Scientific Linux Security Update : xen on SL5.x i386/x86_64

This script is Copyright (C) 2012 Tenable Network Security, Inc.


Synopsis :

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

Description :

The xen packages contain administration tools and the xend service for
managing the kernel-xen kernel for virtualization on Scientific Linux.

A flaw was found in the way the pyGrub boot loader handled compressed
kernel images. A privileged guest user in a para-virtualized guest (a
DomU) could use this flaw to create a crafted kernel image that, when
attempting to boot it, could result in an out-of-memory condition in
the privileged domain (the Dom0). (CVE-2012-2625)

All users of xen are advised to upgrade to these updated packages,
which contain a backported patch to correct this issue. After
installing the updated packages, the xend service must be restarted
for this update to take effect.
