAPI host credential check to be relaxed for
multihomed hosts via GSSAPIStrictAcceptorCheck option
* ssh-keygen(1): support "ssh-keygen -lF hostname" to search
known_hosts and print key hashes rather than full keys.
* ssh-agent(1): add -D flag to leave ssh-agent in foreground
without enabling debug mode
Bugfixes:
* ssh(1), sshd(8): deprecate legacy
SSH2_MSG_KEX_DH_GEX_REQUEST_OLD message and do not try to use
it against some 3rd-party SSH implementations that use it
(older PuTTY, WinSCP).
* Many fixes for problems caused by compile-time deactivation
of SSH1 support (including bz#2369)
* ssh(1), sshd(8): cap DH-GEX group size at 4Kbits for Cisco
implementations as some would fail when attempting to use
group sizes >4K
* ssh(1): fix out-of-bound read in EscapeChar configuration
option parsing
* sshd(8): fix application of PermitTunnel, LoginGraceTime,
AuthenticationMethods and StreamLocalBindMask options in
Match blocks
* ssh(1), sshd(8): improve disconnection message on TCP reset;
bz#2257
* ssh(1): remove failed remote forwards established by
muliplexing from the list of active forwards
* sshd(8): make parsing of authorized_keys "environment="
options independent of PermitUserEnv being enabled
* sshd(8): fix post-auth crash with permitopen=none
* ssh(1), ssh-add(1), ssh-keygen(1): allow new-format private
keys to be encrypted with AEAD ciphers
* ssh(1): allow ListenAddress, Port and AddressFamily
configuration options to appear in any order
* sshd(8): check for and reject missing arguments for
VersionAddendum and ForceCommand
* ssh(1), sshd(8): don't treat unknown certificate extensions
as fatal
* ssh-keygen(1): make stdout and stderr output consistent
* ssh(1): mention missing DISPLAY environment in debug log when
X11 forwarding requested
* sshd(8): correctly record login when UseLogin is set
* sshd(8): Add some missing options to sshd -T output and fix
output of VersionAddendum and HostCertificate. bz#2346
* Document and improve consistency of options that accept a
"none" argument" TrustedUserCAKeys, RevokedKeys (bz#2382),
AuthorizedPrincipalsFile (bz#2288)
* ssh(1): include remote username in debug output
* sshd(8): avoid compatibility problem with some versions of
Tera Term, which would crash when they received the hostkeys
notification message (hostkeys-00@openssh.com)
* sshd(8): mention ssh-keygen -E as useful when comparing
legacy MD5 host key fingerprints
* ssh(1): clarify pseudo-terminal request behaviour and use
make manual language consistent
* ssh(1): document that the TERM environment variable is not
subject to SendEnv and AcceptEnv
- OpenSSH 7.0:
This focuses primarily on deprecating weak, legacy and/or
unsafe cryptography.
Security:
* sshd(8): OpenSSH 6.8 and 6.9 incorrectly set TTYs to be
world- writable. Local attackers may be able to write
arbitrary messages to logged-in users, including terminal
escape sequences. Reported by Nikolay Edigaryev.
* sshd(8): Portable OpenSSH only: Fixed a privilege separation
weakness related to PAM support. Attackers who could
successfully compromise the pre-authentication process for
remote code execution and who had valid credentials on the
host could impersonate other users. Reported by Moritz
Jodeit.
* sshd(8): Portable OpenSSH only: Fixed a use-after-free bug
related to PAM support that was reachable by attackers who
could compromise the pre-authentication process for remote
code execution. Also reported by Moritz Jodeit.
* sshd(8): fix circumvention of MaxAuthTries using keyboard-
interactive authentication. By specifying a long, repeating
keyboard-interactive "devices" string, an attacker could
request the same authentication method be tried thousands of
times in a single pass. The LoginGraceTime timeout in sshd(8)
and any authentication failure delays implemented by the
authentication mechanism itself were still applied. Found by
Kingcope.
Potentially-incompatible Changes:
* Support for the legacy SSH version 1 protocol is disabled by
default at compile time.
* Support for the 1024-bit diffie-hellman-group1-sha1 key
exchange is disabled by default at run-time. It may be
re-enabled using the instructions in README.legacy or
http://www.openssh.com/legacy.html
* Support for ssh-dss, ssh-dss-cert-* host and user keys is
disabled by default at run-time. These may be re-enabled
using the instructions at http://www.openssh.com/legacy.html
* Support for the legacy v00 cert format has been removed.
* The default for the sshd_config(5) PermitRootLogin option has
changed from "yes" to "prohibit-password".
* PermitRootLogin=without-password/prohibit-password now bans
all interactive authentication methods, allowing only
public-key, hostbased and GSSAPI authentication (previously
it permitted keyboard-interactive and password-less
authentication if those were enabled).
New Features:
* ssh_config(5): add PubkeyAcceptedKeyTypes option to control
which public key types are available for user authentication.
* sshd_config(5): add HostKeyAlgorithms option to control which
public key types are offered for host authentications.
* ssh(1), sshd(8): extend Ciphers, MACs, KexAlgorithms,
HostKeyAlgorithms, PubkeyAcceptedKeyTypes and
HostbasedKeyTypes options to allow appending to the default
set of algorithms instead of replacing it. Options may now be
prefixed with a '+' to append to the default, e.g.
"HostKeyAlgorithms=+ssh-dss".
* sshd_config(5): PermitRootLogin now accepts an argument of
'prohibit-password' as a less-ambiguous synonym of 'without-
password'.
Bugfixes:
* ssh(1), sshd(8): add compatability workarounds for Cisco and
more PuTTY versions.
* Fix some omissions and errors in the PROTOCOL and
PROTOCOL.mux documentation relating to Unix domain socket
forwarding
* ssh(1): Improve the ssh(1) manual page to include a better
description of Unix domain socket forwarding
* ssh(1), ssh-agent(1): skip uninitialised PKCS#11 slots,
fixing failures to load keys when they are present.
* ssh(1), ssh-agent(1): do not ignore PKCS#11 hosted keys that
wth empty CKA_ID
* sshd(8): clarify documentation for UseDNS option
- OpenSSH 7.1:
Security:
* sshd(8): OpenSSH 7.0 contained a logic error in
PermitRootLogin= prohibit-password/without-password that
could, depending on compile-time configuration, permit
password authentication to root while preventing other forms
of authentication. This problem was reported by Mantas
Mikulenas.
Bugfixes:
* ssh(1), sshd(8): add compatability workarounds for FuTTY
* ssh(1), sshd(8): refine compatability workarounds for WinSCP
* Fix a number of memory faults (double-free, free of
uninitialised memory, etc) in ssh(1) and ssh-keygen(1).
Reported by Mateusz Kocielski.
- OpenSSH 7.1p2:
* SECURITY: ssh(1): The OpenSSH client code between 5.4 and 7.1
contains experimential support for resuming SSH-connections
(roaming).
The matching server code has never been shipped, but the
client code was enabled by default and could be tricked by a
malicious server into leaking client memory to the server,
including private client user keys.
The authentication of the server host key prevents
exploitation by a man-in-the-middle, so this information leak
is restricted to connections to malicious or compromised
servers.
MITIGATION: For OpenSSH >= 5.4 the vulnerable code in the
client can be completely disabled by adding 'UseRoaming no'
to the gobal ssh_config(5) file, or to user configuration in
~/.ssh/config, or by passing -oUseRoaming=no on the command
line.
PATCH: See below for a patch to disable this feature
(Disabling Roaming in the Source Code).
This problem was reported by the Qualys Security Advisory
team.
* SECURITY: Eliminate the fallback from untrusted
X11-forwarding to trusted forwarding for cases when the X
server disables the SECURITY extension. Reported by Thomas
Hoger.
* SECURITY: Fix an out of-bound read access in the packet
handling code. Reported by Ben Hawkes.
* PROTOCOL: Correctly interpret the 'first_kex_follows' option
during the intial key exchange. Reported by Matt Johnston.
* Further use of explicit_bzero has been added in various
buffer handling code paths to guard against compilers
aggressively doing dead-store removal.
Potentially-incompatible changes:
* This release disables a number of legacy cryptographic
algorithms by default in ssh:
+ Several ciphers blowfish-cbc, cast128-cbc, all arcfour
variants and the rijndael-cbc aliases for AES.
+ MD5-based and truncated HMAC algorithms.
- OpenSSH 7.2:
Security:
* ssh(1), sshd(8): remove unfinished and unused roaming code
(was already forcibly disabled in OpenSSH 7.1p2).
* ssh(1): eliminate fallback from untrusted X11 forwarding to
trusted forwarding when the X server disables the SECURITY
extension.
* ssh(1), sshd(8): increase the minimum modulus size supported
for diffie-hellman-group-exchange to 2048 bits.
* sshd(8): pre-auth sandboxing is now enabled by default
(previous releases enabled it for new installations via
sshd_config).
New Features:
* all: add support for RSA signatures using SHA-256/512 hash
algorithms based on draft-rsa-dsa-sha2-256-03.txt and
draft-ssh-ext-info-04.txt.
* ssh(1): Add an AddKeysToAgent client option which can be set
to 'yes', 'no', 'ask', or 'confirm', and defaults to 'no'.
When enabled, a private key that is used during
authentication will be added to ssh-agent if it is running
(with confirmation enabled if set to 'confirm').
* sshd(8): add a new authorized_keys option "restrict" that
includes all current and future key restrictions
(no-*-forwarding, etc.). Also add permissive versions of the
existing restrictions, e.g. "no-pty" -> "pty". This
simplifies the task of setting up restricted keys and ensures
they are maximally-restricted, regardless of any permissions
we might implement in the future.
* ssh(1): add ssh_config CertificateFile option to explicitly
list certificates. bz#2436
* ssh-keygen(1): allow ssh-keygen to change the key comment for
all supported formats.
* ssh-keygen(1): allow fingerprinting from standard input, e.g.
"ssh-keygen -lf -"
* ssh-keygen(1): allow fingerprinting multiple public keys in a
file, e.g. "ssh-keygen -lf ~/.ssh/authorized_keys" bz#1319
* sshd(8): support "none" as an argument for sshd_config
Foreground and ChrootDirectory. Useful inside Match blocks to
override a global default. bz#2486
* ssh-keygen(1): support multiple certificates (one per line)
and reading from standard input (using "-f -") for
"ssh-keygen -L"
* ssh-keyscan(1): add "ssh-keyscan -c ..." flag to allow
fetching certificates instead of plain keys.
* ssh(1): better handle anchored FQDNs (e.g. 'cvs.openbsd.org')
in hostname canonicalisation - treat them as already
canonical and remove the trailing '.' before matching
ssh_config.
Bugfixes:
* sftp(1): existing destination directories should not
terminate recursive uploads (regression in openssh 6.8)
* ssh(1), sshd(8): correctly send back SSH2_MSG_UNIMPLEMENTED
replies to unexpected messages during key exchange.
* ssh(1): refuse attempts to set ConnectionAttempts=0, which
does not make sense and would cause ssh to print an
uninitialised stack variable.
* ssh(1): fix errors when attempting to connect to scoped IPv6
addresses with hostname canonicalisation enabled.
* sshd_config(5): list a couple more options usable in Match
blocks.
* sshd(8): fix "PubkeyAcceptedKeyTypes +..." inside a Match
block.
* ssh(1): expand tilde characters in filenames passed to -i
options before checking whether or not the identity file
exists. Avoids confusion for cases where shell doesn't expand
(e.g. "-i ~/file" vs. "-i~/file").
* ssh(1): do not prepend "exec" to the shell command run by
"Match exec" in a config file, which could cause some
commands to fail in certain environments.
* ssh-keyscan(1): fix output for multiple hosts/addrs on one
line when host hashing or a non standard port is in use
* sshd(8): skip "Could not chdir to home directory" message
when ChrootDirectory is active.
* ssh(1): include PubkeyAcceptedKeyTypes in ssh -G config dump.
* sshd(8): avoid changing TunnelForwarding device flags if they
are already what is needed; makes it possible to use tun/tap
networking as non-root user if device permissions and
interface flags are pre-established
* ssh(1), sshd(8): RekeyLimits could be exceeded by one packet.
* ssh(1): fix multiplexing master failure to notice client
exit.
* ssh(1), ssh-agent(1): avoid fatal() for PKCS11 tokens that
present empty key IDs.
* sshd(8): avoid printf of NULL argument.
* ssh(1), sshd(8): allow RekeyLimits larger than 4GB.
* ssh-keygen(1): sshd(8): fix several bugs in (unused) KRL
signature support.
* ssh(1), sshd(8): fix connections with peers that use the key
exchange guess feature of the protocol.
* sshd(8): include remote port number in log messages.
* ssh(1): don't try to load SSHv1 private key when compiled
without SSHv1 support.
* ssh-agent(1), ssh(1): fix incorrect error messages during key
loading and signing errors.
* ssh-keygen(1): don't leave empty temporary files when
performing known_hosts file edits when known_hosts doesn't
exist.
* sshd(8): correct packet format for tcpip-forward replies for
requests that don't allocate a port
* ssh(1), sshd(8): fix possible hang on closed output.
* ssh(1): expand %i in ControlPath to UID.
* ssh(1), sshd(8): fix return type of openssh_RSA_verify.
* ssh(1), sshd(8): fix some option parsing memory leaks.
* ssh(1): add a some debug output before DNS resolution; it's a
place where ssh could previously silently stall in cases of
unresponsive DNS servers.
* ssh(1): remove spurious newline in visual hostkey.
* ssh(1): fix printing (ssh -G ...) of HostKeyAlgorithms=+...
* ssh(1): fix expansion of HostkeyAlgorithms=+...
Documentation:
* ssh_config(5), sshd_config(5): update default algorithm lists
to match current reality.
* ssh(1): mention -Q key-plain and -Q key-cert query options.
* sshd_config(8): more clearly describe what
AuthorizedKeysFile=none does.
* ssh_config(5): better document ExitOnForwardFailure.
* sshd(5): mention internal DH-GEX fallback groups in manual.
* sshd_config(5): better description for MaxSessions option.
Portability:
* sshd(8): fix multiple authentication using S/Key.
- OpenSSH 7.2p2:
Security:
* sshd(8): sanitise X11 authentication credentials to avoid
xauth command injection when X11Forwarding is enabled.

