CVE-2018-14424

Priority
Description
The daemon in GDM through 3.29.1 does not properly unexport display objects
from its D-Bus interface when they are destroyed, which allows 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.
