Scientific Linux Security Update : xorg-x11-drv-qxl on SL6.x i386/x86_64

This script is Copyright (C) 2013 Tenable Network Security, Inc.


Synopsis :

The remote Scientific Linux host is missing one or more security
updates.

Description :

A flaw was found in the way the host's qemu-kvm qxl driver and the
guest's X.Org qxl driver interacted when a SPICE connection
terminated. A user able to initiate a SPICE connection to a guest
could use this flaw to make the guest temporarily unavailable or,
potentially (if the sysctl kernel.softlockup_panic variable was set to
'1' in the guest), crash the guest. (CVE-2013-0241)

All running X.Org server instances using the qxl driver must be
restarted for this update to take effect.
