Descriptions

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."

Xen 4.2.x y 4.3.x, cuando la virtualización anidada es desactivada, no comprueba correctamente las rutas de emulación para VMLAUNCH y (2) VMRESUME, lo que permite a usuarios HVM locales provocar una denegación de servicio (cierre del host) a través de vectores sin especificar, relacionados con "ejecución de instrucción VMX en invitado".
