- update to 1.14.4 (bsc#1204111, CVE-2022-42010,
bsc#1204112, CVE-2022-42011,
bsc#1204113, CVE-2022-42012):
This is a security update for the dbus 1.14.x stable branch, fixing
denial-of-service issues (CVE-2022-42010, -42011, -42012) and applying
security hardening (dbus#416).
Behaviour changes:
* On Linux, dbus-daemon and other uses of DBusServer now create a
path-based Unix socket, unix:path=..., when asked to listen on a
unix:tmpdir=... address. This makes unix:tmpdir=... equivalent to
unix:dir=... on all platforms.
Previous versions would have created an abstract socket, unix:abstract=...,
in this situation.
This change primarily affects the well-known session bus when run via
dbus-launch(1) or dbus-run-session(1). The user bus, enabled by configuring
dbus with --enable-user-session and running it on a systemd system,
already used path-based Unix sockets and is unaffected by this change.
This behaviour change prevents a sandbox escape via the session bus socket
in sandboxing frameworks that can share the network namespace with the host
system, such as Flatpak.
This change might cause a regression in situations where the abstract socket
is intentionally shared between the host system and a chroot or container,
such as some use-cases of schroot(1). That regression can be resolved by
using a bind-mount to share either the D-Bus socket, or the whole /tmp
directory, with the chroot or container.
(dbus#416, Simon McVittie)
* Denial of service fixes:
- Evgeny Vereshchagin discovered several ways in which an authenticated
local attacker could cause a crash (denial of service) in
dbus-daemon --system or a custom DBusServer. In uncommon configurations
these could potentially be carried out by an authenticated remote attacker.
- An invalid array of fixed-length elements where the length of the array
is not a multiple of the length of the element would cause an assertion
failure in debug builds or an out-of-bounds read in production builds.
This was a regression in version 1.3.0.
(dbus#413, CVE-2022-42011; Simon McVittie)
- A syntactically invalid type signature with incorrectly nested parentheses
and curly brackets would cause an assertion failure in debug builds.
Similar messages could potentially result in a crash or incorrect message
processing in a production build, although we are not aware of a practical
example. (dbus#418, CVE-2022-42010; Simon McVittie)
- A message in non-native endianness with out-of-band Unix file descriptors
would cause a use-after-free and possible memory corruption in production
builds, or an assertion failure in debug builds. This was a regression in
version 1.3.0. (dbus#417, CVE-2022-42012; Simon McVittie)
- Preserve errno on failure to open /proc/self/oom_score_adj
(dbus!285, Gentoo#834725; Mike Gilbert)
- On Linux, don't log warnings if oom_score_adj is read-only but does not
need to be changed (dbus!291, Simon McVittie)
- Slightly improve error-handling for inotify
(dbus!235, Simon McVittie)
- Don't crash if dbus-daemon is asked to watch more than 128 directories
for changes (dbus!302, Jan Tojnar)

- Update to version 1.14.0:
+ Dependencies:
- dbus now requires at least a basic level of support for C99
variadic macros, as implemented in gcc >= 3, all versions of
Clang, and MSVC >= 2005. In practice this requirement has
existed since version 1.9.2, but it is now official.
- dbus now requires a C99-compatible va_copy() macro
(or a __va_copy() macro with the same behaviour), except when
building for Windows using MSVC and CMake.
- On Unix platforms, if getpwnam_r() and getgrnam_r() are
implemented, they must be POSIX-conformant. The non-POSIX
signature seen in ancient Solaris versions will no longer
work.
- GLib >= 2.38 is required if full test coverage is enabled
(reduced from 2.40 in dbus 1.12.x.)
- Building using CMake now requires CMake 3.4.
- Building documentation using CMake now requires xsltproc,
Docbook DTDs (for example docbook-xml on Debian derivatives),
and Docbook XSLT stylesheets (for example docbook-xsl on
Debian derivatives). Using KDE's meinproc4 documentation
processor is no longer supported.
+ Build-time configuration changes: Move CMake build system to
top level, matching normal practice for CMake projects
+ Deprecations:
- Third-party software should install default dbus policies for
the system bus into ${datadir}/dbus-1/system.d (this has been
supported since dbus 1.10, released in August 2015).
Installing default dbus policies in
${sysconfdir}/dbus-1/system.d is now considered to be
deprecated. Policy files in ${sysconfdir}/dbus-1/system.d
continue to be read, but this directory should only be used
by system administrators wishing to override the default
policies.
- The ${datadir} applicable to dbus is usually /usr/share and
the ${sysconfdir} is usually /etc.
- A similar pattern applies to the session bus policies in
session.d.
- The dbus-send(1) man page now documents --bus and --peer
instead of the old --address synonym for --peer, which has
been deprecated since the introduction of --bus and --peer in
1.7.6
- The dbus-daemon man page now has scarier warnings about
<allow_anonymous/> and non-local TCP, which are insecure and
should not be used, particularly for the standard system and
session buses.
- DBusServer (and hence the dbus-daemon) no longer accepts
usernames (login names) for the recommended EXTERNAL
authentication mechanism, only numeric user IDs or the empty
string. See 1.13.0 release notes for full details.
