Debian Security Advisory

DLA-1494-1 gdm3 -- LTS security update

Date Reported:

05 Sep 2018

Affected Packages:

gdm3

Vulnerable:

Yes

Security database references:

In Mitre's CVE dictionary: CVE-2018-14424.

More information:

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.
