Mandriva Linux Security Advisory - An input validation flaw was found in X.org's MIT-SHM extension. A client connected to the X.org server could read arbitrary server memory, resulting in the disclosure of sensitive data of other users of the X.org server. Multiple integer overflows were found in X.org's Render extension. A malicious authorized client could exploit these issues to cause a denial of service (crash) or possibly execute arbitrary code with root privileges on the X.org server. The Metisse program is likewise affected by these issues; the updated packages have been patched to prevent them.
