Scientific Linux Security Update : xen on SL5.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 libxc, the Xen control library, handled
excessively large kernel and ramdisk images when starting new guests.
A privileged guest user in a para-virtualized guest (a DomU) could
create a crafted kernel or ramdisk image that, when attempting to use
it during guest start, could result in an out-of-memory condition in
the privileged domain (the Dom0). (CVE-2012-4544)

After installing the updated packages, the xend service must be
restarted for this update to take effect.
