USN-1349-1: X.Org vulnerability

26 January 2012

X could be made to start by a user who lacked appropriate permissions.



  • xorg - X.Org X Window System


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

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 11.10
Ubuntu 11.04
Ubuntu 10.10
Ubuntu 10.04

In general, a standard system update will make all the necessary changes.
