How to fix?

Upgrade Ubuntu:12.04 xen to version 4.1.6.1-0ubuntu0.12.04.6 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream xen package and not the xen package as distributed by Ubuntu. See How to fix? for Ubuntu:12.04 relevant fixed versions and status.

The compat_iret function in Xen 3.1 through 4.5 iterates the wrong way through a loop, which allows local 32-bit PV guest administrators to cause a denial of service (large loop and system hang) via a hypercall_iret call with EFLAGS.VM set.