* Fri Apr 11 2014 pcerny@suse.com
- update to 6.6p1
Security:
* sshd(8): when using environment passing with a sshd_config(5)
AcceptEnv pattern with a wildcard. OpenSSH prior to 6.6 could
be tricked into accepting any enviornment variable that
contains the characters before the wildcard character.
Features since 6.5p1:
* ssh(1), sshd(8): removal of the J-PAKE authentication code,
which was experimental, never enabled and has been
unmaintained for some time.
* ssh(1): skip 'exec' clauses other clauses predicates failed
to match while processing Match blocks.
* ssh(1): if hostname canonicalisation is enabled and results
in the destination hostname being changed, then re-parse
ssh_config(5) files using the new destination hostname. This
gives 'Host' and 'Match' directives that use the expanded
hostname a chance to be applied.
Bugfixes:
* ssh(1): avoid spurious "getsockname failed: Bad file
descriptor" in ssh -W. bz#2200, debian#738692
* sshd(8): allow the shutdown(2) syscall in seccomp-bpf and
systrace sandbox modes, as it is reachable if the connection
is terminated during the pre-auth phase.
* ssh(1), sshd(8): fix unsigned overflow that in SSH protocol 1
bignum parsing. Minimum key length checks render this bug
unexploitable to compromise SSH 1 sessions.
* sshd_config(5): clarify behaviour of a keyword that appears
in multiple matching Match blocks. bz#2184
* ssh(1): avoid unnecessary hostname lookups when
canonicalisation is disabled. bz#2205
* sshd(8): avoid sandbox violation crashes in GSSAPI code by
caching the supported list of GSSAPI mechanism OIDs before
entering the sandbox. bz#2107
* ssh(1): fix possible crashes in SOCKS4 parsing caused by
assumption that the SOCKS username is nul-terminated.
* ssh(1): fix regression for UsePrivilegedPort=yes when
BindAddress is not specified.
* ssh(1), sshd(8): fix memory leak in ECDSA signature
verification.
* ssh(1): fix matching of 'Host' directives in ssh_config(5)
files to be case-insensitive again (regression in 6.5).

