05 Jul 2017 — Xen through 4.8.x does not validate memory allocations during certain P2M operations, which allows guest OS users to obtain privileged host OS access, aka XSA-222. Xen, hasta las versiones 4.8.x, no valida las asignaciones de memoria durante ciertas operaciones de P2M, lo que permite que los usuarios invitados del sistema operativo obtengan acceso privilegiado al sistema operativo. Esto también se conoce como XSA-222.
