Name of the Vulnerable Software and Affected Versions Xen versions 4.1 through 4.2 Citrix XenServer version 6.0.2 and earlier

Description The issue allows local HVM guest OS kernels to cause a denial of service (host crash) and possibly read hypervisor or guest memory. This is due to a missing range check of map->index in the PHYSDEVOP map pirq function.

Recommendations For Xen versions 4.1 through 4.2, consider applying a patch that includes a range check for map->index in the PHYSDEVOP map pirq function to prevent the denial of service and potential memory read. For Citrix XenServer version 6.0.2 and earlier, update to a version that includes the fix for the PHYSDEVOP map pirq function.
