- update to 2.3.11.3 and pigeonhole to 0.5.11
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.

- 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.

- 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.

Dovecot 2.3.7
* fts-solr: Removed break-imap-search parameter
+ Added more events for the new statistics, see
https://doc.dovecot.org/admin_manual/list_of_events/
+ mail-lua: Add IMAP metadata accessors, see
https://doc.dovecot.org/admin_manual/lua/
+ Add event exporters that allow exporting raw events to log files and
external systems, see
https://doc.dovecot.org/configuration_manual/event_export/
+ 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".
