   An update that solves two vulnerabilities, contains one
   feature and has one errata is now available.

Description:

   This update for dovecot23 fixes the following issues:

   Update dovecot to version 2.3.15 (jsc#SLE-19970):

   Security issues fixed:

   - 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. (bsc#1187418) Local
     attacker can login as any user and access their emails
   - CVE-2021-33515:  On-path attacker could have injected plaintext commands
     before STARTTLS negotiation that would be executed after STARTTLS
     finished with the client. (bsc#1187419) Attacker can potentially steal
     user credentials and mails

   * 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-indexin
     g-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.
   * 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.
   - 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.
   * 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-https: 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.

   Update pigeonhole to version 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.
     (bsc#1187420) Attacker can DoS the mail delivery system (jsc#PM-2746)
     ECO: Dovecot 2.3.15 version upgrade
   * 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.
   * 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.
