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)