* Wed Feb 12 2014 pcerny@suse.com
- Update to 6.5p1
Features since 6.4p1:
* ssh(1), sshd(8): support for key exchange using ECDH in
Daniel Bernstein's Curve25519; default when both the client
and server support it.
* ssh(1), sshd(8): support for Ed25519 as a public key type fo
rboth server and client. Ed25519 is an EC signature offering
better security than ECDSA and DSA and good performance.
* Add a new private key format that uses a bcrypt KDF to better
protect keys at rest. Used unconditionally for Ed25519 keys,
on demand for other key types via the -o ssh-keygen(1)
option. Intended to become default in the near future.
Details documented in PROTOCOL.key.
* ssh(1), sshd(8): new transport cipher
"chacha20-poly1305@openssh.com" combining Daniel Bernstein's
ChaCha20 stream cipher and Poly1305 MAC to build an
authenticated encryption mode. Details documented
PROTOCOL.chacha20poly1305.
* ssh(1), sshd(8): refuse RSA keys from old proprietary clients
and servers that use the obsolete RSA+MD5 signature scheme.
It will still be possible to connect with these
clients/servers but only DSA keys will be accepted, and
OpenSSH will refuse connection entirely in a future release.
* ssh(1), sshd(8): refuse old proprietary clients and servers
that use a weaker key exchange hash calculation.
* ssh(1): increase the size of the Diffie-Hellman groups
requested for each symmetric key size. New values from NIST
Special Publication 800-57 with the upper limit specified by
RFC4419.
* ssh(1), ssh-agent(1): support pkcs#11 tokens that only
provide X.509 certs instead of raw public keys (requested as
bz#1908).
* ssh(1): new ssh_config(5) "Match" keyword that allows
conditional configuration to be applied by matching on
hostname, user and result of arbitrary commands.
* ssh(1): support for client-side hostname canonicalisation
using a set of DNS suffixes and rules in ssh_config(5). This
allows unqualified names to be canonicalised to
fully-qualified domain names to eliminate ambiguity when
looking up keys in known_hosts or checking host certificate
names.
* sftp-server(8): ability to whitelist and/or blacklist sftp
protocol requests by name.
* sftp-server(8): sftp "fsync@openssh.com" to support calling
fsync(2) on an open file handle.
* sshd(8): ssh_config(5) PermitTTY to disallow TTY allocation,
mirroring the longstanding no-pty authorized_keys option.
* ssh(1): ssh_config ProxyUseFDPass option that supports the
use of ProxyCommands that establish a connection and then
pass a connected file descriptor back to ssh(1). This allows
the ProxyCommand to exit rather than staying around to
transfer data.
Bugfixes since 6.4p1:
* ssh(1), sshd(8): fix potential stack exhaustion caused by
nested certificates.
* ssh(1): bz#1211: make BindAddress work with
UsePrivilegedPort.
* sftp(1): bz#2137: fix the progress meter for resumed
transfer.
* ssh-add(1): bz#2187: do not request smartcard PIN when
removing keys from ssh-agent.
* sshd(8): bz#2139: fix re-exec fallback when original sshd
binary cannot be executed.
* ssh-keygen(1): make relative-specified certificate expiry
times relative to current time and not the validity start
time.
* sshd(8): bz#2161: fix AuthorizedKeysCommand inside a Match
block.
* sftp(1): bz#2129: symlinking a file would incorrectly
canonicalise the target path.
* ssh-agent(1): bz#2175: fix a use-after-free in the PKCS#11
agent helper executable.
* sshd(8): improve logging of sessions to include the user
name, remote host and port, the session type (shell, command,
etc.) and allocated TTY (if any).
* sshd(8): bz#1297: tell the client (via a debug message) when
their preferred listen address has been overridden by the
server's GatewayPorts setting.
* sshd(8): bz#2162: include report port in bad protocol banner
message.
* sftp(1): bz#2163: fix memory leak in error path in
do_readdir().
* sftp(1): bz#2171: don't leak file descriptor on error.
* sshd(8): include the local address and port in "Connection
from ..." message (only shown at loglevel>=verbose).

