An update that solves three vulnerabilities and has one security fix can now be installed.

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).
