Descriptions

The HVMOP_inject_msi function in Xen 4.2.x, 4.3.x, and 4.4.x does not properly check the return value from the IRQ setup check, which allows local HVM guest administrators to cause a denial of service (NULL pointer dereference and crash) via unspecified vectors.

La función HVMOP_inject_msi en Xen 4.2.x, 4.3.x y 4.4.x no comprueba debidamente el valor de retorno de la comprobación de configuraciones IRQ, lo que permite a administradores locales invitados de HVM causar una denegación de servicio (referencia a puntero nulo y caída) a través de vectores no especificados.

Multiple vulnerabilities have been found in Xen, the worst of which can allow remote attackers to cause a Denial of Service condition. Versions less than 4.4.2-r1 are affected.
