CVE-2011-4613 Information

Description

The X.Org X wrapper (xserver-wrapper.c) in Debian GNU/Linux and Ubuntu Linux does not properly verify the TTY of a user who is starting X which allows local users to bypass intended access restrictions by associating stdin with a file that is misinterpreted as the console TTY.