* Fri Jan 24 2014 pcerny@suse.com
- Update to 6.4p1
Features since 6.2p2:
* ssh-agent(1) support in sshd(8); allows encrypted hostkeys, or
hostkeys on smartcards.
* ssh(1)/sshd(8): allow optional time-based rekeying via a
second argument to the existing RekeyLimit option. RekeyLimit
is now supported in sshd_config as well as on the client.
* sshd(8): standardise logging of information during user
authentication.
* The presented key/cert and the remote username (if available)
is now logged in the authentication success/failure message on
the same log line as the local username, remote host/port and
protocol in use. Certificates contents and the key
fingerprint of the signing CA are logged too.
* ssh(1) ability to query what cryptographic algorithms are
supported in the binary.
* ssh(1): ProxyCommand=- for cases where stdin and stdout
already point to the proxy.
* ssh(1): allow IdentityFile=none
* ssh(1)/sshd(8): -E option to append debugging logs to a
specified file instead of stderr or syslog.
* sftp(1): support resuming partial downloads with the "reget"
command and on the sftp commandline or on the "get"
commandline with the "-a" (append) option.
* ssh(1): "IgnoreUnknown" configuration option to selectively
suppress errors arising from unknown configuration directives.
* sshd(8): support for submethods to be appended to required
authentication methods listed via AuthenticationMethods.
Bugfixes since 6.2p2:
* sshd(8): fix refusal to accept certificate if a key of a
different type to the CA key appeared in authorized_keys
before the CA key.
* ssh(1)/ssh-agent(1)/sshd(8): Use a monotonic time source for
timers so that things like keepalives and rekeying will work
properly over clock steps.
* sftp(1): update progressmeter when data is acknowledged, not
when it's sent. bz#2108
* ssh(1)/ssh-keygen(1): improve error messages when the current
user does not exist in /etc/passwd; bz#2125
* ssh(1): reset the order in which public keys are tried after
partial authentication success.
* ssh-agent(1): clean up socket files after SIGINT when in debug
mode; bz#2120
* ssh(1) and others: avoid confusing error messages in the case
of broken system resolver configurations; bz#2122
* ssh(1): set TCP nodelay for connections started with -N;
bz#2124
* ssh(1): correct manual for permission requirements on
~/.ssh/config; bz#2078
* ssh(1): fix ControlPersist timeout not triggering in cases
where TCP connections have hung. bz#1917

