| Summary: SQLite support for Dovecot | |
Dovecot is an IMAP and POP3 server for Linux and UNIX-like systems, written primarily with security in mind. Although it is written in C, it uses several coding techniques to avoid most of the common pitfalls. Dovecot can work with standard mbox and maildir formats and is fully compatible with UW-IMAP and Courier IMAP servers as well as mail clients accessing the mailboxes directly. This package holds the files needed for SQLite support.

- update to 2.3.21.1 and pigeonhole 0.5.21.1
Dovecot 2.3.21.1
- CVE-2024-23184: A large number of address headers in email resulted
in excessive CPU usage. [boo#1229184]
- CVE-2024-23185: Abnormally large email headers are now truncated or
discarded, with a limit of 10MB on a single header and 50MB for all
the headers of all the parts of an email. [boo#1229183]
- oauth2: Dovecot would send client_id and client_secret as POST parameters
to introspection server. These need to be optionally in Basic auth
instead as required by OIDC specification.
- oauth2: JWT key type check was too strict.
- oauth2: JWT token audience was not validated against client_id as
required by OIDC specification.
- oauth2: XOAUTH2 and OAUTHBEARER mechanisms were not giving out
protocol specific error message on all errors. This broke OIDC discovery.
- oauth2: JWT aud validation was not performed if aud was missing
from token, but was configured on Dovecot.
* Mon Nov 06 2023 Dominique Leuenberger <dimstar@opensuse.org>
- Fix build with RPM 4.19: unnumbered patches are no longer
supported.
* Fri Sep 15 2023 Arjen de Korte <suse+build@de-korte.org>
- update to 2.3.21 and pigeonhole 0.5.21
Dovecot 2.3.21
* lib-oauth2: Allow JWT tokens to be validated with missing typ field.
The typ field is left out by some key issuers to conserve space,
notably kubernetes. Now missing typ is tolerated, but if present, it
still must be "jwt".
+ auth: Auth passdb and userdb reply can contain "event_<name>=value"
which will be added to login event and mail user event respectively.
+ lib-master: Set process title during various initialization stages to
clearly describe what the process is waiting on.
+ lib-storage: The mail_temp_scan_interval is now fuzzed incrementing it
by 0..30% based on username's hash to reduce the chance of load spikes.
+ lib-storage: The temp file scan has been moved from the open of the
mailbox to the close, to reduce the latency perceived by users.
+ stats: If metric has fields specified, all these fields are
exported as counters to prometheus exposition.
See https://doc.dovecot.org/configuration_manual/stats/openmetrics/.
- *-login: Processes might have crashed when a SSL connection disconnects
uncleanly.
- acl: When plugin was loaded \HasChildren and \HasNoChildren flags
were calculated incorrectly for mailboxes containing '*' and '%'
in their names.
- auth: Crash occured if a connection to PostgreSQL database server
failed during startup.
- auth: Logins with invalid passwords (e.g. unknown scheme) in passdb
were failing with "password mismatch" instead of "internal error".
- auth: XOAUTH2 and OAUTHBEARER mechanisms were not giving out protocol
specific error message on all errors. This especially broke OIDC
discovery.
- dbox: When last_temp_file_scan header wasn't set (especially after
dsync migration), the next mailbox open always triggers the temp file
scan. This could have caused a load spike after migrations. Fixed by
using the mailbox directory's atime when the header isn't set, which
usually moves the scan time into the future.
- dict-redis: A crash would occur on transaction rollback.
- dsync: Infinite loop causing out of memory would occur when handling
mailbox deletion from remote end and hierarchy separators would differ.
- dsync: Incremental dsync failed for folder names ending with '%',
unless BROKENCHAR was set. Also folder names with '%' elsewhere in
them caused each incremental dsync to unnecessarily rename the folder
to a temporary name and back. v2.3.19 regression.
- imap-hibernate: If an IMAP client unhibernation timed out with
"(version received)", the unhibernation could still have successfully
finished later on and continued working normally. This was rather
confusing, because imap-hibernate already logged that the client got
disconnected. Avoid this by forcing the connection to shutdown on
unhibernation timeout.
- imapc: Crashed when a folder mapped through the virtual plugin
disappears from the storage.
- imapc: EXPUNGE, EXISTS or FETCH replies from a server for a previously
selected mailbox could have been processed as if they belonged to the
new mailbox currently being selected. This could have caused warnings.
- lib-http: Dovecot HTTP server (doveadm, stats/openmetrics) may have
disconnected HTTP clients before the response is fully sent. This
happened only on busy servers where kernel's socket buffers were
rather full.
- lib-http: Fixed a potential crash on http-server if a client
disconnected early. v2.3.18 regression.
- lib-index: Index file corruption could have caused a crash. Fixes:
Panic: file mail-transaction-log-view.c: line 165 (mail_transaction_log_view_set):
assertion failed: (min_file_seq <= max_file_seq).
- lib-index: Purging an existing >1GB cache file can crash. Now cache
files still above 1GB after purging are removed. Fixes:
Panic: file mail-index-util.c: line 10 (mail_index_uint32_to_offset):
assertion failed: (offset < 0x40000000)
- lib-lua: A HTTP client could not resolve DNS names in mail processes,
because it expected "the dns-client" socket to exist in the current
directory.
- lib-oauth2: Dovecot would send client_id and client_secret as POST
parameters to the introspection server. These need to be optionally in
Basic auth instead.
- lib-oauth2: JWT aud validation was not performed if aud was missing
from a token, but was configured on Dovecot.
- lib-oauth2: JWT key type check was too strict.
- lib-oauth2: JWT token audience was not validated against client_id as
required by the specification.
- lib-ssl-iostream: Using the ssl_require_crl=yes setting may have caused
CRL check failures for outgoing SSL/TLS connections, although it was
supposed to affect checking CRLs only for client-side SSL
certificates. v2.3.17 regression.
- lib-sql: MySQL driver leaked memory when connection failed.
- lib-storage: Various fixes when running into out of disk space.
- master: Service idle_kill setting didn't work properly on busy
servers. It was very unlikely that any process was idling long enough
to become killed. Also the idle_kill handling code was using quite a
lot of CPU on the master process when there were a lot of processes
(e.g. imap). The new behavior is to track the lowest number of idling
processes every idle_kill time interval and then kill that many idling
processes.
- mdbox: Temp file scan was done for always empty directories.
- mdbox: The fdatasync() call was done in wrong parent directory when
writing mails. Also on a failure it crashed instead of logging an error.
- notify_status: The plugin crashes if any user initialization fails.
- pop3: Sending command with the ':' character caused an assert-crash.
v2.3.18 regression. Fixes: Panic: event_reason_code_prefix(): name has ':'
- stats: Fix panic when a nonexistent event exporter was referenced while
adding a new metric dynamically via doveadm stats add. This produces
a proper error now.
- stats: If process exported a lot of events and then exited, some of
the last events may have become lost.
- stats: Invalid Prometheus label names were created with specific
histogram group_by configurations. Prometheus rejected these labels.
- welcome: The plugin didn't execute in some situations that created
INBOX but didn't open it, e.g. if GETMETADATA was used before the
INBOX was opened.
Pigeonhole v0.5.21
- sieve: Using the deleteheader action on a message with a broken/invalid
header can cause the Sieve interpreter to crash with an assert panic.
This can happen e.g. when the message is missing the empty EOH line
between the headers and the body of the message. Fixes:
Panic: file edit-mail.c: line 820 (edit_mail_headers_parse):
assertion failed: (body_offset > 0).
- sieve: Pigeonhole added an extra Message-ID header during mail
forwarding when the existing one was invalid. Now it adds the
Message-ID only if it is entirely missing. Existing Message-ID(s) are
left unchanged.
* Mon Mar 27 2023 Martin Liška <mliska@suse.cz>
- Add upstream fix-strict-aliasing.patch that addresses violation
of strict aliasing.
* Thu Mar 23 2023 Martin Liška <mliska@suse.cz>
- Enable LTO now as it works now (boo#1156301).
* Sun Feb 05 2023 Arjen de Korte <suse+build@de-korte.org>
- Add patch to fix building with OpenSSL-3 (boo#1207958)
+ fix-build-with-openssl-3.patch
* Thu Dec 22 2022 Michael Ströder <michael@stroeder.com>
- removed obsolete dovecot-2.3.19-fix-doveadm-sync-special-folders.patch
- update to 2.3.20 and pigeonhole 0.5.20
+ Add dsync_features=no-header-hashes. When this setting is enabled and
one dsync side doesn't support mail GUIDs (i.e. imapc), there is no
fallback to using header hashes. Instead, dsync assumes that all mails
with identical IMAP UIDs contains the same mail contents. This can
significantly improve dsync performance with some IMAP servers that
don't support caching Date/Message-ID headers.
+ lua: HTTP client has more settings now, see
https://doc.dovecot.org/admin_manual/lua/#dovecot.http.client
+ replicator: "doveadm replicator status" command now outputs when the
next sync is expected for the user.
- LAYOUT=index: duplicate GUIDs were not cleaned out. Also the list
recovery was not optimal.
- auth: Assert crash would occur when iterating multiple userdb
backends.
- director: Logging into director using master user with
auth_master_user_separator character redirected user to a wrong
backend, unless master_user_separator setting was also set to the same
value. Merged these into auth_master_user_separator.
- dsync: Couldn't always fix folder GUID conflicts automatically with
Maildir format. This resulted in replication repeatedly failing
with "Remote lost mailbox GUID".
- dsync: Failed to migrate INBOX when using namespace prefix=INBOX/,
resulting in "Remote lost mailbox GUID" errors.
- dsync: INBOX was created too early with namespace prefix=INBOX/,
resulting a GUID conflict. This may have been resolved automatically,
but not always.
- dsync: v2.3.18 regression: Wrong imapc password with dsync caused
Panic: file lib-event.c: line 506 (event_pop_global):
assertion failed: (event == current_global_event)
- imapc: Requesting STATUS for a mailbox with imapc and INDEXPVT
configured did not return correct (private) unseen counts.
- lib-dict: Process would crash when committing data to redis without
dict proxy.
- lib-mail: Corrupted cached BODYSTRUCTURE caused panic during FETCH.
Fixes: Panic: file message-part-data.c: line 579 (message_part_is_attachment):
assertion failed: (data != NULL). v2.3.13 regression.
- lib-storage: mail_attribute_dict with dict-sql failed when it tried to
lookup empty dict keys.
- lib: ioloop-kqueue was missing include breaking some BSD builds.
- lua-http: Dovecot Lua HTTP client could not resolve DNS names in mail
processes, because it expected "dns-client" socket to exist in the
current directory.
- oauth2: Using %{oauth2:name} variables could cause useless
introspections.
- pop3: Sending POP3 command with ':' character caused an assert-crash.
v2.3.18 regression.
- replicator: Replication queue had various issues, potentially causing
replication requests to become stuck.
- stats: Invalid Prometheus label names were created with specific
histogram group_by configurations. Prometheus rejected these labels.
* Tue Dec 20 2022 Thiago Macieira <thiago@kde.org>
- Add suppor for Zstandard (zstd) to the compression (zlib) plugin: zstd has a
better compression ratio than gzip for the same amount of CPU work, or takes
less CPU to compress the same. It's also faster to decompress.
- Add dovecot-2.3.19-fix-doveadm-sync-special-folders.patch:
Patches from the release-2.3 branch that fix issues importing the INBOX
folder from a Cyrus IMAP server and dealing with auto-creating folders that
haven't yet been created
* Tue Jun 14 2022 Michael Ströder <michael@stroeder.com>
- update to 2.3.19.1
* doveadm deduplicate: Non-duplicate mails were deleted. v2.3.19 regression.
* auth: Crash would occur when iterating multiple backends.
Fixes: Panic: file userdb-blocking.c: line 125 (userdb_blocking_iter_next): assertion failed: (ctx->conn != NULL)
* Tue May 10 2022 Arjen de Korte <suse+build@de-korte.org>
- update to 2.3.19 and pigeonhole 0.5.19
Dovecot 2.3.19
+ Added mail_user_session_finished event, which is emitted when the mail
user session is finished (e.g. imap, pop3, lmtp). It also includes
fields with some process statistics information.
See https://doc.dovecot.org/admin_manual/list_of_events/ for more
information.
+ Added process_shutdown_filter setting. When an event matches the filter,
the process will be shutdown after the current connection(s) have
finished. This is intended to reduce memory usage of long-running imap
processes that keep a lot of memory allocated instead of freeing it to
the OS.
+ auth: Add cache hit indicator to auth passdb/userdb finished events.
See https://doc.dovecot.org/admin_manual/list_of_events/ for more
information.
+ doveadm deduplicate: Performance is improved significantly.
+ imapc: COPY commands were sent one mail at a time to the remote IMAP
server. Now the copying is buffered, so multiple mails can be copied
with a single COPY command.
+ lib-lua: Add a Lua interface to Dovecot's HTTP client library. See
https://doc.dovecot.org/admin_manual/lua/ for more information.
- auth: Cache lookup would use incorrect cache key after username change.
- auth: Improve handling unexpected LDAP connection errors/hangs.
Try to fix up these cases by reconnecting to the LDAP server and
aborting LDAP requests earlier.
- auth: Process crashed if userdb iteration was attempted while auth-workers
were already full handling auth requests.
- auth: db-oauth2: Using %{oauth2:name} variables caused unnecessary
introspection requests.
- dict: Timeouts may have been leaked at deinit.
- director: Ring may have become unstable if a backend's tag was changed.
It could also have caused director process to crash.
- doveadm kick: Numeric parameter was treated as IP address.
- doveadm: Proxying can panic when flushing print output. Fixes
Panic: file ioloop.c: line 865 (io_loop_destroy): assertion failed:
(ioloop == current_ioloop).
- doveadm sync: BROKENCHAR was wrongly changed to '_' character when
migrating mailboxes. This was set by default to %, so any mailbox
names containing % characters were modified to "_25".
- imapc: Copying or moving mails with doveadm to an imapc mailbox could
have produced "Error: Syncing mailbox '[...]' failed" Errors. The
operation itself succeeded but attempting to sync the destination
mailbox failed.
- imapc: Prevent index log synchronization errors when two or more imapc
sessions are adding messages to the same mailbox index files, i.e.
INDEX=MEMORY is not used.
- indexer: Process was slowly leaking memory for each indexing request.
- lib-fts: fts header filters caused binary content to be sent to the
indexer with non-default configuration.
- doveadm-server: Process could hang in some situations when printing
output to TCP client, e.g. when printing doveadm sync state.
- lib-index: dovecot.index.log files were often read and parsed entirely,
rather than only the parts that were actually necessary. This mainly
increased CPU usage.
- lmtp-proxy: Session ID forwarding would cause same session IDs being
used when delivering same mail to multiple backends.
- log: Log prefix update may have been lost if log process was busy.
This could have caused log prefixes to be empty or in some cases
reused between sessions, i.e. log lines could have been logged for the
wrong user/session.
- mail_crypt: Plugin crashes if it's loaded only for some users. Fixes
Panic: Module context mail_crypt_user_module missing.
- mail_crypt: When LMTP was delivering mails to both recipients with mail
encryption enabled and not enabled, the non-encrypted recipients may
have gotten mails encrypted anyway. This happened when the first
recipient was encrypted (mail_crypt_save_version=2) and the 2nd
recipient was not encrypted (mail_crypt_save_version=0).
- pop3: Session would crash if empty line was sent.
- stats: HTTP server leaked memory.
- submission-login: Long credentials, such as OAUTH2 tokens, were refused
during SASL interactive due to submission server applying line length
