Debian DLA-1494-1 : gdm3 security update
High Nessus Plugin ID 117295
SynopsisThe remote Debian host is missing a security update.
DescriptionThe 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.
NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
SolutionUpgrade the affected packages.
