Descriptions

The HVMOP_pagetable_dying hypercall in Xen 4.0, 4.1, and 4.2 does not properly check the pagetable state when running on shadow pagetables, which allows a local HVM guest OS to cause a denial of service (hypervisor crash) via unspecified vectors.

La llamada HVMOP_pagetable_dying en Xen v4.0, v4.1, y v4.2 no comprueba correctamente el estado "pagetable" cuando se ejecuta en "shadow pagetables", lo que permite a un sistema operativo HVM de invitado causar una denegación de servicio (caída del hipervisor) a través de vectores no especificados.