limits.
- submission-login: When proxying to remote host, authentication was not
using interactive SASL when logging in using long credentials such as
OAUTH2 tokens. This caused authentication to fail due to line length
constraints in SMTP protocol.
- submission: Terminating the client connection with QUIT command after
mail transaction is started with MAIL command and before it is
finished with DATA/BDAT can cause a segfault crash.
- virtual: doveadm search queries with mailbox-guid as the only parameter
crashes: Panic: file virtual-search.c: line 77 (virtual_search_get_records):
assertion failed: (result != 0)
Pigeonhole v0.5.19
* This release is done to maintain parity with dovecot 2.3.19 release,
so it does not contain any news-worthy changes.
* Thu Feb 03 2022 Michael Ströder <michael@stroeder.com>
- update to 2.3.18 and pigeonhole to 0.5.18
* removed obsolete mail-cache-bigendian.diff
Dovecot 2.3.18
* Removed mail_cache_lookup_finished event. This event wasn't especially
useful, but it increased CPU usage significantly.
* fts: Don't index inline base64 encoded content in FTS indexes using
the generic tokenizer. This reduces the FTS index sizes by removing
input that is very unlikely to be searched for. See
https://doc.dovecot.org/configuration_manual/fts/tokenization for
details on how base64 is detected. Only applies when using libfts.
* lmtp: Session IDs are now preserved through proxied connections, so
LMTP sessions can be tracked. This slightly changes the LMTP session
ID format by appending ":Tn" (transaction), ":Pn" (proxy connection)
and ":Rn" (recipient) counters after the session ID prefix.
+ Events now have "reason_code" field, which can provide a list of
reasons why the event is happening. See
https://doc.dovecot.org/admin_manual/event_reasons/
+ New events are added. See https://doc.dovecot.org/admin_manual/list_of_events/
+ fts: Added fts_header_excludes and fts_header_includes settings to
specify which headers to index. See
https://doc.dovecot.org/settings/plugin/fts-plugin#plugin-fts-setting-fts-header-excludes
for configuration details.
+ fts: Initialize the textcat language detection library only once per
process. This can reduce CPU usage if fts_languages setting has multiple
languages listed and service indexer-worker { service_count } isn't 1.
Only applies when using libfts.
+ lib-storage: Reduced CPU usage significantly for some operations that
accessed lots of emails (e.g. fetching all flags in a folder, SORT, ...)
+ lib: DOVECOT_PREREQ() - Add micro version which enables compiling
external plugins against different versions of Dovecot.
+ lmtp: Added new lmtp_verbose_replies setting that makes errors sent to
the LMTP client much more verbose with details about why exactly
backend proxy connections or commands are failing.
+ submission: Support implicit SASL EXTERNAL with
submission_client_workarounds=implicit-auth-external. This allows
automatically logging in when SSL client certificate is present.
- *-login: Statistics were disabled if stats process connection was lost.
- auth: Authentication master user login fails with SCRAM-* SASL mechanisms.
- auth: With auth_cache_verify_password_with_worker=yes, passdb extra
fields in the auth cache got lost.
- doveadm: Fixed crash if zlib_save_level setting was specified,
but zlib_save was unset. v2.3.15 regression.
- doveadm: Proxying can panic when flushing print output. v2.3.17
regression. Fixes:
Panic: file ioloop.c: line 865 (io_loop_destroy): assertion failed:
(ioloop == current_ioloop)
- doveadm: stats add --group-by parameter didn't work.
- fts: Using email-address fts tokenizer could result in excessive memory
usage with garbage email input. This could cause the indexer-worker
processes to fail due to reaching the VSZ memory size limit.
Only applies when using libfts.
- imap: A SEARCH command timing out while fts returns indexes may timeout
returning "NO [SERVERBUG]", while it should return "NO [INUSE]" instead.
- imap: LIST-EXTENDED doesn't return STATUS for all folders. Sending
LIST .. RETURN (SUBSCRIBED STATUS (...)) did not return STATUS for
folders that are not subscribed when they have a child folder that is
subscribed as mandated by IMAP RFCs.
- imapc: Mailbox vsize calculation crashed with
Panic: file index-mailbox-size.c: line 344 (index_mailbox_vsize_hdr_add_missing):
assertion failed: (mails_left > 0)
- indexer: If indexer-worker crashes, the request it was processing gets
stuck in the indexer process. This stops indexing for the folder until
indexer process is restarted. v2.3.14 regression.
- indexer: Process was slowly leaking memory for each indexing request.
- lib-event: Unnamed events were wrongly filtered out for event/metric
filters like "event=abc OR something_independent_of_event_name".
- lib-index: 64-bit big endian CPUs handle last_used field in
dovecot.index.cache wrong.
- lib-ssl-iostream: Fix buggy OpenSSL error handling without assert-crashing.
If there is no error available, log it as an error instead of crashing.
The previous fix for this in v2.3.11 was incomplete. Fixes
Panic: file istream-openssl.c: line 51 (i_stream_ssl_read_real):
assertion failed: (errno != 0)
- lmtp: Out-of-memory issues can happen when proxying large messages to
LMTP backend servers that accept the message data too slow.
- master: HAProxy header parsing has read buffer overflow if provided
header size is invalid. This happens only if inet_listener
{ haproxy=yes } is configured and only if the remote IP address is in
haproxy_trusted_networks.
- old_stats: Plugin kept increasing memory usage, which became
noticeable with long-running imap sessions.
- stats: Dynamically adding same metric multiple times causes multiple stats.
- submission-login: Authentication does not accept OAUTH2 token (or
other very long credentials) because it considers the line to be too long.
- submission-login: Process can crash if HELO is pipelined with an
invalid domain.
- submission-proxy: Don't use SASL-IR if it would make the AUTH command
line longer than 512 bytes.
- submission: Service would crash if relay server authentication failed.
- virtual: FTS search in a virtual folder could crash if there are
duplicate mailbox GUIDs. This mainly happened when user had both INBOX
and INBOX/INBOX folders and the namespace prefix was INBOX/. Fixes
Panic: file hash.c: line 252 (hash_table_insert_node):
assertion failed: (opcode == HASH_TABLE_OP_UPDATE)
- virtual: If mailbox opening fails, the backend mailbox is leaked and
process crashes when client disconnects. Fixes
Panic: file mail-user.c: line 232 (mail_user_deinit):
assertion failed: ((*user)->refcount == 1)
- virtual: Searching headers in virtual folders didn't always use
full-text search indexes, if fts_enforced=no or body.
Pigeonhole v0.5.18
- duplicate: Users without a home directory can crash with Sieve when
using duplicate database. v2.3.17 regression.
- imapsieve: When mail was expunged when processing imapsieve events, a
crash could occur. Fixes Panic: file mail-index-map.c:
line 558 (mail_index_map_lookup_seq_range): assertion failed: (first_uid > 0)
- managesieve-login: Proxy didn't support forwarding the forward_* passdb fields.
- redirect: Sieve would crash if redirect after keep-equivalent action failed.
- sieve: Interpreter crashes when the Sieve index extension is used with
index zero.
- vnd.dovecot.filter: Envelope sender string may become corrupted when
Sieve scripts are using vnd.dovecot.filter. This could end up
corrupting mbox's From line and return wrong envelope sender string in
* Wed Feb 02 2022 Dominique Leuenberger <dimstar@opensuse.org>
- Fix dovecot-2.3.0-dont_use_etc_ssl_certs.patch: Align the
certificate path/filenames to /etc/ssl/private/*.crt, which
happens to match what the patch also does for mkcert.sh
(boo#1193909).
- Rebase dovecot-2.3.0-better_ssl_defaults.patch
* Thu Dec 16 2021 Fabian Vogt <fvogt@suse.com>
- Update dovecot-2.3.0-dont_use_etc_ssl_certs.patch to also adjust
the path in the 10-ssl.conf example (boo#1193758)
- Rebase dovecot-2.3.0-better_ssl_defaults.patch
* Tue Dec 07 2021 Michael Ströder <michael@stroeder.com>
- update to 2.3.17.1 and pigeonhole to 0.5.17.1
- rebased dovecot-2.3.0-better_ssl_defaults.patch
Dovecot 2.3.17.1
- dsync: Add back accidentically removed parameters.
- lib-ssl-iostream: Fix assert-crash when OpenSSL returned syscall error
without errno.
- master: Dovecot failed to start if ssl_ca was too large.
Dovecot 2.3.17
* Dovecot now logs a warning if time seems to jump forward at least
100 milliseconds.
* dict: Lines logged by the dict process now contain the dict name as
the prefix.
* lib-index: mail_cache_fields, mail_always_cache_fields and
mail_never_cache_fields now verifies that the listed header names are
valid. Especially the UTF8 "–" character has sometimes been wrongly
used instead of the ASCII "-".
+ *-login: Added login_proxy_rawlog_dir setting to capture
rawlogs between proxy and backend.
+ dict: The server process now keeps the last 10 idle dict backends
cached for maximum of 30 seconds. Practically this acts as a
connection pool for dict-redis and dict-ldap. Note that this doesn't
affect dict-sql, because it already had its own internal cache.
+ doveadm: New stats add/remove commands added to support changing the
metrics configuration on runtime.
+ lazy_expunge: Added lazy_expunge_exclude settings to disable
lazy_expunge for specific folders. \Special-use flags can be used as
folder names.
+ lib-lua: Added a new helper function dovecot.restrict_global_variables()
to disable or enable defining new global variables.
- LAYOUT=index List index rebuild was missing.
- LAYOUT=index: Duplicate GUIDs were not detected.
- acl: When using acl_ignore_namespace Dovecot attempted to access or
create dovecot-acl-list even when the namespace should have been
ignored. For virtual namespaces this could have yielded errors about
"Read-only file system" or "Permission denied".
- auth: Setting the "master" passdb field to empty value would
cause proxying to fail with an authentication error.
Now an empty "master" field is ignored.
- doveadm-server: Duplicate error lines were sent for failed commands.
This didn't normally cause visible problems, except when using
wildcards in usernames or -A parameter to go through multiple users.
- doveadm-server: Logs written by doveadm-server were often missing log
prefixes, especially mail_log_prefix for mail commands. Logs sent to
doveadm TCP client were also missing log prefixes.
- doveadm: v2.3 regression: batch command always crashes.
- doveadm: v2.3.11 regression: Commands failed if ssl_cert or
ssl_key files weren't readable by the user running doveadm, even
though doveadm didn't actually use these settings
- imap-hibernate: Process may crash at deinit:
Panic: file ioloop.c: line 928 (io_loop_destroy): assertion failed:
(ioloop->cur_ctx == NULL).
- imap: Using imap_fetch_failure=no-after can cause assert-crash
with some IMAP commands if reading the mail fails (e.g. wrong cached
mail size). Fixes:
Panic: file index-mail-headers.c: line 198 (index_mail_parse_header_init):
assertion failed: (!mail->data.header_parser_initialized)
- imap: v2.3.10 regression: When using INDEXPVT to enable private
\Seen flags (for shared or public namespaces) the STORE command did
not send untagged replies for the \Seen flag changes.
- imap: v2.3.15 regression: If PREVIEW/SNIPPET is not the final FETCH
option in the command, the IMAP FETCH response is broken.
- imap: v2.3.15 regression: MOVE command leaks mailbox if it can't be
opened and crashes at deinit:
Panic: file mail-user.c: line 229 (mail_user_deinit): assertion failed:
((*user)->refcount == 1).
- imapc: Copying nonexistent mail via imapc could have crashed. Fixes:
Panic: file mail-storage.c: line 2385 (mailbox_transaction_commit_get_changes):
assertion failed: (ret < 0 || seq_range_count(&changes_r->saved_uids) == save_count ||
array_count(&changes_r->saved_uids) == 0).
- indexer: v2.3.15 regression: Process crashes if indexer-client
disconnects while it's waiting for command reply. This happened for
example if IMAP SEARCH triggered long fts indexing and the IMAP
client disconnected while waiting for the reply.
- indexer: v2.3.15 regression: Process may have crashed in some situations.
- indexer: v2.3.15 regression: indexer-worker processes may not have
reached the process_limit in some situations, possibly even using just
one indexer-worker process even though there were many indexing
requests queued.
- lib-compression: Reading lz4 compressed mdbox mails may crash. Fixes:
Panic: file istream.c: line 345 (i_stream_read_memarea):
assertion failed: (!stream->blocking).
- lib-compression: bench-compress crashes due to xz being read-only.
- lib-lua: Fix linking libdict_lua for non-GNU linkers when Lua support
is disabled.
- lib-mail: There was no limit on how large an email header name could be.
Processable header names are now limited to 1000 bytes.
- lib-oauth2: Dovecot disallowed JWT tokens if their validity time was
older than token creation time (nbf < iat).
- lib-storage: Reduce memory footprint of certain storage operations.
- lib-storage: When listing mailboxes with storage name escape
characters (^ or .) as part of the mailbox name, the listing could
show corrupted mailbox names. Due to an issue in handling escaped
parent folders, the listing of other mailbox names would become
corrupted by prepending parts of the previously listed mailboxes
parent folder as prefix to the actual mailbox names. The corruption
can occur when using LAYOUT=INDEX and maildir or obox, or when using
the listescape plugin.
- mail-crypt: Fix "-O" argument for "doveadm mailbox cryptokey password"
command to be a boolean, and not expect a string.
- submission-login: Add support for not authenticating to next hop in
submission proxying.
- submission-login: EHLO was not sent again after XCLIENT when doing
submission proxying.
- virtual: Mailboxes do not correctly detect underlying mailboxes
getting re-created even though they have a different UIDVALIDITY or
GUID.
Pigeonhole v0.5.17
- duplicate: The Sieve duplicate test is prone to false negatives when
the user receives many e-mails concurrently, meaning that duplicate
deliveries can still occur.
- fileinto: v2.3.16 regression: Sieve delivery crashes if mail is
delivered to non-existing and existing folder.
- imap-filter-sieve: v2.3.15 regression: The CPU limits on Sieve
execution are too easily exceeded in IMAP context (the IMAPSieve and
FILTER=SIEVE capabilities). Changed the default to unlimited CPU time
for IMAP context, since similar excessive resource usage can be caused
by other means as well. The CPU limits on Sieve scripts executed at
LDA/LMTP delivery are still enforced by default.
- redirect: The Sieve redirect action has protections against users
triggering mail loops. Unfortunately, the detection of a redirect mail
loop sometimes causes the message to get lost if no other Sieve action
is applied that delivers the message somewhere else.
- redirect: v2.3.16 regression: With certain Sieve scripts if redirect
fails due to temporary failure, the lmtp process may crash after the
delivery. Fixes:
Panic: file mail-user.c: line 229 (mail_user_deinit):
assertion failed: ((*user)->refcount == 1).
* Tue Aug 10 2021 Michael Ströder <michael@stroeder.com>
- added back-port fix mail-cache-bigendian.diff
- update to 2.3.16 and pigeonhole to 0.5.16:
Dovecot 2.3.16
* Any unexpected exit() will now result in a core dump. This can
especially help notice problems when a Lua script causes exit(0).
* auth-worker process is now restarted when the number of auth
requests reaches service auth-worker { service_count }. The default
is still unlimited.
+ Event improvements: Added data_stack_grow event and http-client
category. See https://doc.dovecot.org/admin_manual/list_of_events/
+ oauth2: Support RFC 7628 openid-configuration element. This allows
clients to support OAUTH2 for any server, not just a few hardcoded
servers like they do now. See openid_configuration_url setting in
dovecot-oauth2.conf.ext.
+ mysql: Single statements are no longer enclosed with BEGIN/COMMIT.
+ dovecot-sysreport --core supports multiple core files now and does
not require specifying the binary path.
+ imapc: When imap_acl plugin is loaded and imapc_features=acl is used,
IMAP ACL commands are proxied to the remote server. See
https://doc.dovecot.org/configuration_manual/mail_location/imapc/
+ dict-sql now supports the "UPSERT" syntax for SQLite and PostgreSQL.
+ imap: If IMAP client disconnects during a COPY command, the copying
