========================================================================== Ubuntu Security Notice USN-1349-1 January 26, 2012
xorg vulnerability ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 11.10 - Ubuntu 11.04 - Ubuntu 10.10 - Ubuntu 10.04 LTS
Summary:
X could be made to start by a user who lacked appropriate permissions.
Software Description: - xorg: X.Org X Window System
Details:
It was discovered that the X wrapper incorrectly checked certain console permissions when launched by unprivileged users. An attacker connected remotely could use this flaw to start X, bypassing the console permissions check.
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 11.10: xserver-xorg 1:7.6+7ubuntu7.1
Ubuntu 11.04: xserver-xorg 1:7.6+4ubuntu3.2
Ubuntu 10.10: xserver-xorg 1:7.5+6ubuntu3.1
Ubuntu 10.04 LTS: xserver-xorg 1:7.5+5ubuntu1.1
In general, a standard system update will make all the necessary changes.
