CVE-2011-4029

Status Candidate

Overview

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.

Red Hat Security Advisory 2012-0939-04
Posted Jun 20, 2012
Authored by Red Hat | Site access.redhat.com

Red Hat Security Advisory 2012-0939-04 - X.Org is an open source implementation of the X Window System. It provides the basic low-level functionality that full-fledged graphical user interfaces are designed upon. A flaw was found in the way the X.Org server handled lock files. A local user with access to the system console could use this flaw to determine the existence of a file in a directory not accessible to the user, via a symbolic link attack. A race condition was found in the way the X.Org server managed temporary lock files. A local attacker could use this flaw to perform a symbolic link attack, allowing them to make an arbitrary file world readable, leading to the disclosure of sensitive information.