is aborted, and changes are reverted. This may help to avoid many
email duplicates if client disconnects during COPY and retries it
after reconnecting.
- master process was using 100% CPU if service attempted to create more
processes due to process_min_avail, but process_limit was already
reached. v2.3.15 regression.
- Using attachment detection flags wrongly logged unnecessary "Failed
to add attachment keywords" errors. v2.3.13 regression.
- IMAP QRESYNC: Expunging UID 1 mail resulted in broken VANISHED
response, which could have confused IMAP clients. v2.3.13 regression.
- imap: STORE didn't send untagged replies for \Seen changes for
(shared) mailboxes using INDEXPVT. v2.3.10 regression.
- rawlog_dir setting would not log input that was pipelined after
authentication command.
- Fixed potential infinite looping with autoexpunging.
- Log event exporter: Truncate long fields to 1000 bytes
- LAYOUT=index: ACL inheritance didn't work when creating mailboxes
- Event filters: Unquoted '?' wildcard caused a crash at startup
- fs-metawrap: Fix to handling zero sized files
- imap-hibernate: Fixed potential crash at deinit.
- acl: dovecot-acl-list files were written for acl_ignore_namespaces
- program-client (used by Sieve extprograms, director_flush_socket)
may have missed status response from UNIX and network sockets,
resulting in unexpected failures.
Pigeonhole v0.5.16
* .dovecot.sieve.log file now includes year in the header.
* Change Sieve script result execution to delay definitive action
execution to the end of a successful Sieve script execution session.
This is part of an effort to solve problems with the Sieve duplicate
test. As a side-effect, some rare temporary-error cases yield
different results, in which partial failure is more likely.
* Tue Jun 22 2021 Marcus Rueckert <mrueckert@suse.de>
- use lua 5.1 for sle12
* Mon Jun 21 2021 Michael Ströder <michael@stroeder.com>
- update to 2.3.15 and pigeonhole to 0.5.15:
* security fixes for CVE-2021-29157, CVE-2021-33515, and CVE-2020-28200
* rebased patch dovecot-2.3.0-better_ssl_defaults.patch
* removed obsolete back-port patches
allow-tls1.3-only.patch and openssl-cnf-default_bits-2048.patch
* require lua53-devel for build
Dovecot 2.3.15
* CVE-2021-29157: Dovecot does not correctly escape kid and azp fields in
JWT tokens. This may be used to supply attacker controlled keys to
validate tokens, if attacker has local access.
* CVE-2021-33515: On-path attacker could have injected plaintext commands
before STARTTLS negotiation that would be executed after STARTTLS
finished with the client.
* Disconnection log messages are now more standardized across services.
They also always now start with "Disconnected" prefix.
* Dovecot now depends on libsystemd for systemd integration.
* Removed support for Lua 5.2. Use version 5.1 or 5.3 instead.
* config: Some settings are now marked as "hidden". It's discouraged to
change these settings. They will no longer be visible in doveconf
output, except if they have been changed or if doveconf -s parameter
is used. See https://doc.dovecot.org/settings/advanced/ for details.
* imap-compress: Compression level is now algorithm specific.
See https://doc.dovecot.org/settings/plugin/compress-plugin/
* indexer-worker: Convert "Indexed" info logs to an event named
"indexer_worker_indexing_finished". See
https://doc.dovecot.org/admin_manual/list_of_events/#indexer-worker-indexing-finished
+ Add TSLv1.3 support to min_protocols.
+ Allow configuring ssl_cipher_suites. (for TLSv1.3+)
+ acl: Add acl_ignore_namespace setting which allows to entirely ignore
ACLs for the listed namespaces.
+ imap: Support official RFC8970 preview/snippet syntax. Old methods of
retrieving preview information via IMAP commands ("SNIPPET and PREVIEW
with explicit algorithm selection") have been deprecated.
+ imapc: Support INDEXPVT for imapc storage to enable private
message flags for cluster wide shared mailboxes.
+ lib-storage: Add new events: mail_opened, mail_expunge_requested,
mail_expunged, mail_cache_lookup_finished. See
https://doc.dovecot.org/admin_manual/list_of_events/#mail
+ zlib, imap-compression, fs-compress: Support compression levels that
the algorithm supports. Before, we would allow hardcoded value between
1 to 9 and would default to 6. Now we allow using per-algorithm value
range and default to whatever default the algorithm specifies.
- *-login: Commands pipelined together with and just after the authenticate
command cause these commands to be executed twice. This applies to all
protocols that involve user login, which currently comprises of imap,
pop3, submisision and managesieve.
- *-login: Processes are supposed to disconnect the oldest non-logged in
connection when process_limit was reached. This didn't actually happen
with the default "high-security mode" (with service_count=1) where each
connection is handled by a separate process.
- *-login: When login process reaches client/process limits, oldest
client connections are disconnected. If one of these was still doing
anvil lookup, this caused a crash. This could happen only if the login
process limits were very low or if the server was overloaded.
- Fixed building with link time optimizations (-flto).
- auth: Userdb iteration with passwd driver does not always return all
users with some nss drivers.
- dsync: Shared INBOX not synced when "mail_shared_explicit_inbox" was
disabled. If a user has a shared mailbox which is another user's INBOX,
dsync didn't include the mailbox in syncing unless explicit naming is
enabled with "mail_shared_explicit_inbox" set to "yes".
- dsync: Shared namespaces were not synced with "-n" flag.
- dsync: Syncing shared INBOX failed if mail_attribute_dict was not set.
If a user has a shared mailbox that is another user's INBOX, dsync
failed to export the mailbox if mail attributes are disabled.
- fts-solr, fts-tika: Using both Solr FTS and Tika may have caused HTTP
requests to assert-crash: Panic: file http-client-request.c: line 1232
(http_client_request_send_more): assertion failed: (req->payload_input != NULL)
- fts-tika: 5xx errors returned by Tika server as indexing failures.
However, Tika can return 5xx for some attachments every time.
So the 5xx error should be retried once, but treated as success if it
happens on the retry as well. v2.3 regression.
- fts-tika: v2.3.11 regression: Indexing messages with fts-tika may have
resulted in Panic: file message-parser.c: line 802 (message_parser_deinit_from_parts):
assertion failed: (ctx->nested_parts_count == 0 || i_stream_have_bytes_left(ctx->input))
- imap: SETMETADATA could not be used to unset metadata values.
Instead NIL was handled as a "NIL" string. v2.3.14 regression.
- imap: IMAP BINARY FETCH crashes at least on empty base64 body:
Panic: file index-mail-binary.c: line 358 (blocks_count_lines):
assertion failed: (block_count == 0 || block_idx+1 == block_count)
- imap: If IMAP client using the NOTIFY command was disconnected while
sending FETCH notifications to the client, imap could crash with
Panic: Trying to close mailbox INBOX with open transactions.
- imap: Using IMAP COMPRESS extension can cause IMAP connection to hang
when IMAP commands are >8 kB long.
- imapc: If remote server sent BYE but didn't immediately disconnect, it
could cause infinite busy-loop.
- lib-index: Corrupted cache record size in dovecot.index.cache file
could have caused a crash (segfault) when accessing it.
- lib-oauth2: JWT token time validation now works correctly with
32-bit systems.
- lib-ssl-iostream: Checking hostnames against an SSL certificate was
case-sensitive.
- lib-storage: Corrupted mime.parts in dovecot.index.cache may have
resulted in Panic: file imap-bodystructure.c: line 206 (part_write_body):
assertion failed: (text == ((part->flags & MESSAGE_PART_FLAG_TEXT) != 0))
- lib-storage: Index rebuilding (e.g. via doveadm force-resync) didn't
preserve the "hdr-pop3-uidl" header. Because of this, the next pop3
session could have accessed all of the emails' metadata to read their
POP3 UIDL (opening dbox files).
- listescape: When using the listescape plugin and a shared namespace
the plugin didn't work properly anymore resulting in errors like:
"Invalid mailbox name: Name must not have '/' character."
- lmtp: Connection crashes if connection gets disconnected due to
multiple bad commands and the last bad command is BDAT.
- lmtp: The Dovecot-specific LMTP parameter XRCPTFORWARD was blindly
forwarded by LMTP proxy without checking that the backend has support.
This caused a command parameter error from the backend if it was
running an older Dovecot release. This could only occur in more complex
setups where the message was proxied twice; when the proxy generated
the XRCPTFORWARD parameter itself the problem did not occur, so this
only happened when it was forwarded.
- lmtp: The LMTP proxy crashes with a panic when the remote server
replies with an error while the mail is still being forwarded through
a DATA/BDAT command.
- lmtp: Username may have been missing from lmtp log line prefixes when
it was performing autoexpunging.
- master: Dovecot would incorrectly fail with haproxy 2.0.14 service
checks.
- master: Systemd service: Dovecot announces readiness for accepting
connections earlier than it should. The following environment variables
are now imported automatically and can be omitted from
import_environment setting: NOTIFY_SOCKET LISTEN_FDS LISTEN_PID.
- master: service { process_min_avail } was launching processes too
slowly when master was forking a lot of processes.
- util: Make the health-check.sh example script POSIX shell compatible.
Pigeonhole 0.5.15
* CVE-2020-28200: Sieve interpreter is not protected against abusive
scripts that claim excessive resource usage. Fixed by limiting the
user CPU time per single script execution and cumulatively over
several script runs within a configurable timeout period. Sufficiently
large CPU time usage is summed in the Sieve script binary and execution
is blocked when the sum exceeds the limit within that time. The block
is lifted when the script is updated after the resource usage times out.
* Disconnection log messages are now more standardized across services.
They also always now start with "Disconnected" prefix.
- managesieve: Commands pipelined together with and just after the
authenticate command cause these commands to be executed twice.
* Fri May 14 2021 Fabian Vogt <fvogt@suse.com>
- Add patch to fix insecure default openssl.cnf (boo#1184552):
* openssl-cnf-default_bits-2048.patch
- Use %autosetup
* Thu Mar 04 2021 Michael Ströder <michael@stroeder.com>
- update to 2.3.14 and pigeonhole to 0.5.14
* removed obsolete fix-timeval_cmp_margin-for-32bit-systems.patch
Dovecot 2.3.14
* Added new aliases for some variables. Usage of the old ones is possible,
but discouraged. (These were partially added already to v2.3.13.)
See https://doc.dovecot.org/configuration_manual/config_file/config_variables/
for more information.
* Optimize imap/pop3/submission/managesieve proxies to use less CPU at
the cost of extra memory usage.
* Remove autocreate, expire, snarf and mail-filter plugins.
* Remove cydir storage driver.
* Remove XZ/LZMA write support. Read support will be removed in future release.
* doveadm -D: Add timestamps to debug output even when LOG_STDERR_TIMESTAMP
environment variable is not set. Timestamp format is taken from
log_timestamp setting.
* If BROKENCHAR or listescape plugin is used, the escaped folder names
may be slightly different from before in some situations. This is
unlikely to cause issues, although caching clients may redownload the
folders.
* imapc: It now enables BROKENCHAR=~ by default to escape remote folder
names if necessary. This also means that if there are any '~'
characters in the remote folder names, they will be visible as "~7e".
* imapc: When using local index files folder names were escaped on
filesystem a bit differently. This affects only if there are folder
names that actually require escaping, which isn't so common. The old
style folders will be automatically deleted from filesystem.
* stats: Update exported metrics to be compliant with OpenMetrics standard.
+ doveadm: Add an optional '-p' parameter to metadata list command. If
enabled, "/private", and "/shared" metadata prefixes will be prepended
to the keys in the list output.
+ doveconf: Support environment variables in config files. See
https://doc.dovecot.org/configuration_manual/config_file/config_file_syntax/#environment-variables
for more details.
+ indexer-worker: Change indexer to disconnect from indexer-worker
after each request. This allows service indexer-worker's service_count &
idle_kill settings to work. These can be used to restart indexer-worker
processes once in a while to reduce their memory usage.
- auth: "nodelay" with various authentication mechanisms such as apop
and digest-md5 crashed AUTH process if authentication failed.
- auth: Auth lua script generating an error triggered an assertion
failure: Panic: file db-lua.c: line 630 (auth_lua_call_password_verify):
assertion failed: (lua_gettop(script->L) == 0).
- configure: Fix libunwind detection to work on other than x86_64 systems.
- doveadm-server: Process could crash if logging was done outside command
handling. For example http-client could have done debug logging
afterwards, resulting in either segfault or Panic:
file http-client.c: line 642 (http_client_context_close):
assertion failed: (cctx->clients_list == NULL).
- dsync: Folder name escaping with BROKENCHAR didn't work completely
correctly. This especially caused problems with dsync-migrations using
imapc where some of the remote folder names may not have been accessible.
- dsync: doveadm sync + imapc doesn't always sync all mails when doing
an incremental sync (-1), which could lead to mail loss when it's used
for migration. This happens only when GUIDs aren't used (i.e.
imapc without imapc_features=guid-forced).
- fts-tika: When tika server returns error, some mails cause Panic:
file message-parser.c: line 802 (message_parser_deinit_from_parts):
assertion failed: (ctx->nested_parts_count == 0 || i_stream_have_bytes_left(ctx->input))
- lib-imap: imapc parsing illegal BODYSTRUCTUREs with NILs could have
resulted in crashes. This exposed that Dovecot was wrongly accepting
atoms in "nstring" handling. Changed the IMAP parsing to be more
strict about this now.
- lib-index: If dovecot.index.cache has corrupted message size, fetching
BODY/BODYSTRUCTURE may cause assert-crash:
Panic: file index-mail.c: line 1140 (index_mail_parse_body_finish):
assertion failed: (mail->data.parts != NULL).
- lib-index: Minor error handling and race condition fixes related to
rotating dovecot.index.log. These didn't usually cause problems,
unless the log files were rotated rapidly.
- lib-lua: Lua scripts using coroutines or lua libraries using coroutines
(e.g., cqueues) panicked.
- Message PREVIEW handled whitespace wrong so first space would get
eaten from between words.
- FTS and message PREVIEW (snippet) parsed HTML &entities case-sensitively.
- lib-mail: When max nested MIME parts were reached, IMAP BODYSTRUCTURE
was written in a way that may have caused confusion for IMAP clients
and also Dovecot itself when parsing it. The truncated part is now
written out using application/octet-stream MIME type.
- lib-oauth2: HS512 and HS384 JWT token algorithms crash when you try to
use them: Panic: file hmac.c: line 26 (hmac_init): assertion failed:
(meth->context_size <= MAC_MAX_CONTEXT_SIZE).
- event filters: NOT keyword did not have the correct associativity.
NOT a AND b were getting parsed as NOT (a AND b) instead of
(NOT a) AND b.
- Ignore ECONNRESET when closing socket. This avoids logging useless
errors on systems like FreeBSD.
- event filters: event filter syntax error may lead to Panic:
file event-filter.c: line 137 (event_filter_parse): assertion failed:
(state.output == NULL)
- lib: timeval_cmp_margin() was broken on 32-bit systems. This could
potentially have caused HTTP timeouts to be handled incorrectly.
- log: instance_name wasn't used as syslog ident by the log process.
- master: After a service reached process_limit and client_limit, it
could have taken up to 1 second to realize that more client connections
became available. During this time client connections could have been
unnecessarily rejected and a warning logged:
Warning: service(...): process_limit (...) reached, client connections are being dropped
- stats: Crash would occur when generating openmetrics data for metrics
using aggregating functions.
- stats: Event filters comparing against empty strings crash the stats
process.
Pigeonhole 0.5.14

