The do_hvm_op function in xen/arch/x86/hvm/hvm.c in Xen 4.2.x on the x86_32
platform does not prevent HVM_PARAM_NESTEDHVM (aka nested virtualization)
operations, which allows guest OS users to cause a denial of service
(long-duration page mappings and host OS crash) by leveraging
administrative access to an HVM guest in a domain with a large number of
VCPUs.