controlling terminal.
* sftp(1): avoid crashes in libedit when it has been compiled
with multi- byte character support. bz#1990
* sshd(8): when running sshd -D, close stderr unless we have
explicitly requested logging to stderr. bz#1976,
* ssh(1): fix incomplete bzero; bz#2100
* sshd(8): log and error and exit if ChrootDirectory is
specified and running without root privileges.
* Many improvements to the regression test suite. In particular
log files are now saved from ssh and sshd after failures.
* Fix a number of memory leaks. bz#1967 bz#2096 and others
* sshd(8): fix public key authentication when a :style is
appended to the requested username.
* ssh(1): do not fatally exit when attempting to cleanup
multiplexing- created channels that are incompletely opened.
bz#2079
* sshd(8): fix a memory corruption problem triggered during
rekeying when an AES-GCM cipher is selected
* Fix unaligned accesses in umac.c for strict-alignment
architectures. bz#2101
* Fix broken incorrect commandline reporting errors. bz#1448
* Only include SHA256 and ECC-based key exchange methods if
libcrypto has the required support.
* Fix crash in SOCKS5 dynamic forwarding code on
strict-alignment architectures.

instead of hardcoding it
* Tue Nov 13 2012 meissner@suse.com
- Updated to 6.1p1, a bugfix release
Features:
* sshd(8): This release turns on pre-auth sandboxing sshd by default for
new installs, by setting UsePrivilegeSeparation=sandbox in sshd_config.
* ssh-keygen(1): Add options to specify starting line number and number of
lines to process when screening moduli candidates, allowing processing
of different parts of a candidate moduli file in parallel
* sshd(8): The Match directive now supports matching on the local (listen)
address and port upon which the incoming connection was received via
LocalAddress and LocalPort clauses.
* sshd(8): Extend sshd_config Match directive to allow setting AcceptEnv
and {Allow,Deny}{Users,Groups}
* Add support for RFC6594 SSHFP DNS records for ECDSA key types. bz#1978

an argument to refuse all port-forwarding requests.
* sshd(8): Support "none" as an argument for AuthorizedPrincipalsFile
* ssh-keyscan(1): Look for ECDSA keys by default. bz#1971
* sshd(8): Add "VersionAddendum" to sshd_config to allow server operators
to append some arbitrary text to the server SSH protocol banner.
Bugfixes:
* ssh(1)/sshd(8): Don't spin in accept() in situations of file
descriptor exhaustion. Instead back off for a while.
* ssh(1)/sshd(8): Remove hmac-sha2-256-96 and hmac-sha2-512-96 MACs as
they were removed from the specification. bz#2023,
* sshd(8): Handle long comments in config files better. bz#2025

* sshd(8): Allow sshd pre-auth sandboxing to fall-back to the rlimit
sandbox from the Linux SECCOMP filter sandbox when the latter is
not available in the kernel.
* ssh(1): Fix NULL dereference when built with LDNS and using DNSSEC to
retrieve a CNAME SSHFP record.