- update to 2.3.13 and pigeonhole to 0.5.13
Dovecot 2.3.13
* CVE-2020-24386: Specially crafted command can cause IMAP hibernate to
allow logged in user to access other people's emails and filesystem
information.
* Metric filter and global event filter variable syntax changed to a
SQL-like format. See
https://doc.dovecot.org/configuration_manual/event_filter/
* auth: Added new aliases for %{variables}. Usage of the old ones is
possible, but discouraged.
* auth: Removed RPA auth mechanism, SKEY auth mechanism, NTLM auth
mechanism and related password schemes.
* auth: Removed passdb-sia, passdb-vpopmail and userdb-vpopmail.
* auth: Removed postfix postmap socket
+ auth: Added new fields for auth server events. These fields are now
also available for all auth events. See
https://doc.dovecot.org/admin_manual/list_of_events/#authentication-server
for details.
+ imap-hibernate: Added imap_client_hibernated, imap_client_unhibernated
and imap_client_unhibernate_retried events. See
https://doc.dovecot.org/admin_manual/list_of_events/ for details.
+ lib-index: Added new mail_index_recreated event. See
https://doc.dovecot.org/admin_manual/list_of_events/#mail-index-recreated
+ lib-sql: Support TLS options for cassandra driver. This requires
cpp-driver v2.15 (or later) to work reliably.
+ lib-storage: Missing $HasAttachment / $HasNoAttachment flags are now
added to existing mails if mail_attachment_detection_option=add-flags
and it can be done inexpensively.
+ login proxy: Added login_proxy_max_reconnects setting (default 3) to
control how many reconnections are attempted.
+ login proxy: imap/pop3/submission/managesieve proxying now supports
reconnection retrying on more than just connect() failure. Any error
except a non-temporary authentication failure will result in reconnect
attempts.
- auth: Lua passdb/userdb leaks stack elements per call, eventually
causing the stack to become too deep and crashing the auth or
auth-worker process.
- auth: SASL authentication PLAIN mechanism could be used to trigger
read buffer overflow. However, this doesn't seem to be exploitable in
any way.
- auth: v2.3.11 regression: GSSAPI authentication fails because dovecot
disallows NUL bytes for it.
- dict: Process used too much CPU when iterating keys, because each key
used a separate write() syscall.
- doveadm-server: Crash could occur if logging was done outside command
handling. For example http-client could have done debug logging
afterwards, resulting in either segfault or
Panic: file http-client.c: line 642 (http_client_context_close):
assertion failed: (cctx->clients_list == NULL).
- doveadm-server: v2.3.11 regression: Trying to connect to doveadm server
process via starttls assert-crashed if there were no ssl=yes listeners:
Panic: file master-service-ssl.c: line 22 (master_service_ssl_init):
assertion failed: (service->ssl_ctx_initialized).
- fts-solr: HTTP requests may have assert-crashed:
Panic: file http-client-request.c: line 1232
(http_client_request_send_more):
assertion failed: (req->payload_input != NULL)
- imap: IMAP NOTIFY could crash with a segmentation fault due to a bad
configuration that causes errors. Sending the error responses to the
client can cause the segmentation fault. This can for example happen
when several namespaces use the same mail storage location.
- imap: IMAP NOTIFY used on a shared namespace that doesn't actually
exist (e.g. public namespace for a nonexistent user) can crash with a
panic:
Panic: Leaked view for index /tmp/home/asdf/mdbox/dovecot.list.index:
Opened in (null):0
- imap: IMAP session can crash with QRESYNC extension if many changes
are done before asking for expunged mails since last sync.
- imap: Process might hang indefinitely if client disconnects after
sending some long-running commands pipelined, for example FETCH+LOGOUT.
- lib-compress: Mitigate crashes when configuring a not compiled in
compression. Errors with compression configuration now distinguish
between not supported and unknown.
- lib-compression: Using xz/lzma compression in v2.3.11 could have
written truncated output in some situations. This would result in
"Broken pipe" read errors when trying to read it back.
- lib-compression: zstd compression could have crashed in some situations:
Panic: file ostream.c: line 287 (o_stream_sendv_int): assertion
failed: (!stream->blocking)
- lib-dict: dict client could have crashed in some rare situations when
iterating keys.
- lib-http: Fix several assert-crashes in HTTP client.
- lib-index: v2.3.11 regression: When mails were expunged at the same
time as lots of new content was being saved to the cache (e.g. cache
file was lost and is being re-filled) a deadlock could occur with
dovecot.index.cache / dovecot.index.log.
- lib-index: v2.3.11 regression: dovecot.index.cache file was being
purged (rewritten) too often when it had a field that hadn't been
accessed for over 1 month, but less than 2 months. Every cache file
change caused a purging in this situation.
- lib-mail: MIME parts were not returned correctly by Dovecot MIME parser.
Regression caused by fixing CVE-2020-12100.
- lib-mail: When max nested MIME parts were reached, IMAP BODYSTRUCTURE
was written in a way that may have caused confusion for both IMAP
clients and Dovecot itself when parsing it. The truncated part is now
written out using application/octet-stream MIME type.
- lib-mail: v2.3.11 regression: Mail delivery / parsing crashed when the
10000th MIME part was message/rfc822 (or if parent was multipart/digest):
Panic: file message-parser.c: line 167 (message_part_append):
assertion failed: (ctx->total_parts_count <= ctx->max_total_mime_parts).
- lib-oauth2: Dovecot incorrectly required oauth2 server introspection
reply to contain username with invalid token.
- lib-ssl-iostream, lib-dcrypt: Fix building with OpenSSL that has
deprecated APIs disabled.
- lib-storage: When mail's size is different from the cached one (in
dovecot.index.cache or Maildir S=size in the filename), this is
handled by logging "Cached message size smaller/larger than expected"
error. However, in some situations this also ended up crashing with:
Panic: file istream.c: line 315 (i_stream_read_memarea):
assertion failed: (old_size <= _stream->pos - _stream->skip).
- lib-storage: v2.3 regression: Copying/moving mails was taking much more
memory than before. This was mainly visible when copying/moving
thousands of mails in a single transaction.
- lib-storage: v2.3.11 regression: Searching messages assert-crashed
(without FTS): Panic: file message-parser.c: line 174
(message_part_finish):
assertion failed: (ctx->nested_parts_count > 0).
- lib: Dovecot v2.3 moved signal handlers around in ioloops,
causing more CPU usage than in v2.2.
- lib: Fixed JSON parsing: '\' escape sequence may have wrongly resulted
in error if it happened to be at read boundary. Any NUL characters and
'\u0000' will now result in parsing error instead of silently
truncating the data.
- lmtp, submission: Server may hang if SSL client connection disconnects
during the delivery. If this happened repeated, it could have ended
up reaching process_limit and preventing any further lmtp/submission
deliveries.
- lmtp: Proxy does not always properly log TLS connection problems as
errors; in some cases, only a debug message is logged if enabled.
- lmtp: The LMTP service can hang when commands are pipelined. This can
particularly occur when one command in the middle of the pipeline fails.
One example of this occurs for proxied LMTP transactions in which the
final DATA or BDAT command is pipelined after a failing RCPT command.
- login-proxy: The login_source_ips setting has no effect, and therefore
the proxy source IPs are not cycled through as they should be.
- master: Process was using 100% CPU in some situations when a broken
service was being throttled.
- pop3-login: POP3 login would fail with "Input buffer full" if the
initial response for SASL was too long.
- stats: Crash would occur when generating openmetrics data for metrics
using aggregating functions.
Pigeonhole 0.5.13
- duplicate: The test was handled badly in a multiscript (sieve_before,
sieve_after) scenario in which an earlier script in the sequence with
a duplicate test succeeded, while a later script caused a runtime
failure. In that case, the message is recorded for duplicate tracking,
while the message may not actually have been delivered in the end.
- editheader: Sieve interpreter entered infinite loop at startup when
the "editheader" configuration listed an invalid header name. This
problem can only be triggered by the administrator.
- relational: The Sieve relational extension can cause a segfault at
compile time. This is triggered by invalid script syntax. The segfault
happens when this match type is the last argument of the test command.
This situation is not possible in a valid script; positional arguments
are normally present after that, which would prevent the segfault.
- sieve: For some Sieve commands the provided mailbox name is not
properly checked for UTF-8 validity, which can cause assert crashes at
runtime when an invalid mailbox name is encountered. This can be
caused by the user by writing a bad Sieve script involving the
affected commands ("mailboxexists", "specialuse_exists").
This can be triggered by the remote sender only when the user has
written a Sieve script that passes message content to one of the
affected commands.
- sieve: Large sequences of 8-bit octets passed to certain Sieve
commands that create or modify message headers that allow UTF-8 text
(vacation, notify and addheader) can cause the delivery or IMAP
process (when IMAPSieve is used) to enter a memory-consuming
semi-infinite loop that ends when the process exceeds its memory
limits. Logged in users can cause these hangs only for their own
processes.

