Scientific Linux Security Update : xen on SL5.x i386/x86_64 (20120731)

low Nessus Plugin ID 61408

Language:

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.

Solution

Update the affected packages.
