Descriptions

The do_physdev_op function in Xen 4.1.5, 4.1.6.1, 4.2.2 through 4.2.3, and 4.3.x does not properly restrict access to the (1) PHYSDEVOP_prepare_msix and (2) PHYSDEVOP_release_msix operations, which allows local PV guests to cause a denial of service (host or guest malfunction) or possibly gain privileges via unspecified vectors.

La función do_physdev_op en Xen 4.1.5, 4.1.6.1, 4.2.2 hasta 4.2.3 y 4.3.x no restringe adecuadamente el acceso a las operaciones: (1) PHYSDEVOP_release_msix y (2) PHYSDEVOP_prepare_msix , lo que permite a los huéspedes PV locales provocar una denegación de servicio ( mal funcionamiento de host o invitado) o posiblemente obtener privilegios a través de vectores no especificados.

Multiple vulnerabilities have been found in Xen, the worst of which could lead to arbitrary code execution. Versions less than 4.3.2-r4 are affected.
