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>

https://github.com/dovecot/core/commit/4ff4bd024a9b6e7973b76b186ce085c2ca669d3e.patch
-------------------------------------------------------------------
Wed Jul 11 14:17:57 UTC 2018 - mrueckert@suse.de
- update to 2.3.2.1
- SSL/TLS servers may have crashed during client disconnection
- lmtp: With lmtp_rcpt_check_quota=yes mail deliveries may have
sometimes assert-crashed.
- v2.3.2: "make check" may have crashed with 32bit systems
-------------------------------------------------------------------
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
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.
- refreshed to apply cleanly again dovecot-2.3.0-better_ssl_defaults.patch

Wed Mar 28 09:02:33 UTC 2018 - mrueckert@suse.de
- update pigeonhole to 0.5.1
- Explicitly disallow UTF-8 in localpart in addresses parsed from
Sieve script.
- 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.
-------------------------------------------------------------------
Tue Mar 27 18:28:48 UTC 2018 - mrueckert@suse.de
- update to 2.3.1
* Submission server support improvements and bug fixes
- Lots of bug fixes to submission server
* API CHANGE: array_idx_modifiable will no longer allocate space
- Particularly affects how you should check MODULE_CONTEXT
result, or use REQUIRE_MODULE_CONTEXT.
+ mail_attachment_detection_options setting controls when
$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
+ Auth cache can now utilize auth workers to do password hash
verification by setting
auth_cache_verify_password_with_worker=yes.
+ Added charset_alias plugin. See
https://wiki2.dovecot.org/Plugins/CharsetAlias
+ imap_logout_format and pop3_logout_format settings now support
all of the generic variables (e.g. %{rip}, %{session}, etc.)
+ Added auth_policy_check_before_auth,
auth_policy_check_after_auth and auth_policy_report_after_auth
settings.
+ master: Support HAProxy PP2_TYPE_SSL command and set "secured"
variable appropriately

- lmtp: Fix crash when user is over quota
- lib-lda: Parsing Return-Path header address fails when it
contains CFWS
- auth: SASL with Exim fails for AUTH commands without an initial
response

* 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
login process. (boo#1075608)
* Linux: Core dumping is no longer enabled by default via
PR_SET_DUMPABLE, because this may allow attackers to bypass
chroot/group restrictions. Found by cPanel Security Team.
Nowadays core dumps can be safely enabled by using "sysctl -w
fs.suid_dumpable=2". If the old behaviour is wanted, it can
still be enabled by setting:
import_environment=$import_environment PR_SET_DUMPABLE=1
- imap-login with SSL/TLS connections may end up in infinite loop

- 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 could 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
