[SECURITY] [DLA 1494-1] gdm3 security update



Package        : gdm3
Version        : 3.14.1-7+deb8u1
CVE ID         : CVE-2018-14424

The daemon in GDM 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.

For Debian 8 "Jessie", this problem has been fixed in version
3.14.1-7+deb8u1.

We recommend that you upgrade your gdm3 packages.