* Thu May 10 2012 crrodriguez@opensuse.org
- By default openSSH checks at *runtime* if the openssl

are transferred through the local host.
* ssh(1): automatically order the hostkeys requested by the client
based on which hostkeys are already recorded in known_hosts.
* ssh(1)/sshd(8): add a new IPQoS option to specify arbitrary
TOS/DSCP/QoS values instead of hardcoding lowdelay/throughput.
* sftp(1): the sftp client is now significantly faster at performing
directory listings, using OpenBSD glob(3) extensions to preserve
the results of stat(3) operations performed in the course of its
execution rather than performing expensive round trips to fetch
them again afterwards.
* ssh(1): "atomically" create the listening mux socket by binding it on
a temporary name and then linking it into position after listen() has
succeeded.
* ssh(1)/sshd(8): add a KexAlgorithms knob to the client and server
configuration to allow selection of which key exchange methods are
used by ssh(1) and sshd(8) and their order of preference.
* sftp(1)/scp(1): factor out bandwidth limiting code from scp(1) into
a generic bandwidth limiter that can be attached using the atomicio
callback mechanism and use it to add a bandwidth limit option to
sftp(1).
* Support building against openssl-1.0.0a.
* Bug fixes.

* Hostbased authentication may now use certificate host keys.
* ssh-keygen(1) now supports signing certificate using a CA key that
has been stored in a PKCS#11 token.
* ssh(1) will now log the hostname and address that we connected to at
LogLevel=verbose after authentication is successful to mitigate
"phishing" attacks by servers with trusted keys that accept
authentication silently and automatically before presenting fake
password/passphrase prompts.
* Expand %h to the hostname in ssh_config Hostname options.
* Allow ssh-keygen(1) to import (-i) and export (-e) of PEM and PKCS#8
keys in addition to RFC4716 (SSH.COM) encodings via a new -m option
* sshd(8) will now queue debug messages for bad ownership or
permissions on the user's keyfiles encountered during authentication
and will send them after authentication has successfully completed.
* ssh(1) connection multiplexing now supports remote forwarding with
dynamic port allocation and can report the allocated port back to
the user
* sshd(8) now supports indirection in matching of principal names
listed in certificates.
* sshd(8) now has a new AuthorizedPrincipalsFile option to specify a
file containing a list of names that may be accepted in place of the
username when authorizing a certificate trusted via the
sshd_config(5) TrustedCAKeys option.
* Additional sshd_config(5) options are now valid inside Match blocks
* Revised the format of certificate keys.

* Thu Mar 25 2010 meissner@suse.de
- Enable VisualHostKey (ascii art of the hostkey fingerprint) and
HashHostKeys (hardening measure to make them unusable for worms/malicious
users for further host hopping).
* Tue Mar 23 2010 anicka@suse.cz
- update to 5.4p1
* After a transition period of about 10 years, this release disables
SSH protocol 1 by default. Clients and servers that need to use the
legacy protocol must explicitly enable it in ssh_config / sshd_config
or on the command-line.
* Remove the libsectok/OpenSC-based smartcard code and add support for
PKCS#11 tokens. This support is automatically enabled on all
platforms that support dlopen(3) and was inspired by patches written
by Alon Bar-Lev. Details in the ssh(1) and ssh-add(1) manpages.
* Add support for certificate authentication of users and hosts using a
new, minimal OpenSSH certificate format (not X.509). Certificates
contain a public key, identity information and some validity
constraints and are signed with a standard SSH public key using
ssh-keygen(1). CA keys may be marked as trusted in authorized_keys
or via a TrustedUserCAKeys option in sshd_config(5) (for user
authentication), or in known_hosts (for host authentication).
Documentation for certificate support may be found in ssh-keygen(1),
sshd(8) and ssh(1) and a description of the protocol extensions in
PROTOCOL.certkeys.
* Added a 'netcat mode' to ssh(1): "ssh -W host:port ..." This connects
stdio on the client to a single port forward on the server. This
allows, for example, using ssh as a ProxyCommand to route connections
via intermediate servers. bz#1618
* Add the ability to revoke keys in sshd(8) and ssh(1). User keys may
be revoked using a new sshd_config(5) option "RevokedKeys". Host keys
are revoked through known_hosts (details in the sshd(8) man page).
Revoked keys cannot be used for user or host authentication and will
trigger a warning if used.
* Rewrite the ssh(1) multiplexing support to support non-blocking
operation of the mux master, improve the resilience of the master to
malformed messages sent to it by the slave and add support for
requesting port- forwardings via the multiplex protocol. The new
stdio-to-local forward mode ("ssh -W host:port ...") is also
supported. The revised multiplexing protocol is documented in the
file PROTOCOL.mux in the source distribution.
* Add a 'read-only' mode to sftp-server(8) that disables open in write
mode and all other fs-modifying protocol methods. bz#430
* Allow setting an explicit umask on the sftp-server(8) commandline to
override whatever default the user has. bz#1229
* Many improvements to the sftp(1) client, many of which were
implemented by Carlos Silva through the Google Summer of Code
program:
- Support the "-h" (human-readable units) flag for ls
- Implement tab-completion of commands, local and remote filenames
- Support most of scp(1)'s commandline arguments in sftp(1), as a
first step towards making sftp(1) a drop-in replacement for scp(1).
Note that the rarely-used "-P sftp_server_path" option has been
moved to "-D sftp_server_path" to make way for "-P port" to match
scp(1).
- Add recursive transfer support for get/put and on the commandline
* New RSA keys will be generated with a public exponent of RSA_F4 ==
(2**16)+1 == 65537 instead of the previous value 35.
* Passphrase-protected SSH protocol 2 private keys are now protected
with AES-128 instead of 3DES. This applied to newly-generated keys
as well as keys that are reencrypted (e.g. by changing their
passphrase).
- cleanup in patches
* Tue Mar 02 2010 coolo@novell.com
- do not use paths at all, but prereq packages
* Sat Feb 27 2010 aj@suse.de

