Description Petr Matousek 2012-09-06 15:18:57 EDT
A guest administrator who is granted access to the graphical console
of a Xen guest can access the qemu monitor.  The monitor can be used
to access host resources.

A malicious guest administrator can access host resources (perhaps
belonging to other guests or the underlying system) and may be able to
escalate their privilege to that of the host.

Comment 2 Petr Matousek 2012-09-06 15:20:58 EDT
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.
