TITLE:
Red Hat update for xen

SECUNIA ADVISORY ID:
SA36908

VERIFY ADVISORY:
http://secunia.com/advisories/36908/

DESCRIPTION:
Red Hat has issued an update for xen. This fixes a weakness, which
can be exploited by malicious people to bypass certain security
restrictions.

The weakness is caused due to PyGrub not properly honoring the
"password" configuration option for para-virtualised guests, which
e.g. allows to edit the guest's kernel boot parameters.

Successful exploitation requires access to the guest's console.

SOLUTION:
Updated packages are available via Red Hat Network.
http://rhn.redhat.com

PROVIDED AND/OR DISCOVERED BY:
Reported via the Red Hat Issue Tracker.

ORIGINAL ADVISORY:
