   An update that solves three vulnerabilities and has one
   errata is now available.

Description:

   This update for systemd fixes the following issues:

   * Fix security vulnerabilities CVE-2018-16864 and CVE-2018-16865
     (bsc#1120323): Both issues were memory corruptions via
     attacker-controlled alloca which could have been used to gain root
     privileges by a local attacker.

   * Fix security vulnerability CVE-2018-15686 (bsc#1113665): A vulnerability
     in unit_deserialize of systemd used to allow an attacker to supply
     arbitrary state across systemd re-execution via NotifyAccess. This could
     have been used to improperly influence systemd execution and possibly
     lead to root privilege escalation.

   * Remedy 2048 character line-length limit in systemd-sysctl code that
     would cause parser failures if /etc/sysctl.conf contained lines that
     exceeded this length (bsc#1071558).

   * Fix a bug in systemd's core timer code that would cause timer looping
     under certain conditions, resulting in hundreds of syslog messages being
     written to the journal (bsc#1068588).
