CVE-2005-2456

Array index overflow in the xfrm_sk_policy_insert function in xfrm_user.c in Linux kernel 2.6 allows local users to cause a denial of service (oops or deadlock) and possibly execute arbitrary code via a p->dir value that is larger than XFRM_POLICY_OUT, which is used as an index in the sock->sk_policy array.

Desbordamiento en el índice del array en la función xfrm_sk_policy_insert en xfrm_user.c en el kernel de Linux 2.6 permite que usuarios locales provoquen una denegación de servicio y posiblemente ejeucten código arbitrario mediante una valor de p->dir que sea mayor que XFRM_POLICY_OUT (usado como índice en el array sock->sk_policy).
