low Nessus Plugin ID 64499

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.

Solution

Update the affected packages.
