Package: xen-hypervisor-3.2-1-i386
Version: 3.2-1
Severity: critical
Tags: security
Justification: DoS of entire system regardless of privilege
When running the exploit listed in bug 464953 [1], Xen's memory state
becomes corrupted and the hypervisor eventually crashes, taking all of
the domU's with it. As such, this breaks operational behaviour, so I have
marked this as critical.

The submitter was not able to show evidence that this is a real bug.
Also none of my tests with a x86_32 Xen produced a crash within the
hypervisor.