are still running (e.e. being logged in from remote)
* Fri Jun 19 2009 coolo@novell.com
- disable as-needed for this package as it fails to build with it
* Tue May 26 2009 anicka@suse.cz
- disable -f in startproc to calm the warning (bnc#506831)
* Thu Apr 23 2009 lnussel@suse.de
- do not enable sshd by default
* Mon Feb 23 2009 anicka@suse.cz
- update to 5.2p1
* This release changes the default cipher order to prefer the AES CTR
modes and the revised "arcfour256" mode to CBC mode ciphers that are
susceptible to CPNI-957037 "Plaintext Recovery Attack Against SSH".
* This release also adds countermeasures to mitigate CPNI-957037-style
attacks against the SSH protocol's use of CBC-mode ciphers. Upon
detection of an invalid packet length or Message Authentication
Code, ssh/sshd will continue reading up to the maximum supported
packet length rather than immediately terminating the connection.
This eliminates most of the known differences in behaviour that
leaked information about the plaintext of injected data which formed
the basis of this attack. We believe that these attacks are rendered
infeasible by these changes.
* Added a -y option to ssh(1) to force logging to syslog rather than
stderr, which is useful when running daemonised (ssh -f)
* The sshd_config(5) ForceCommand directive now accepts commandline
arguments for the internal-sftp server.
* The ssh(1) ~C escape commandline now support runtime creation of
dynamic (-D) port forwards.
* Support the SOCKS4A protocol in ssh(1) dynamic (-D) forwards.
(bz#1482)
* Support remote port forwarding with a listen port of '0'. This
informs the server that it should dynamically allocate a listen
port and report it back to the client. (bz#1003)
* sshd(8) now supports setting PermitEmptyPasswords and
AllowAgentForwarding in Match blocks
* Repair a ssh(1) crash introduced in openssh-5.1 when the client is
sent a zero-length banner (bz#1496)
* Due to interoperability problems with certain
broken SSH implementations, the eow@openssh.com and
no-more-sessions@openssh.com protocol extensions are now only sent
to peers that identify themselves as OpenSSH.
* Make ssh(1) send the correct channel number for
SSH2_MSG_CHANNEL_SUCCESS and SSH2_MSG_CHANNEL_FAILURE messages to
avoid triggering 'Non-public channel' error messages on sshd(8) in
openssh-5.1.
* Avoid printing 'Non-public channel' warnings in sshd(8), since the
ssh(1) has sent incorrect channel numbers since ~2004 (this reverts
a behaviour introduced in openssh-5.1).
* Avoid double-free in ssh(1) ~C escape -L handler (bz#1539)
* Correct fail-on-error behaviour in sftp(1) batchmode for remote
stat operations. (bz#1541)
* Disable nonfunctional ssh(1) ~C escape handler in multiplex slave
connections. (bz#1543)
* Avoid hang in ssh(1) when attempting to connect to a server that
has MaxSessions=0 set.
* Multiple fixes to sshd(8) configuration test (-T) mode
* Several core and portable OpenSSH bugs fixed: 1380, 1412, 1418,
1419, 1421, 1490, 1491, 1492, 1514, 1515, 1518, 1520, 1538, 1540
* Many manual page improvements.

