CVE-2011-4028

Publication date 18 October 2011

Ubuntu priority

Medium

Why this priority?

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.