Dovecot 2.3.11.3
- pop3-login: Login didn't handle commands in multiple IP packets properly.
This mainly affected large XCLIENT commands or a large SASL initial
response parameter in the AUTH command.
- pop3: pop3_deleted_flag setting was broken, causing:
Panic: file seq-range-array.c: line 472 (seq_range_array_invert):
assertion failed: (range[count-1].seq2 <= max_seq)
Dovecot 2.3.11.2
- auth: Lua passdb/userdb leaks stack elements per call, eventually
causing the stack to become too deep and crashing the auth or
auth-worker process.
- lib-mail: v2.3.11 regression: MIME parts not returned correctly by
Dovecot MIME parser.
- pop3-login: Login would fail with "Input buffer full" if the initial
response for SASL was too long.
Dovecot 2.3.11
* CVE-2020-12100: Parsing mails with a large number of MIME parts could
have resulted in excessive CPU usage or a crash due to running out of
stack memory.
* CVE-2020-12673: Dovecot's NTLM implementation does not correctly check
message buffer size, which leads to reading past allocation which can
lead to crash.
* CVE-2020-10967: lmtp/submission: Issuing the RCPT command with an
address that has the empty quoted string as local-part causes the lmtp
service to crash.
* CVE-2020-12674: Dovecot's RPA mechanism implementation accepts
zero-length message, which leads to assert-crash later on.
* Events: Fix inconsistency in events. See event documentation in
https://doc.dovecot.org.
* imap_command_finished event's cmd_name field now contains "unknown"
for unknown commands. A new "cmd_input_name" field contains the
command name exactly as it was sent.
* lib-index: Renamed mail_cache_compress_* settings to mail_cache_purge_*.
Note that these settings are mainly intended for testing and usually
shouldn't be changed.
* events: Renamed "index" event category to "mail-index".
* events: service:<name> category is now using the name from
configuration file.
* dns-client: service dns_client was renamed to dns-client.
* log: Prefixes generally use the service name from configuration file.
For example dict-async service will now use
"dict-async(pid): " log prefix instead of "dict(pid): "
* *-login: Changed logging done by proxying to use a consistent prefix
containing the IP address and port.
* *-login: Changed disconnection log messages to be slightly clearer.
+ dict: Add events for dictionaries.
+ lib-index: Finish logging with events.
+ oauth2: Support local validation of JWT tokens.
+ stats: Add support for dynamic histograms and grouping. See
https://doc.dovecot.org/configuration_manual/stats/.
+ imap: Implement RFC 8514: IMAP SAVEDATE
+ lib-index: If a long-running transaction (e.g. SORT/FETCH on a huge
folder) adds a lot of data to dovecot.index.cache file, commit those
changes periodically to make them visible to other concurrent sessions
as well.
+ stats: Add OpenMetrics exporter for statistics. See
https://doc.dovecot.org/configuration_manual/stats/openmetrics/.
+ stats: Support disabling stats-writer socket by setting
stats_writer_socket_path="".
- auth-worker: Process keeps slowly increasing its memory usage and
eventually dies with "out of memory" due to reaching vsz_limit.
- auth: Prevent potential timing attacks in authentication secret
comparisons: OAUTH2 JWT-token HMAC, imap-urlauth token, crypt() result.
- auth: Several auth-mechanisms allowed input to be truncated by NUL
which can potentially lead to unintentional issues or even successful
logins which should have failed.
- auth: When auth policy returned a delay, auth_request_finished event
had policy_result=ok field instead of policy_result=delayed.
- auth: auth process crash when auth_policy_server_url is set to an
invalid URL.
- dict-ldap: Crash occurs if var_expand template expansion fails.
- dict: If dict client disconnected while iteration was still running,
dict process could have started using 100% CPU, although it was still
handling clients.
- doveadm: Running doveadm commands via proxying may hang, especially
when doveadm is printing a lot of output.
- imap: "MOVE * destfolder" goes to a loop copying the last mail to the
destination until the imap process dies due to running out of memory.
- imap: Running "UID MOVE 1:* Trash" on an empty folder goes to infinite
loop.
- imap: SEARCH doesn't support $.
- lib-compress: Buffer over-read in zlib stream read.
- lib-dns: If DNS lookup times out, lib-dns can cause crash in calling
process.
- lib-index: Fixed several bugs in dovecot.index.cache handling that
could have caused cached data to be lost.
- lib-index: Writing to >=1 GB dovecot.index.cache files may cause
assert-crashes:
Panic: file mail-index-util.c: line 37 (mail_index_uint32_to_offset):
assertion failed: (offset < 0x40000000)
- lib-ssl-iostream: Fix buggy OpenSSL error handling without
assert-crashing. If there is no error available, log it as an error
instead of crashing:
Panic: file iostream-openssl.c: line 599 (openssl_iostream_handle_error):
assertion failed: (errno != 0)
- lib-ssl-iostream: ssl_key_password setting did not work.
- submission: A segfault crash may occur when the client or server
disconnects while a non-transaction command like NOOP or VRFY is still
being processed.
- virtual: Copying/moving mails with IMAP into a virtual folder assert-crashes:
Panic: file cmd-copy.c: line 152 (fetch_and_copy): assertion failed:
(copy_ctx->copy_count == seq_range_count(©_ctx->saved_uids))
Pigeonhole 0.5.11
* managesieve: managesieve_max_line_length setting is now a "size" type
instead of just number of bytes. This allows using e.g. "64k" as the
value.
- lib-sieve: When folding white space is used in the Message-ID header,
it is not stripped away correctly before the message ID value is used,
causing e.g. garbled log lines at delivery.
* Tue May 19 2020 Marcus Rueckert <mrueckert@suse.de>
- update tls 1.3 patch to allow building with tls 1.0
* Mon May 18 2020 Michael Ströder <michael@stroeder.com>