+ New features:
- On Linux 4.13 or later when built against a suitable glibc
version, GetConnectionCredentials() now includes
UnixGroupIDs, the effective group IDs of the initiator of the
connection, taken from SO_PEERGROUPS.
- On Linux 4.13 or later, <policy group="…"> now uses the
SO_PEERGROUPS credentials-passing socket option to get the
effective group IDs of the initiator of the connection. See
1.13.4 release notes for details.
- Add a --sender option to dbus-send, which requests a name and
holds it until the signal has been sent
- dbus-daemon <allow> and <deny> rules can now specify a
send_destination_prefix attribute, which is like a
combination of send_destination and the arg0namespace keyword
in match rules. See 1.13.12 release notes for more details.
- The dbus-daemon now filters the messages that it relays,
removing header fields that it does not understand. Clients
must not rely on this behaviour unless they have confirmed
that they are connected to a suitable message bus
implementation, for example by querying its Features
property.
- The dbus-daemon now emits a signal,
ActivatableServicesChanged, when the list of activatable
services may have changed. Support for this signal can be
discovered by querying the Features property.
- It is now possible to disable traditional (non-systemd)
service activation at build-time (Autotools:
- -disable-traditional-activation, CMake:
- DENABLE_TRADITIONAL_ACTIVATION=OFF). See 1.13.10 release
notes for details.
- The API reference manual can be built as a Qt compiled help
file if qhelpgenerator(-qt5) is available. See 1.13.16
release notes for details.
+ Miscellaneous behaviour changes:
- When using the "user bus" (--enable-user-session), put the
dbus-daemon in the session slice
- Several environment variables set by systemd are no longer
passed on to activated services
- If the dbus-daemon is compiled for Linux with systemd
support, it now informs systemd that it is ready for use via
the sd_notify() mechanism.
- Tarball releases no longer contain pre-2007 changelogs and
are now compressed with xz, making them around 35% smaller.
- Drop conditionals for old obsolete versions of openSUSE.
- Rebase patches with quilt.
- Use https for source and sig URL.
* Tue Mar 01 2022 Bjørn Lie <bjorn.lie@gmail.com>
- Update to version 1.12.22:
+ On Linux, when using traditional (non-systemd) service
activation, don't log warnings about failing to reset OOM score
adjustment if the process is already more susceptible to the
OOM killer, as user processes usually are with systemd ≥ 250.
+ On Linux, when using traditional (non-systemd) system bus
activation, reset the OOM score adjustment to 0 as intended.
If the system dbus-daemon is protected from the OOM killer,
this avoids that protection unintentionally being inherited by
every system service.
+ Avoid malloc() after fork on non-GNU libc.
+ Fix build with clang 13 by using Standard C offsetof where
available.
+ Fix build of tests on FreeBSD.
+ Make documentation build more reproducible.
+ On Unix, make X11 autolaunch cope with slashes in DISPLAY.
+ Don't try to raise RLIMIT_NOFILE beyond OPEN_MAX on macOS.
+ Fix compilation if embedded tests are enabled but verbose mode
and stats are both disabled.
+ On Linux, fix a race condition in the integration test for
transient services.

- Use libalternatives instead of update-alternatives.
* Thu Jul 16 2020 Matthias Eliasson <elimat@opensuse.org>
- Update to 1.12.20
* On Unix, avoid a use-after-free if two usernames have the same
numeric uid. In older versions this could lead to a crash (denial of
service) or other undefined behaviour, possibly including incorrect
authorization decisions if <policy group=...> is used.
Like Unix filesystems, D-Bus' model of identity cannot distinguish
between users of different names with the same numeric uid, so this
configuration is not advisable on systems where D-Bus will be used.
Thanks to Daniel Onaca.
(dbus#305, dbus!166; Simon McVittie)
- From 1.12.18
* CVE-2020-12049: If a message contains more file descriptors than can
be sent, close those that did get through before reporting error.
Previously, a local attacker could cause the system dbus-daemon (or
another system service with its own DBusServer) to run out of file
descriptors, by repeatedly connecting to the server and sending fds that
would get leaked.
Thanks to Kevin Backhouse of GitHub Security Lab.
(dbus#294, GHSL-2020-057; Simon McVittie)
* Fix a crash when the dbus-daemon is terminated while one or more
monitors are active (dbus#291, dbus!140; Simon McVittie)
* The dbus-send(1) man page now documents --bus and --peer instead of
the old --address synonym for --peer, which has been deprecated since
the introduction of --bus and --peer in 1.7.6
(fd.o #48816, dbus!115; Chris Morin)
* Fix a wrong environment variable name in dbus-daemon(1)
(dbus#275, dbus!122; Mubin, Philip Withnall)
* Fix formatting of dbus_message_append_args example
(dbus!126, Felipe Franciosi)
* Avoid a test failure on Linux when built in a container as uid 0, but
without the necessary privileges to increase resource limits
(dbus!58, Debian #908092; Simon McVittie)
* When building with CMake, cope with libX11 in a non-standard location
(dbus!129, Tuomo Rinne)
