Monday 21st June 2021

Fedora Project

  • Updated perl-Mixin-Linewise to 0.109 in Rawhide:

    • Use "-r" test instead of "-f" test, to allow use on (say) named pipes

    • Update author information
    • Add perl support section to docs

  • Updated perl-Sub-Exporter to 0.988 in Rawhide:

    • Update author contact info
    • Add perl support section to docs

Local Packages

  • Cleaned up and rebuilt perl-File-MMagic (1.30) as per the Fedora version

  • Updated perl-Mixin-Linewise to 0.109 as per the Fedora version; the new version uses syntax like this: 

  • package Mixin::Linewise 0.109;
  • instead of the older syntax: 
  • package Mixin::Linewise;
$Mixin::Linewise::VERSION = '0.108';
  • The RPM dependency generators prior to Fedora 21 and RHEL 8 do not understand this new syntax so I had to add manual provides for builds on older distributions

  • Updated perl-Module-CoreList to 5.20210620:

    • Updated for v5.35.1

  • Updated perl-Net-Telnet to 3.05:

    • Improved the speed of waitfor() to search for the "match", especially when reading a large amount of data, by using the dynamic arrays @- and @+ instead of $` and $&

    • Changed the logging subroutines to also accept a tied filehandle

    • Fixed new perl warning about argument isn't numeric in numeric ge (>=)

  • Updated perl-Sub-Exporter to 0.988 as per the Fedora version

Tuesday 22nd June 2021

Fedora Project

Local Packages

  • Updated dovecot (2.3):

    • Updated dovecot to 2.3.15:

      • CVE-2021-29157: Dovecot does not correctly escape kid and azp fields in JWT tokens, which may be used to supply attacker controlled keys to validate tokens, if attacker has local access

      • CVE-2021-33515: On-path attacker could have injected plaintext commands before STARTTLS negotiation that would be executed after STARTTLS finished with the client

      • 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" and it's discouraged to change these settings; they will no longer be visible in doveconf output, except if they have been changed or if the 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-indexing-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 and 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, submission 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, though it 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 was 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

    • Updated pigeonhole to 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, and the block is lifted when the script is updated after the resource usage times out

      • 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

  • Updated proftpd (1.3.7b) as per the Fedora version
