High Nessus Plugin ID 112146

Synopsis

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

Description

This update for gdm fixes the following security issue :

- CVE-2018-14424: The daemon in GDM did not properly unexport display objects from its D-Bus interface when they are destroyed, which allowed a local attacker to trigger a use-after-free via a specially crafted sequence of D-Bus method calls, resulting in a denial of service or potential code execution (bsc#1103737).

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.