sending a NOOP command with an invalid string parameter.
(boo#1171457)
* CVE-2020-10958: lmtp/submission: Sending many invalid or unknown
commands can cause the server to access freed memory, which can lead
to a server crash. (boo#1171458)
* CVE-2020-10967: lmtp/submission: Issuing the RCPT command with an
address that has the empty quoted string as local-part causes the
lmtp service to crash. (boo#1171456)

- add allow-tls1.3-only.patch:
Allow setting TLSv1.3 as minimum TLS version
https://github.com/dovecot/core/pull/126
* Fri Mar 06 2020 Arjen de Korte <suse+build@de-korte.org>
- update to 2.3.10 and pigeonhole to 0.5.10
Dovecot 2.3.10
* Disable retpoline migitations by default. These can cause severe
performance regressions, so they should be only enabled when
applicable.
* IMAP MOVE now commits transactions in batches of 1000 mails. This
helps especially with lazy_expunge when moving a lot of mails. It
mainly avoids situations where multiple IMAP sessions are running the
same MOVE command and duplicating the mails in the lazy_expunge folder.
With this change there can still be some duplication, but the MOVE
always progresses forward. Also if the MOVE fails at some point, the
changes up to the last 1000 mails are still committed instead of
rolled back. Note that the COPY command behavior hasn't changed,
because it is required by IMAP standard to be an atomic operation.
* IMAP EXPUNGE and CLOSE now expunges mails in batches of 1000 mails.
This helps especially with lazy_expunge when expunging a lot of mails
(e.g. millions) to make sure that the progress always moves forward
even if the process is killed.
* Autoexpunging now expunges mails in batches of 1000 mails. This helps
especially with lazy_expunge when expunging a lot of mails
(e.g. millions) to make sure that the progress always moves forward
even if the process is killed.
+ Add tool for generating sysreport called dovecot-sysreport.
This generates a bundle of information usually needed for support
requests.
+ Add support for the new IMAP \Important SPECIAL-USE flag (RFC 8457).
+ Add metric { group_by } setting. This allows automatically creating
new metrics based on the fields you want to group statistics by.
NOTE: This feature is considered experimental and syntax is subject
to change in future release.
+ auth: Support SCRAM-SHA-256 authentication mechanism.
+ imap: Support the new IMAP STATUS=SIZE extension.
+ Use TCP_QUICKACK to reduce latency for some TCP connections.
+ quota-status: Made the service more robust against erroneous use with
Postfix ACL policies other than smtpd_recipient_restrictions.
+ Add "revision" field support to imap_id_send setting. Using
"revision *" will send in IMAP ID command response the short commit
hash of the Dovecot git source tree HEAD (same as in dovecot --version).
+ IMAP ENVELOPE includes now all addresses when there are multiple
headers (From, To, Cc, etc.) The standard way of having multiple
addresses is to just list them all in a single header. It's
non-standard to have multiple headers. However, since MTAs allow these
mails to pass through and different software may handle them in
different ways, it's better from security point of view to show all
the addresses.
+ Event filters now support using "field_name=" to match a field that
doesn't exist or has an empty value. For example use "error=" to match
only events that didn't fail.
- acl: INBOX ACLs shouldn't apply for IMAP GETMETADATA/SETMETADATA
commands.
- cassandra: CASS_ERROR_SERVER_WRITE_FAILURE error should also be
treated as "uncertain write failure".
- dict-redis: Using quota_clone configured with dict-redis could have
crashed when Redis responded slowly.
- fts-solr: The XML response parser fails to parse large/chunked responses
correctly. This leads to spurious parse errors, most notably: "Error:
fts_solr: received invalid uid '0'".
- imap-hibernate: Communication trouble with imap-master leads to
segfault.
- imap-hibernate: Unhibernation retrying wasn't working.
- imap: Fixed auth lookup privilege problem when imap process was reused
and user was being un-hibernated.
- Fix potential crash when copying/moving mails within the same folder.
This happened only when there were a lot of fields in dovecot.index.cache.
- lib-index: Recreating dovecot.index.cache file could have crashed when
merging bitmask fields.
- lib-index: Using public/shared folders with INDEXPVT configured to use
private \Seen flags, trying to search seen/unseen in an empty folder
crashes with segfault.
- lib-mail: Large base64-encoded mails weren't decoded properly.
This could have affected searching/indexing mails and message snippet
generation.
- lib-mail: Message with only quoted text could have caused message
snippet to ignore its 200 character limit and return the entire
message. This was added also to dovecot.index.cache file, which
increased disk space and memory usage unnecessarily.
v2.3.9.2 regression (previous versions cached the quoted snippet as
empty). In a large mail quoted text could have become wrongly added
to the snippet, possibly mixed together with non-quoted text.
- lib-smtp: client could have assert-crashed if STARTTLS handshake
finished earlier than usually.
- lib-ssl-iostream: remove -static flag for lib-ssl-iostream linking to
prevent a compile issue.
- lib-storage: Mailbox synchronization may have assert-crashed in some
rare situations.
- lib-storage: mdbox didn't preserve date.saved with dsync.
- lib: Don't require EAI_{ADDRFAMILY,NODATA}, breaks FreeBSD
- master: Some services could respawn unthrottled if they crash during
startup.
- push-notification: Do not send push_notification_finished event if
nothing was done. This happens when mail transaction is started and
ended with no changes.
- quota-status: Addresses with special characters in the local part caused
problems in the interaction between Postfix and Dovecot. Postfix sent
its own internal representation in the recipient field, while Dovecot
expected a valid RFC5321 mailbox address.
- submission-login: SESSION was not correctly encoded field for the
XCLIENT command. Particularly, a '+' character introduced by the
session ID's Base64 encoding causes problems.
- submission: Fix submission_max_mail_size to work correctly on 32-bit
systems.
- submission: Trusted connections crashed in second connection's EHLO
if submission-login { service_count } is something else than 1 (which
is the default).
- submission: XCLIENT command was never used in the protocol exchange
with the relay MTA when submission_backend_capabilities is configured,
even when the relay MTA was properly configured to accept the XCLIENT
command.
Pigeonhole 0.5.10
* imap_sieve_filter: Change result action logging to include IMAP UID
- vacation: Addresses were compared case-sensitively.
* Wed Feb 26 2020 Dominique Leuenberger <dimstar@opensuse.org>
- Update dovecot-2.3.0-dont_use_etc_ssl_certs.patch: since we
change CERTDIR to /etc/ssl/private, it is rather evil to then err
out claiming /etc/ssl/certs would not exist. The error message
should mention the directory it tested for.
* Wed Feb 12 2020 Arjen de Korte <suse+build@de-korte.org>
- update to 2.3.9.3
* CVE-2020-7046: Truncated UTF-8 can be used to DoS
submission-login and lmtp processes.
* CVE-2020-7957: Specially crafted mail can crash snippet generation.
* Sun Dec 22 2019 Peter Varkoly <varkoly@suse.com>
- Adapt package changes in mysql-devel
* Sat Dec 14 2019 Michael Ströder <michael@stroeder.com>
- update to 2.3.9.2 with security fixes:
* CVE-2019-19722: Mails with group addresses in From or To
fields caused crash in push notification drivers.
* Mails with empty From/To headers can also cause crash
in push notification drivers.
* Wed Dec 04 2019 Michael Ströder <michael@stroeder.com>
- update to 2.3.9 and pigeonhole to 0.5.9
Dovecot 2.3.9
* Changed several event field names for consistency and to avoid
conflicts in parent-child event relationships:
* SMTP server command events: Renamed "name" to "cmd_name"
* Events inheriting from a mailbox: Renamed "name" to "mailbox"
* Server connection events have only "remote_ip", "remote_port",
"local_ip" and "local_port".
* Removed duplicate "client_ip", "ip" and "port".
* Mail storage events: Removed "service" field.
Use "service:<name>" category instead.
* HTTP client connection events: Renamed "host" to "dest_host" and
"port" to "dest_port"
* auth: Drop Postfix socketmap support. It hasn't been working
with recent Postfix versions for a while now.
* push-notification-lua: The "subject" field is now decoded to UTF8
instead of kept as MIME-encoded.
+ push-notification-lua: Added new "from_address", "from_display_name",
"to_address" and "to_display_name" fields. The display names are
decoded to UTF8.
+ Added various new fields to existing events.
See http://doc.dovecot.net/admin_manual/list_of_events.html
+ Add lmtp_add_received_header setting. It can be used to prevent LMTP
from adding "Received:" headers.
+ doveadm: Support SSL/STARTTLS for proxied doveadm connections based on
doveadm_ssl setting and proxy ssl/tls settings.
+ Log filters support now "service:<name>", which matches all events for
the given service. It can also be used as a category.
+ lib: Use libunwind to get abort backtraces with function names
where available.
+ lmtp: When the LMTP proxy changes the username (from passdb lookup)
add an appropriate ORCPT parameter.
- lmtp: Add lmtp_client_workarounds setting to implement workarounds for
clients that send MAIL and RCPT commands with additional spaces before
the path and for clients that omit <> brackets around the path.
See example-config/conf.d/20-lmtp.conf.
- lda/lmtp: Invalid MAIL FROM addresses were rejcted too aggressively.
Now mails from addresses with unicode characters are delivered, but
their Return-Path header will be <> instead of the given MAIL FROM
address.
- lmtp: The lmtp_hdr_delivery_address setting is ignored.
- imap: imap_command_finished event's "args" and "human_args" parameters
were always empty.
- mbox: Seeking in zlib and bzip2 compressed input streams didn't work
correctly.
- imap-hibernate: Process crashed when client got destroyed while it was
attempted to be unhibernated, and the unhibernation fails.
- *-login: Proxying may have crashed if SSL handshake to the backend
failed immediately. This was unlikely to happen in normal operation.
- *-login: If TLS handshake to upstream server failed during proxying,
login process could crash due to invalid memory access.
- *-login: v2.3 regression: Using SASL authentication without initial
response may have caused SSL connections to hang. This happened often
at least with PHP's IMAP library.
- *-login: When login processes are flooded with authentication attempts
it starts logging errors about "Authentication server sent unknown id".
This is still expected. However, it also caused the login process to
disconnect from auth server and potentially log some user's password
in the error message.
- dict-sql: SQL prepared statements were not shared between sessions.
This resulted in creating a lot of prepared statements, which was
especially inefficient when using Cassandra backend with a lot of
Cassandra nodes.
- auth: auth_request_finished event didn't have success=yes parameter
set for successful authentications.
- auth: userdb dict - Trying to list users crashed.
- submission: Service could be configured to allow anonymous
authentication mechanism and anonymous user access.
- LAYOUT=index: Corrupted dovecot.list.index caused folder creation to
panic.
- doveadm: HTTP server crashes if request target starts with double "/".
- dsync: Remote dsync started hanging if the initial doveadm
"dsync-server" command was sent in the same TCP packet as the
following dsync handshake. v2.3.8 regression.
- lib: Several "input streams" had a bug that in some rare situations
might cause it to access freed memory. This could lead to crashes or
corruption.
The only currently known effect of this is that using zlib plugin with
external mail attachments (mail_attachment_dir) could cause fetching
the mail to return a few bytes of garbage data at the beginning of the
header. Note that the mail wasn't saved corrupted, but fetching it
caused corrupted mail to be sent to the client.
- lib-storage: If a mail only has quoted content, use the quoted text
for generating message snippet (IMAP PREVIEW) instead of returning
empty snippet.
- lib-storage: When vsize header was rebuilt, newly calculated message
sizes were added to dovecot.index.cache instead of being directly
saved into vsize records in dovecot.index.
- lib: JSON generator was escaping UTF-8 characters unnecessarily.
Pigeonhole 0.5.8
+ Added events for Sieve and ManageSieve, see
https://doc.dovecot.org/admin_manual/list_of_events/#pigeonhole
+ Pigeonhole: Implement the Sieve "special-use" extension described in
RFC 8579.
- duplicate: Test only compared the handles which would cause
different values to be cached as the same duplicate test. Fix to also
compare the actual hashes.
- imap_sieve_filter: IMAP FILTER Command had various bugs in error
handling. Errors may have been duplicated for each email, errors
may have been missing entirely, command tag and ERRORS/WARNINGS
parameters were swapped.
* Fri Nov 08 2019 Arjen de Korte <suse+build@de-korte.org>
- Disable Link Time Optimization (LTO) (boo#1156301)
* Tue Oct 08 2019 Michael Ströder <michael@stroeder.com>
- update to 2.3.8 and pigeonhole to 0.5.8
Dovecot 2.3.8
+ Added mail_delivery_started and mail_delivery_finished events, see
https://doc.dovecot.org/admin_manual/list_of_events/ for details.
+ dsync-replication: Don't replicate users who have "noreplicate" extra
field in userdb.
+ doveadm service status: Show total number of processes created.
+ When logging to syslog, use instance_name setting's value for the
ident. This commonly is added as a log prefix.
+ Base64 encoding/decoding code was rewritten with additional features.
It shouldn't cause any user visible changes.
- v2.3.7 regression: If a folder only receives new mails without any
other mail access, dovecot.index.log keeps growing forever and
dovecot.index keeps being rewritten for every mail delivery.
- dsync-replication may lose keywords after syncing mails restored from
another replica. This only happened if the mail only had keywords and
no system flags.
- event filters: Non-textual event fields could not be filtered using
wildcards.
- auth: Scope parameter was missing from OAuth password grant
request.
- doveadm client-server communication may hang in some situations.
It is also using unnecessarily small TCP/IP packet sizes.
- doveadm who and kick did not flush protocol output correctly.
- imap: SETMETADATA with literal value would delete the metadata value
instead of updating it.
- imap: When client issues FETCH PREVIEW (LAZY=FUZZY) command, the
caching decisions should be updated so that newly saved mails will
have the preview cached.
- With mail_nfs_index=yes and/or mail_nfs_storage=yes setuid/setgid
permission bits in some files may have become dropped with some NFS
servers. Changed NFS flushing to now use chmod() instead of chown().
- quota: warnings did not work if quota root was noenforcing
- acl: Global ACL file ignored the last line if it didn't end with LF.
- doveadm stats dump: With JSON formatter output numbers using the
number type instead of as strings
- lmtp_proxy: Ensure that real_* variables are correctly set when using
lmtp_proxy.
- event exporter: http-post driver had hardcoded timeout and did not
support DNS lookups or TLS connections.
- auth: Fix user iteration to work with userdb passwd with glibc v2.28.
- auth: auth service can crash if auth-policy JSON response is invalid
or returned too fast.
- In some rare situations "ps" output could have shown a lot of "?"
characters after Dovecot process titles.
- When dovecot.index.pvt is empty, an unnecessary error is logged:
Error: .../dovecot.index.pvt reset, view is now inconsistent
- SMTP address encoder duplicated initial double quote character when
the localpart of an address ended in '..'. For example
"user+..@example.com" became ""user+.."@example.com in a
sieve redirect.
Pigeonhole 0.5.8
- Sieve may leak resources in rare cases when a redirect, vacation or
report action fails to send the message. This mainly applies when
Sieve is executed in IMAP context; i.e., for the IMAPSIEVE or
FILTER=SIEVE capabilities.
* Wed Aug 28 2019 Marcus Rueckert <mrueckert@suse.de>

