Descriptions

The IRQ setup in Xen 4.2.x and 4.3.x, when using device passthrough and configured to support a large number of CPUs, frees certain memory that may still be intended for use, which allows local guest administrators to cause a denial of service (memory corruption and hypervisor crash) and possibly execute arbitrary code via vectors related to an out-of-memory error that triggers a (1) use-after-free or (2) double free.

La configuración de IRQ en Xen 4.2.x y 4.3.x, utilizando passthrough de dispositivos y configurado para soportar un gran número de CPUs, libera cierta memoria que todavía puedan destinarse a su utilización, lo que permite a los administradores de los huéspedes locales provocar una denegación de servicio (corrupción de memoria y caída de hipervisor) y posiblemente ejecutar código arbitrario a través de vectores relacionados con un error de falta de memoria que provoca un fallo de (1) uso después de liberación o (2) doble liberación de memoria.
