Synopsis :

The remote FreeBSD host is missing a security-related update.

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.
