The package changes :

Updated 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.

dovecot23 was updated 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

  - 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.
    (bsc#1119850)

  - mail_attachment_detection_options=add-flags-on-save     assert-crashed with some specific Sieve scripts.

  - Log prefix ordering was different for some log lines.

  - quota: With noenforcing option current quota usage     wasn't updated.

  - auth: Kerberos authentication against Samba     assert-crashed.

  - stats clients were unnecessarily chatty with the stats     server.

  - imapc: Fixed various assert-crashes when reconnecting to     server.

  - 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

dovecot was updated 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.

  - cassandra: Use fallback_consistency on more types of     errors

  - lmtp proxy: Support outgoing SSL/TLS connections

  - lmtp: Add lmtp_rawlog_dir and lmtp_proxy_rawlog_dir     settings.

  - 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.

pigeonhole was updated 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.

  - Fix crash for over quota users

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

It was discovered that there was a vulnerability in the dovecot IMAP/POP3 server.

A flaw in the TLS username handling could lead to an attacker logging in as anyone else in the system if both auth_ssl_{require_client,username_from}_cert were enabled.

For Debian 8 'Jessie', this issue has been fixed in dovecot version 1:2.2.13-12~deb8u5.

We recommend that you upgrade your dovecot packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

It was discovered that Dovecot incorrectly handled client certificates. A remote attacker in possession of a valid certificate with an empty username field could possibly use this issue to impersonate other users.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Aki Tuomi (Open-Xchange Oy) reports :

Normally Dovecot is configured to authenticate imap/pop3/managesieve/submission clients using regular username/password combination. Some installations have also required clients to present a trusted SSL certificate on top of that. It's also possible to configure Dovecot to take the username from the certificate instead of from the user provided authentication. It's also possible to avoid having a password at all, only trusting the SSL certificate.

If the provided trusted SSL certificate is missing the username field, Dovecot should be failing the authentication. However, the earlier versions will take the username from the user provided authentication fields (e.g. LOGIN command). If there is no additional password verification, this allows the attacker to login as anyone else in the system.

This affects only installations using :

auth_ssl_require_client_cert = yes auth_ssl_username_from_cert = yes

Attacker must also have access to a valid trusted certificate without the ssl_cert_username_field in it. The default is commonName, which almost certainly exists in all certificates. This could happen for example if ssl_cert_username_field is a field that normally doesn't exist, and attacker has access to a web server's certificate (and key), which is signed with the same CA.

Attack can be migitated by having the certificates with proper Extended Key Usage, such as 'TLS Web Server' and 'TLS Web Server Client'.

Also, 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 does not apply to Dovecot Submission service.

halfdog discovered an authentication bypass vulnerability in the Dovecot email server. Under some configurations Dovecot mistakenly trusts the username provided via authentication instead of failing. If there is no additional password verification, this allows the attacker to login as anyone else in the system. Only installations using :

  - auth_ssl_require_client_cert = yes
  - auth_ssl_username_from_cert = yes

are affected by this flaw.
