USN-571-2: X.org regression

USN-571-1 fixed vulnerabilities in X.org. The upstream fixes were incomplete, and under certain situations, applications using the MIT-SHM extension e.g. Java, wxWidgets would crash with BadAlloc X errors. This update fixes the problem. We apologize for the inconvenience. Original advisory detail...
