Description Petr Matousek 2013-01-07 08:56:19 EST 
A change to an internal interface within the hypervisor invalidated an
ASSERT in a caller of that API. This code path is exposed to PV guests
via a hypercall allowing administrators of PV guests to crash the
hypervisor if it is built with debugging enabled.

Malicious administrators of PV guests running on hypervisors built
with the non-default debug=y option can crash the host.

Comment 2 Petr Matousek 2013-01-07 08:57:21 EST 
Statement:

Not vulnerable.

This issue did not affect the versions of the kernel-xen package as shipped with Red Hat Enterprise Linux 5.

This issue did not affect Red Hat Enterprise Linux 6 and Red Hat Enterprise MRG as we did not have support for Xen hypervisor.
