Synopsis:          Moderate: xen security update
Issue Date:        2013-02-07
CVE Numbers:       CVE-2012-4544
--

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.
