This issue did not affect Red Hat Enterprise Linux 6 and Red Hat Enterprise MRG 2.
The risks associated with fixing this bug are greater than its security impact. This issue is not currently planned to be addressed in future kernel-xen updates for Red Hat Enterprise Linux 5. Using fully virtualized (HVM) guests, or PV guests with trusted kernel/administrator avoids this issue.
