Synopsis

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

Description

xorg-x11-server was updated to fix the following security issue :

- Fixed a security issue in which 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)

A non-security issues was also fixed :

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

Solution

Apply SAT patch number 8463 / 8464 as appropriate.
