high Nessus Plugin ID 121061

Language:

Synopsis

The remote SUSE host is missing one or more security updates.

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).

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
