========================================================================== Ubuntu Security Notice USN-3802-1 October 26, 2018
xorg-server, xorg-server-hwe-16.04 vulnerability ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 18.10 - Ubuntu 18.04 LTS - Ubuntu 16.04 LTS
Summary:
X.Org X server could be made to overwrite files as the administrator.
Software Description: - xorg-server: X.Org X11 server - xorg-server-hwe-16.04: X.Org X11 server
Details:
Narendra Shinde discovered that the X.Org X server incorrectly handled certain command line parameters when running as root with the legacy wrapper. When certain graphics drivers are being used, a local attacker could possibly use this issue to overwrite arbitrary files and escalate privileges.
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 18.10: xserver-xorg-core 2:1.20.1-3ubuntu2.1
Ubuntu 18.04 LTS: xserver-xorg-core 2:1.19.6-1ubuntu4.2
Ubuntu 16.04 LTS: xserver-xorg-core-hwe-16.04 2:1.19.6-1ubuntu4.1~16.04.2
After a standard system update you need to reboot your computer to make all the necessary changes.
