SUSE SLED12 / SLES12 Security Update : gdm (SUSE-SU-2018:2527-1)

Medium 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.
