openSUSE Security Update: Security update for gdm Announcement ID: openSUSE-SU-2018:2818-1 Rating: m
An update that solves one vulnerability and has two fixes is now available.

Description

This update for gdm provides the following fixes:

This security issue was fixed:

- 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)

These non-security issues were fixed:

- Enable pam_keyinit module (bsc#1081947)

- Fix a build race in SLE (bsc#1103093)

This update was imported from the SUSE:SLE-15:Update update project.
