Recommended update for postfix

SUSE Recommended Update: Recommended update for postfix
Announcement ID: SUSE-RU-2018:2378-1
Rating: moderate
References: #1087471 #1094965
Affected Products:
  • SUSE Linux Enterprise Module for Server Applications 15
  • SUSE Linux Enterprise Module for Basesystem 15

  • An update that has two recommended fixes can now be installed.

    Description:

    This update for postfix fixes the following issues:

    - Postfix version update to 3.3.1 (bsc#1094965)
    * Postfix did not support running as a PID=1 process, which complicated
    Postfix deployment in containers. The "postfix start-fg" command will
    now run the Postfix master daemon as a PID=1 process if possible.
    Thanks for inputs from Andreas Schulze, Eray Aslan, and Viktor
    Dukhovni.
    * Segfault in the postconf(1) command after it could not open a Postfix
    database configuration file due to a file permission error
    (dereferencing a null pointer). Reported by Andreas Hasenack, fixed by
    Viktor Dukhovni.
    * The luser_relay feature became a black hole, when the luser_relay
    parameter was set to a non-existent local address (i.e. mail
    disappeared silently). Reported by J?rgen Thomsen.
    * Missing error propagation in the tlsproxy(8) daemon could result in a
    segfault after TLS handshake error (dereferencing a 0xffff...ffff
    pointer). This daemon handles the TLS protocol when a non-whitelisted
    client sends a STARTTLS command to postscreen(8).
