Description

Matthieu Herrb of X.Org reports :

Several vulnerabilities have been found in the server-side code of some extensions in the X Window System. Improper validation of client-provided data can cause data corruption.

Exploiting these overflows will crash the X server or, under certain circumstances allow the execution of arbitrary machine code.

When the X server is running with root privileges (which is the case for the Xorg server and for most kdrive based servers), these vulnerabilities can thus also be used to raise privileges.

All these vulnerabilities, to be exploited successfully, require either an already established connection to a running X server (and normally running X servers are only accepting authenticated connections), or a shell access with a valid user on the machine where the vulnerable server is installed.