+ SNIPPET is now PREVIEW and size has been increased to 200 characters.
+ Add body option to fts_enforced. This triggers building FTS index only
on body search, and an error using FTS index fails the search rather
than reads through all the mails.
- Submission/LMTP: Fixed crash when domain argument is invalid in a
second EHLO/LHLO command.
- Copying/moving mails using Maildir format loses IMAP keywords in the
destination if the mail also has no system flags.
- mail_attachment_detection_options=add-flags-on-save caused email body
to be unnecessarily opened when FETCHing mail headers that were
already cached.
- mail attachment detection keywords not saved with maildir.
- dovecot.index.cache may have grown excessively large in some
situations. This happened especially when using autoexpunging with
lazy_expunge folders. Also with mdbox format in general the cache file
wasn't recreated as often as it should have.
- Autoexpunged mails weren't immediately deleted from the disk. Instead,
the deletion from disk happened the next time the folder was opened.
This could have caused unnecessary delays if the opening was done by
an interactive IMAP session.
- Dovecot's TCP connections sometimes add extra 40ms latency due to not
enabling TCP_NODELAY. HTTP and SMTP/LMTP connections weren't
affected, but everything else was. This delay wasn't always visible -
only in some situations with some message/packet sizes.
- imapc: Fix various crash conditions
- Dovecot builds were not always reproducible.
- login-proxy: With shutdown_clients=no after config reload the
existing connections could no longer be listed or kicked with doveadm.
- "doveadm proxy kick" with -f parameter caused a crash in some
situations.
- Auth policy can cause segmentation fault crash during auth process
shutdown if all auth requests have not been finished.
- Fix various minor bugs leading into incorrect behaviour in mailbox
list index handling. These rarely caused noticeable problems.
- LDAP auth: Iteration accesses freed memory, possibly crashing
auth-worker
- local_name { .. } filter in dovecot.conf does not correctly support
multiple names and wildcards were matched incorrectly.
- replicator: dsync assert-crashes if it can't connect to remote TCP
server.
- config: Memory leak in config process when ssl_dh setting wasn't
set and there was no ssl-parameters.dat file.
This caused config process to die once in a while
with "out of memory".

during upgrade
* Tue Apr 30 2019 Marcus Rueckert <mrueckert@suse.de>
- update pigeonhole to 0.5.6
+ sieve: Redirect loop prevention is sometimes ineffective.
Improve existing loop detection by also recognizing the
X-Sieve-Redirected-From header in incoming messages and
dropping redirect actions when it points to the sending
account. This header is already added by the redirect action,
so this improvement only adds an additional use of this header.
- sieve: Prevent execution of implicit keep upon temporary
failure occurring at runtime.
* Tue Apr 30 2019 Marcus Rueckert <mrueckert@suse.de>
- update to 2.3.6: (boo#1133624 boo#1133625)

disconnecting.
* CVE-2019-11499: Submission-login crashed when authentication
was started over TLS secured channel and invalid authentication
message was sent.
* auth: Support password grant with passdb oauth2.
+ Use system default CAs for outbound TLS connections.
+ Simplify array handling with new helper macros.
+ fts_solr: Enable configuring batch_size and soft_commit features.
- lmtp/submission: Fixed various bugs in XCLIENT handling,
including a hang when XCLIENT commands were sent infinitely to
the remote server.
- lmtp/submission: Forwarded multi-line replies were erroneously
sent as two replies to the client.
- lib-smtp: client: Message was not guaranteed to contain CRLF
consistently when CHUNKING was used.
- fts_solr: Plugin was no longer compatible with Solr 7.
- Make it possible to disable certificate checking without
setting ssl_client_ca_* settings.
- pop3c: SSL support was broken.
- mysql: Closing connection twice lead to crash on some systems.
- auth: Multiple oauth2 passdbs crashed auth process on deinit.
- HTTP client connection errors infrequently triggered a
segmentation fault when the connection was idle and not used
for a particular client instance.

[PATCH] driver-mysql: Avoid double-closing MySQL connection
* Thu Apr 18 2019 Marcus Rueckert <mrueckert@suse.de>
- update to 2.3.5.2 (boo#1132501)
* CVE-2019-10691: Trying to login with 8bit username containing
invalid UTF8 input causes auth process to crash if auth policy
is enabled. This could be used rather easily to cause a DoS.
Similar crash also happens during mail delivery when using
invalid UTF8 in From or Subject header when OX push
notification driver is used.
* Thu Mar 28 2019 Marcus Rueckert <mrueckert@suse.de>
- update to 2.3.5.1 (boo#1130116)
* CVE-2019-7524: Missing input buffer size validation leads into
arbitrary buffer overflow when reading fts or pop3 uidl header
from Dovecot index. Exploiting this requires direct write
access to the index files.
* Fri Mar 08 2019 Marcus Rueckert <mrueckert@suse.de>
- update to 2.3.5
+ Lua push notification driver: mail keywords and flags are
provided in MessageNew and MessageAppend events.
+ submission: Implement support for plugins.
+ auth: When auth_policy_log_only=yes, only log what the policy
server response would do without actually doing it.
+ auth: Always log policy server decisions with auth_verbose=yes
- v2.3.[34]: doveadm log errors: Output was missing user/session
- lda: Debug log lines could have shown slightly corrupted
- login proxy: Login processes may have crashed in various ways
when login_proxy_max_disconnect_delay was set.
- imap: Fix crash with Maildir+zlib if client disconnects during
APPEND
- lmtp proxy: Fix potential assert-crash
- lmtp/submission: Fix crash when SMTP client transaction times
out
- submission: Split large XCLIENT commands to 512 bytes per
command, so Postfix accepts them.
- submission: Fix crash when client sends invalid BURL command
- submission: relay backend: VRFY command: Avoid forwarding 500
and 502 replies back to client.
- lib-http: Fix potential assert-crash when DNS lookup fails
- lib-fts: Fix search query generation when one language ignores
a token (e.g. via stopwords).
- update pigeonhole to 0.5.5
+ IMAPSieve: Add new plugin/imapsieve_expunge_discarded setting
which causes messages discarded by an IMAPSieve script to be
expunged immediately, rather than only being marked as
"\Deleted" (which is still the default behavior).
- IMAPSieve: Fix panic crash occurring when a COPY command copies
messages from a virtual mailbox where the source messages
originate from more than a single real mailbox.
- imap4flags extension: Fix deleting all keywords. When the
action resulted in all keywords being removed, no changes were
actually applied.
- variables extension: Fix truncation of UTF-8 variable content.
The maximum size of Sieve variables was enforced by truncating
the variable string content bluntly at the limit, but this does
not consider UTF-8 code point boundaries. This resulted in
broken UTF-8 strings. This problem also surfaced for variable
modifiers, such as the ":encodeurl" modifier provided by the
Sieve "enotify" extension. In that case, the resulting URI
escaping could also be truncated inappropriately.
- IMAPSieve, IMAP FILTER=SIEVE: Fix replacing a modified message.
Sieve scripts running in IMAPSIEVE or IMAP FILTER=SIEVE context
that modify the message, stored the message a second time,
rather than replacing the originally stored unmodified message.
- Fix segmentation fault occurring when both the
sieve_extprograms plugin (for the Sieve interpreter) and the
imap_filter_sieve plugin (for IMAP) are loaded at the same
time. A symbol was defined by both plugins, causing a clash
when both were loaded.
- drop patches which were backports

* Tue Feb 05 2019 Marcus Rueckert <mrueckert@suse.de>
- update to 2.3.4.1 (boo#1123022)
* CVE-2019-3814: If imap/pop3/managesieve/submission client has
trusted certificate with missing username field
(ssl_cert_username_field), under some configurations Dovecot
mistakenly trusts the username provided via authentication
instead of failing.
* ssl_cert_username_field setting was ignored with external
SMTP AUTH, because none of the MTAs (Postfix, Exim) currently
send the cert_username field. This may have allowed users with
trusted certificate to specify any username in the
authentication. This bug didn't affect Dovecot's Submission
service.
* Thu Jan 17 2019 Arjen de Korte <suse+build@de-korte.org>

