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).
