openSUSE Security Update : xorg-x11-server (openSUSE-SU-2013:1610-1)

This script is Copyright (C) 2014-2016 Tenable Network Security, Inc.


Synopsis :

The remote openSUSE host is missing a security update.

Description :

Fixes the following security issue :

- an authenticated X client can cause an X server to use
memory after it was freed, potentially leading to crash
and/or memory corruption. (CVE-2013-4396, bnc#843652)
and the following bug was fixed too :

- rfbAuthReenable is accessing rfbClient structure that
was in most cases already freed. It actually needs only
ScreenPtr, so pass it directly. (bnc#816813)
