CVE-2011-4029

Publication date 18 October 2011

Last updated 24 July 2024

Ubuntu priority

High

Why this priority?

The LockServer function in os/utils.c in X.Org xserver before 1.11.2 allows local users to change the permissions of arbitrary files to 444, read those files, and possibly cause a denial of service (removed execution permission) via a symlink attack on a temporary lock file.
