Xen 4.2.x and 4.3.x, when nested virtualization is disabled, does not properly check the emulation paths for (1) VMLAUNCH and (2) VMRESUME, which allows local HVM guest users to cause a denial of service (host crash) via unspecified vectors related to "guest VMX instruction execution."

CVE-2013-4551 xen: Host crash due to guest VMX instruction execution
Permission checks on the emulation paths (intended for guests using
nested virtualization) for VMLAUNCH and VMRESUME were deferred too
much. The hypervisor would try to use internal state which is not set
up unless nested virtualization is actually enabled for a guest.
A malicious or misbehaved HVM guest, including malicious or misbehaved user
mode code run in the guest, might be able to crash the host.
Xen 4.2.x and later are vulnerable.
Xen 4.1.x and earlier are not vulnerable.
Only HVM guests run on VMX capable (e.g. Intel) hardware can take
advantage of this vulnerability.
Running only PV guests, or running HVM guests on SVM capable
(e.g. AMD) hardware will avoid this issue.
