    CVE-2011-4613

    Published: 5 Feb 2014Last Modified: 10 Apr 2026

    Summary:

    Details: 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.
