NVD Description

Note: Versions mentioned in the description apply only to the upstream xorg-x11-server-source package and not the xorg-x11-server-source package as distributed by Centos. See How to fix? for Centos:6 relevant fixed versions and status.

The LockServer function in os/utils.c in X.Org xserver before 1.11.2 allows local users to determine the existence of arbitrary files via a symlink attack on a temporary lock file, which is handled differently if the file exists.
