Descriptions

Xen, possibly before 4.0.2, allows local 64-bit PV guests to cause a denial of service (host crash) by specifying user mode execution without user-mode pagetables.

Xen, probablemente anterior a v4.0.2 permite a invitados locales de 64-bit PV provocar una denegación de servicio (caída del host) especificando la ejecución en modo usuario sin las tablas de página.
