Dirk Mueller 21a5cd0499 Accepting request 784360 from home:adkorte:branches:server:mail 
- 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 12:40:54 UTC 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.

-------------------------------------------------------------------
Sat Dec 14 08:55:56 UTC 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 4 21:46:28 UTC 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.

-------------------------------------------------------------------
Tue Oct 8 17:31:00 UTC 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.

- update to 2.3.7.1 and pigeonhole to 0.5.7.1
Dovecot 2.3.7.1
- Fix TCP_NODELAY errors being logged on non-Linux OSes
- lmtp proxy: Fix assert-crash when client uses BODY=8BITMIME
- Remove wrongly added checks in namespace prefix checking
Pigeonhole 0.5.7.1
- dsync: Sieve script syncing failed if mailbox attributes weren't enabled.
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".

Tue Apr 30 13:49:18 UTC 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.

[PATCH] driver-mysql: Avoid double-closing MySQL connection
-------------------------------------------------------------------
Thu Apr 18 11:40:06 UTC 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 12:36:55 UTC 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 8 18:09:00 UTC 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 5 13:45:52 UTC 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.

-------------------------------------------------------------------
Sat Nov 24 00:27:59 UTC 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 1 22:55:38 UTC 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 1 22:54:12 UTC 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.

-------------------------------------------------------------------
Sat Jun 30 20:06:40 UTC 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

- 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.

* CVE-2017-15130: TLS SNI config lookups may lead to excessive
memory usage, causing imap-login/pop3-login VSZ limit to be
reached and the process restarted. This happens only if Dovecot
config has local_name { } or local { } configuration blocks and
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.
(boo#1082826)
* CVE-2017-15132: Aborted SASL authentication leaks memory in

- 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:
/etc/dovecot/conf.d/20-submission.conf
* 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
includes support for BURL and CHUNKING extension.
+ LMTP rewrite. Supports now CHUNKING extension and mixing of
local/proxy recipients.
+ auth: Support libsodium to add support for ARGON2I and
ARGON2ID password schemes.
+ auth: Support BLF-CRYPT password scheme in all platforms
+ auth: Added LUA scripting support for passdb/userdb.
See https://wiki2.dovecot.org/AuthDatabase/Lua
- 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
