high Nessus Plugin ID 51636

Language:

Synopsis

The remote SuSE 11 host is missing one or more security updates.

Description

The X.Org X11 Server was updated to fix several bugs and 2 security issues :

 - This fix adds a workaround for overlapping stacks and heaps in case of OOM conditions.This workaround is necessary if the kernel is not properly adding guard or gap-pages below the stack. (CVE-2010-2240)

 - The fbComposite function in fbpict.c in the Render extension in the X server in X.Org X11R7.1 allows remote authenticated users to cause a denial of service (memory corruption and daemon crash) or possibly execute arbitrary code via a crafted request, related to an incorrect macro definition. (CVE-2010-1166)

Non-Security Bugs fixed :

 - Fix some shortcomings in the Xdmcp implementation. It used to suppress loopback addresses from the list of potential display addresses to report to xdm, even when talking to xdm through a loopback address. Now only display addresses of the same kind as the xdm connection are reported to xdm.

 - This most notably helps Xvnc servers contacting the local xdm, because they were severely affected by the suppression of

Solution

Apply SAT patch number 2968.
