Xen 4.5.3, 4.6.3, and 4.7.x allow local HVM guest OS administrators to overwrite hypervisor memory and consequently gain host OS privileges by leveraging mishandling of instruction pointer truncation during emulation.
Xen 4.5.3, 4.6.3 y 4.7.x permiten a administradores locales del SO invitado HVM sobreescribir memoria del hipervisor y consecuentemente obtener privilegios del SO anfitrión aprovechando el mal manejo del truncamiento del puntero de instrucción durante la emulación.
