Description: This update for dovecot24 fixes the following issues: - Update dovecot to 2.4.2: - CVE-2025-30189: Fixed users cached with same cache key when auth cache was enabled (bsc#1252839) - Changes - auth: Remove proxy_always field. - config: Change settings history parsing to use python3. - doveadm: Print table formatter - Print empty values as "-". - imapc: Propagate remote error codes properly. - lda: Default mail_home=$HOME environment if not using userdb lookup - lib-dcrypt: Salt for new version 2 keys has been increased to 16 bytes. - lib-dregex: Add libpcre2 based regular expression support to Dovecot, if the library is missing, disable all regular expressions. This adds libpcre2-32 as build dependency. - lib-oauth2: jwt - Allow nbf and iat to point 1 second into future. - lib: Replace libicu with our own unicode library. Removes libicu as build dependency. - login-common: If proxying fails due to remote having invalid SSL cert, don't reconnect. - New features - auth: Add ssl_client_cert_fp and ssl_client_cert_pubkey_fp fields - config: Add support for $SET:filter/path/setting. - config: Improve @group includes to work with overwriting their settings. - doveadm kick: Addsupport for kicking multiple usernames - doveadm mailbox status: Add support for deleted status item. - imap, imap-client: Add experimental partial IMAP4rev2 support. - imap: Implement support for UTF8=ACCEPT for APPEND - lib-oauth2, oauth2: Add oauth2_token_expire_grace setting. - lmtp: lmtp-client - Support command pipelining. - login-common: Support local/remote blocks better. - master: accept() unix/inet connections before creating child process to handle it. This reduces timeouts when child processes are slow to spawn themselves. - Bug fixes - SMTPUTF8 was accepted even when it wasn't enabled. - auth, *-login: Direct logging with -L parameter was not working. - auth: Crash occured when OAUTH token validation failed with oauth2_use_worker_with_mech=yes. - auth: Invalid field handling crashes were fixed. - auth: ldap - Potential crash could happen at deinit. - auth: mech-gssapi - Server sending empty initial response would cause errors. - auth: mech-winbind - GSS-SPNEGO mechanism was erroneously marked as - not accepting NUL. - config: Multiple issues with $SET handling has been fixed. - configure: Building without LDAP didn't work. - doveadm: If source user didn't exist, a crash would occur. - imap, pop3, submission, imap-urlauth: USER environment usage was broken when running standalone. - imap-hibernate: Statistics would get truncated on unhibernation. - imap: "SEARCH MIMEPART FILENAME ENDS" command could have accessed memory outside allocated buffer, resulting in a crash. - imapc: Fetching partial headers would cause other cached headers to be cached empty, breaking e.g. imap envelope responses when caching to disk. - imapc: Shared namespace's INBOX mailbox was not always uppercased. - imapc: imapc_features=guid-forced GUID generation was not working correctly. - lda: USER environment was not accepted if -d hasn'tbeen specified. - lib-http: http-url - Significant path percent encoding through parse and create was not preserved. This is mainly important for Dovecot's Lua bindings for lib-http. - lib-settings: Crash would occur when using %variables in SET_FILE type settings. - lib-storage: Attachment flags were attempted to be added for readonly mailboxes with mail_attachment_flags=add-flags. - lib-storage: Root directory for unusable shared namespaces was unnecessarily attempted to be created. - lib: Crash would occur when config was reloaded and logging to syslog. - login-common: Crash might have occured when login proxy was destroyed. - sqlite: The sqlite_journal_mode=wal setting didn't actually do anything. - Many other bugs have been fixed. - Update pigeonhole to 2.4.2 - Changes - lib-sieve: Use new regular expression library in core. - managesieve: Add default service_extra_groups=$SET:default_internal_group. - New features - lib-sieve: Add support for "extlists" extension. - lib-sieve: regex - Allow unicode comparator. - Bug fixes - lib-sieve-tool: sieve-tool - All sieve_script settings were overriden. - lib-sieve: storage: dict: sieve_script_dict filter was missing from settings. - sieve-ldap-storage: Fix compile without LDAP.
