  script_tag(name:"insight", value:"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.

     + 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

  Description truncated. Please see the references for more information.");
