What is CVE-2014-8091?

The X.Org X Window System, including the X.Org Server versions prior to 1.16.3, contains a flaw related to memory allocation. When employing SUN-DES-1 (Secure RPC) authentication credentials, the system fails to properly check the return value of a malloc operation. This oversight allows remote attackers to exploit the authentication mechanism by sending specially crafted connection requests, leading to a NULL pointer dereference, ultimately resulting in a denial of service condition where the server will crash.
