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)

Solution

Update the affected xorg-x11-server packages.
