Updated xen packages that fix one security issue are now available for

The xen packages contain administration tools and the xend service for
managing the kernel-xen kernel for virtualization on Red Hat
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)
Red Hat would like to thank Xinli Niu for reporting this issue.
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.