Fix build failures on TW i586
* Sat Nov 24 2018 Marcus Rueckert <mrueckert@suse.de>
- update to 2.3.4
* The default postmaster_address is now "postmaster@<user domain
or server hostname>". If username contains the @domain part,
that's used. If not, then the server's hostname is used.
* "doveadm stats dump" now returns two decimals for the "avg"
field.
+ Added push notification driver that uses a Lua script
+ Added new SQL, DNS and connection events.
See https://wiki2.dovecot.org/Events
+ Added "doveadm mailbox cache purge" command.
+ Added events API support for Lua scripts
+ doveadm force-resync -f parameter performs "index fsck" while
opening the index. This may be useful to fix some types of
broken index files. This may become the default behavior in a
later version.
- director: Kicking a user crashes if login process is very slow
- pop3_no_flag_updates=no: Don't expunge DELEted and RETRed
messages unless QUIT is sent.
- auth: Fix crypt() segfault with glibc-2.28+
- imap: Running UID FILTER script with errors assert-crashes
- dsync, pop3-migration: POP3 UIDLs weren't added to
dovecot.index.cache while mails were saved.
- dict clients may have been using 100% CPU while waiting for
dict server to finish commands.
- doveadm user: Fixed user listing via HTTP API
- All levels of Cassandra log messages were logged as Dovecot
errors.
- http/smtp client may have crashed after SSL handshake
- Lua auth converted strings that looked like numbers into
numbers.
- update pigeonhole to 0.5.4
* Adjustments to several changes in Dovecot v2.3.4 make this
Pigeonhole release dependent on that Dovecot release; it will
not compile against older Dovecot versions. And, conversely,
you need to upgrade Pigeonhole when upgrading Dovecot to
v2.3.4.
* The changes regarding the default postmaster_address in Dovecot
v2.3.4 mainly apply to Pigeonhole. The new default should work
for all existing installations, thereby fixing several reported
v2.3/v0.5 migration problems.
- IMAP FILTER=SIEVE capability: Fix assert crash occurring when running
UID FILTER on a Sieve script with errors.
* Mon Oct 01 2018 Marcus Rueckert <mrueckert@suse.de>
- update pigeonhole to 0.5.3
- Fix assertion panic occurring when managesieve service fails to
open INBOX while saving a Sieve script. This was caused by a
lack of cleanup after failure.
- Fix specific messages causing an assert panic with actions that
compose a reply (e.g. vacation). With some rather weird input
from the original message, the header folding algorithm (as
used for composing the References header for the reply) got
confused, causing the panic.
- IMAP FILTER=SIEVE capability: Fix FILTER SIEVE SCRIPT command
parsing. After finishing reading the Sieve script, the command
parsing sometimes didn't continue with the search arguments.
This is a time- critical bug that likely only occurs when the
Sieve script is sent in the next TCP frame.
* Mon Oct 01 2018 Marcus Rueckert <mrueckert@suse.de>
- update to 2.3.3
* doveconf hides more secrets now in the default output.
* ssl_dh setting is no longer enforced at startup. If it's not
set and non-ECC DH key exchange happens, error is logged and
client is disconnected.
+ Added log_debug=<filter> setting.
+ Added log_core_filter=<log filter> setting.
+ quota-clone: Write to dict asynchronously
+ --enable-hardening attempts to use retpoline Spectre 2
mitigations
+ lmtp proxy: Support source_ip passdb extra field.
+ doveadm stats dump: Support more fields and output stddev
by default.
+ push-notification: Add SSL support for OX backend.
- NUL bytes in mail headers can cause truncated replies when
fetched.
- director: Conflicting host up/down state changes may in some
rare situations ended up in a loop of two directors constantly
overwriting each others' changes.
- director: Fix hang/crash when multiple doveadm commands are
being handled concurrently.
- director: Fix assert-crash if doveadm disconnects too early
- virtual plugin: Some searches used 100% CPU for many seconds
- dsync assert-crashed with acl plugin in some situations.
- mail_attachment_detection_options=add-flags-on-save
assert-crashed with some specific Sieve scripts.
- Mail snippet generation crashed with mails containing invalid
Content-Type:multipart header.

- quota: With noenforcing option current quota usage wasn't
updated.
- auth: Kerberos authentication against Samba assert-crashed.

while handling a command.
- quota: Fixed compiling with glibc-2.26 / support libtirpc.
- fts-solr: Empty search values resulted in 400 Bad Request
errors
- fts-solr: default_ns parameter couldn't be used
- submission server crashed if relay server returned over 7 lines
in a reply (e.g. to EHLO)

* Sat Jun 30 2018 mrueckert@suse.de
- update to 2.3.2
* old-stats plugin: Don't temporarily enable PR_SET_DUMPABLE
while opening /proc/self/io. This may still cause security
problems if the process is ptrace()d at the same time.
Instead, open it while still running as root.
+ doveadm: Added mailbox cache decision&remove commands. See
doveadm-mailbox(1) man page for details.
+ doveadm: Added rebuild attachments command for rebuilding
$HasAttachment or $HasNoAttachment flags for matching mails.
See doveadm-rebuild(1) man page for details.

+ submission: Add support for rawlog_dir
+ submission: Add submission_client_workarounds setting.
+ lua auth: Add password_verify() function and additional fields
in auth request.
- doveadm-server: TCP connections are hanging when there is a lot
of network output. This especially caused hangs in
dsync-replication.
- Using multiple type=shared mdbox namespaces crashed
- mail_fsync setting was ignored. It was always set to
"optimized".
- lua auth: Fix potential crash at deinit
- SSL/TLS servers may have crashed if client disconnected during
handshake.
- SSL/TLS servers: Don't send extraneous certificates to client
when alt certs are used.
- lda, lmtp: Return-Path header without '<' may have
assert-crashed.
- lda, lmtp: Unencoded UTF-8 in email address headers may
assert-crash
- lda: -f parameter didn't allow empty/null/domainless address
- lmtp, submission: Message size limit was hardcoded to 40 MB.
Exceeding it caused the connection to get dropped during
transfer.
- lmtp: Fix potential crash when delivery fails at DATA stage
- lmtp: login_greeting setting was ignored
- Fix to work with OpenSSL v1.0.2f
- systemd unit restrictions were too strict by default
- Fix potential crashes when a lot of log output was produced
- SMTP client may have assert-crashed when sending mail
- IMAP COMPRESS: Send "end of compression" marker when
disconnecting.
- cassandra: Fix consistency=quorum to work
- dsync: Lock file generation failed if home directory didn't
exist
- Snippet generation for HTML mails didn't ignore &entities
inside blockquotes, producing strange looking snippets.
- imapc: Fix assert-crash if getting disconnected and after
reconnection all mails in the selected mailbox are gone.
- pop3c: Handle unexpected server disconnections without
assert-crash
- fts: Fixes to indexing mails via virtual mailboxes.
- fts: If mails contained NUL characters, the text around it
wasn't indexed.
- Obsolete dovecot.index.cache offsets were sometimes used.
Trying to fetch a field that was just added to cache file may
not have always found it.
- update pigeonhole to 0.5.2
+ Implement plugin for the a vendor-defined IMAP capability
called "FILTER=SIEVE". It adds the ability to manually invoke
Sieve filtering in IMAP. More information can be found in
doc/plugins/imap_filter_sieve.txt.
- The Sieve addess test caused an assertion panic for invalid
addresses with UTF-8 codepoints in the localpart. Fixed by
properly detecting invalid addresses with UTF-8 codepoints in
the localpart and skipping these like other invalid addresses
while iterating addresses for the address test.
- Make the length of the subject header for the vacation response
configurable and enforce the limit in UTF-8 codepoints rather
than bytes. The subject header for a vacation response was
statically truncated to 256 bytes, which is too limited for
multi-byte UTF-8 characters.
- Sieve editheader extension: Fix assertion panic occurring when
it is used to manipulate a message header with a very large
header field.
- Properly abort execution of the sieve_discard script upon
error. Before, the LDA Sieve plugin attempted to execute the
sieve_discard script when an error occurs. This can lead to the
message being lost.
- Fix the interaction between quota and the sieve_discard script.
When quota was used together with a sieve_discard script, the
message delivery did not bounce when the quota was exceeded.

- editheader extension: Corrected the stream position
calculations performed while making the modified message
available as a stream. Pigeonhole Sieve crashed in LMTP with
an assertion panic when the Sieve editheader extension was used
before the message was redirected. Experiments indicate that
the problem occurred only with LMTP and that LDA is not
affected.
- fileinto extension: Fix assert panic occurring when fileinto is
used without being listed in the require line, while the copy
extension is listed there. This is a very old bug.
- imapsieve plugin: Do not assert crash or log an error for
messages that disappear concurrently while applying Sieve
scripts. This event is now logged as a debug message.
- Sieve extprograms plugin: Large output from "execute" command
crashed delivery. Fixed buffering issue in code that handles
output from the external program.

$HasAttachment and $HasNoAttachment keywords are set for mails.
+ imap: Support fetching body snippets using FETCH (SNIPPET) or
(SNIPPET (LAZY=FUZZY))
+ fs-compress: Automatically detect whether input is compressed
or not. Prefix the compression algorithm with "maybe-" to
enable the detection, for example: "compress:maybe-gz:6:..."
+ Added settings to change dovecot.index* files' optimization
behavior. See https://wiki2.dovecot.org/IndexFiles#Settings

attacker uses randomly generated SNI servernames. (boo#1082828)
* CVE-2017-14461: Parsing invalid email addresses may cause a
crash or leak memory contents to attacker. For example, these
memory contents might contain parts of an email from another
user if the same imap process is reused for multiple users.
First discovered by Aleksandar Nikolic of Cisco Talos.
Independently also discovered by "flxflndy" via HackerOne.

* Wed Dec 20 2017 mrueckert@suse.de
- starting 2.3 package based on the latest 2.2 branch
There are several new and exciting features in v2.3.0. I'm
especially happy about the new logging and statistics code, which
will allow us to generate statistics for just about everything.
We didn't have time to implement everything we wanted for them
yet, and there especially aren't all that many logging events yet
that can be used for statistics. We'll implement those to v2.3.1,
which might also mean that some of the APIs might still change in
v2.3.1 if that's required.
We also have new lib-smtp server code, which was used to
implement SMTP submission server and do a partial rewrite for
LMTP server.
Some of the larger changes:
* Various setting changes, see
https://wiki2.dovecot.org/Upgrading/2.3
If you upgrade from 2.2: Config file changes:
- Removed:
/etc/dovecot/conf.d/11-object-storage.conf
- Added:

* Logging rewrite started: Logging is now based on hierarchical
events. This makes it possible to do various things, like: 1)
giving consistent log prefixes, 2) enabling debug logging with
finer granularity, 3) provide logs in more machine readable
formats (e.g. json). Everything isn't finished yet, especially
a lot of the old logging code still needs to be translated to
the new way.
* Statistics rewrite started: Stats are now based on (log)
events. It's possible to gather statistics about any event
that is logged. See http://wiki2.dovecot.org/Statistics for
details
* ssl_dh setting replaces the old generated ssl-parameters.dat
* IMAP: When BINARY FETCH finds a broken mails, send [PARSE]
error instead of [UNKNOWNCTE]
* Linux: core dumping via PR_SET_DUMPABLE is no longer enabled
by default due to potential security reasons (found by cPanel
Security Team).
+ Added support for SMTP submission proxy server, which

- Input streams are more reliable now when there are errors or
when the maximum buffer size is reached. Previously in some
situations this could have caused Dovecot to try to read
already freed memory.
- Output streams weren't previously handling failures when
writing a trailer at the end of the stream. This mainly
affected encrypt and zlib compress ostreams, which have
silently written truncated files if the last write happened to
fail (which shouldn't normally have ever happened).
- virtual plugin: Fixed panic when fetching mails from virtual
mailboxes with IMAP BINARY extension.
- doveadm-server: Fix potential hangs with SSL connections
- doveadm proxy: Reading commands' output from v2.2.33+ servers
could have caused the output to be corrupted or caused a
crash.
- Many other smaller fixes
- patches:
- dovecot-2.3.0-better_ssl_defaults.patch
- dovecot-2.3.0-dont_use_etc_ssl_certs.patch
