- Date Reported:
- 05 Sep 2018
- Affected Packages:
- 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.