* Sun Aug 24 2008 coolo@suse.de
- fix fillup macro usage
* Fri Aug 22 2008 prusnak@suse.cz
- enabled SELinux support [Fate#303662]
* Tue Jul 22 2008 anicka@suse.cz
- update to 5.1p1
* sshd(8): Avoid X11 man-in-the-middle attack on HP/UX (and possibly
other platforms) when X11UseLocalhost=no
* Introduce experimental SSH Fingerprint ASCII Visualisation to ssh(1)
and ssh-keygen(1). Visual fingerprinnt display is controlled by a new
ssh_config(5) option "VisualHostKey".
* sshd_config(5) now supports CIDR address/masklen matching in "Match
address" blocks, with a fallback to classic wildcard matching.
* sshd(8) now supports CIDR matching in ~/.ssh/authorized_keys
from="..." restrictions, also with a fallback to classic wildcard
matching.
* Added an extended test mode (-T) to sshd(8) to request that it write
its effective configuration to stdout and exit. Extended test mode
also supports the specification of connection parameters (username,
source address and hostname) to test the application of
sshd_config(5) Match rules.
* ssh(1) now prints the number of bytes transferred and the overall
connection throughput for SSH protocol 2 sessions when in verbose
mode (previously these statistics were displayed for protocol 1
connections only).
* sftp-server(8) now supports extension methods statvfs@openssh.com and
fstatvfs@openssh.com that implement statvfs(2)-like operations.
* sftp(1) now has a "df" command to the sftp client that uses the
statvfs@openssh.com to produce a df(1)-like display of filesystem
space and inode utilisation (requires statvfs@openssh.com support on
the server)
* Added a MaxSessions option to sshd_config(5) to allow control of the
number of multiplexed sessions supported over a single TCP connection.
This allows increasing the number of allowed sessions above the
previous default of 10, disabling connection multiplexing
(MaxSessions=1) or disallowing login/shell/subsystem sessions
entirely (MaxSessions=0).
* Added a no-more-sessions@openssh.com global request extension that is
sent from ssh(1) to sshd(8) when the client knows that it will never
request another session (i.e. when session multiplexing is disabled).
This allows a server to disallow further session requests and
terminate the session in cases where the client has been hijacked.
* ssh-keygen(1) now supports the use of the -l option in combination
with -F to search for a host in ~/.ssh/known_hosts and display its
fingerprint.
* ssh-keyscan(1) now defaults to "rsa" (protocol 2) keys, instead of
"rsa1".
* Added an AllowAgentForwarding option to sshd_config(8) to control
whether authentication agent forwarding is permitted. Note that this
is a loose control, as a client may install their own unofficial
forwarder.
* ssh(1) and sshd(8): avoid unnecessary malloc/copy/free when receiving
network data, resulting in a ~10% speedup
* ssh(1) and sshd(8) will now try additional addresses when connecting
to a port forward destination whose DNS name resolves to more than
one address. The previous behaviour was to try the only first address
and give up if that failed. (bz#383)
* ssh(1) and sshd(8) now support signalling that channels are
half-closed for writing, through a channel protocol extension
notification "eow@openssh.com". This allows propagation of closed
file descriptors, so that commands such as:
"ssh -2 localhost od /bin/ls | true"
do not send unnecessary data over the wire. (bz#85)
* sshd(8): increased the default size of ssh protocol 1 ephemeral keys
from 768 to 1024 bits.
* When ssh(1) has been requested to fork after authentication
("ssh -f") with ExitOnForwardFailure enabled, delay the fork until
after replies for any -R forwards have been seen. Allows for robust
detection of -R forward failure when using -f. (bz#92)
* "Match group" blocks in sshd_config(5) now support negation of
groups. E.g. "Match group staff,!guests" (bz#1315)
* sftp(1) and sftp-server(8) now allow chmod-like operations to set
set[ug]id/sticky bits. (bz#1310)
* The MaxAuthTries option is now permitted in sshd_config(5) match
blocks.
* Multiplexed ssh(1) sessions now support a subset of the ~ escapes
that are available to a primary connection. (bz#1331)
* ssh(1) connection multiplexing will now fall back to creating a new
connection in most error cases. (bz#1439 bz#1329)
* Added some basic interoperability tests against Twisted Conch.
* Documented OpenSSH's extensions to and deviations from the published
SSH protocols (the PROTOCOL file in the distribution)
* Documented OpenSSH's ssh-agent protocol (PROTOCOL.agent).
* bugfixes

* Wed Apr 02 2008 anicka@suse.cz
- update to 4.9p1
* Disable execution of ~/.ssh/rc for sessions where a command has been
forced by the sshd_config ForceCommand directive. Users who had
write access to this file could use it to execute abritrary commands.
This behaviour was documented, but was an unsafe default and an extra
hassle for administrators.
* Added chroot(2) support for sshd(8), controlled by a new option
"ChrootDirectory". Please refer to sshd_config(5) for details, and
please use this feature carefully. (bz#177 bz#1352)
* Linked sftp-server(8) into sshd(8). The internal sftp server is
used when the command "internal-sftp" is specified in a Subsystem
or ForceCommand declaration. When used with ChrootDirectory, the
internal sftp server requires no special configuration of files
inside the chroot environment. Please refer to sshd_config(5) for
more information.
* Added a "no-user-rc" option for authorized_keys to disable execution
of ~/.ssh/rc
* Added a protocol extension method "posix-rename@openssh.com" for
sftp-server(8) to perform POSIX atomic rename() operations.
(bz#1400)
* Removed the fixed limit of 100 file handles in sftp-server(8). The
server will now dynamically allocate handles up to the number of
available file descriptors. (bz#1397)
* ssh(8) will now skip generation of SSH protocol 1 ephemeral server
keys when in inetd mode and protocol 2 connections are negotiated.
This speeds up protocol 2 connections to inetd-mode servers that
also allow Protocol 1 (bz#440)
* Accept the PermitRootLogin directive in a sshd_config(5) Match
block. Allows for, e.g. permitting root only from the local
network.
* Reworked sftp(1) argument splitting and escaping to be more
internally consistent (i.e. between sftp commands) and more
consistent with sh(1). Please note that this will change the
interpretation of some quoted strings, especially those with
embedded backslash escape sequences. (bz#778)
* Support "Banner=none" in sshd_config(5) to disable sending of a
pre-login banner (e.g. in a Match block).
* ssh(1) ProxyCommands are now executed with $SHELL rather than
/bin/sh.
* ssh(1)'s ConnectTimeout option is now applied to both the TCP
connection and the SSH banner exchange (previously it just covered
the TCP connection). This allows callers of ssh(1) to better detect
and deal with stuck servers that accept a TCP connection but don't
progress the protocol, and also makes ConnectTimeout useful for
connections via a ProxyCommand.
* Many new regression tests, including interop tests against PuTTY's
plink.
* Support BSM auditing on Mac OS X

verified for source tarball. Bugs fixed with this version:
[#31637] (CAN-2003-0786, CAN-2003-0786). Briefly:
1) SSH1 PAM challenge response auth ignored the result of the
authentication (with privsep off)
2) The PAM conversation function trashed the stack, by referring
to the **resp parameter as an array of pointers rather than
as a pointer to an array of struct pam_responses.
At least security bug 1) is exploitable.
