Descriptions

The xfrm_state_netlink function in net/xfrm/xfrm_user.c in the Linux kernel before 3.5.7 does not properly handle error conditions in dump_one_state function calls, which allows local users to gain privileges or cause a denial of service (NULL pointer dereference and system crash) by leveraging the CAP_NET_ADMIN capability.

La función xfrm_state_netlink en net/xfrm/xfrm_user.c en el kernel de Linux anterior a v3.5.7 no controla correctamente las condiciones de error en las llamadas a funciones dump_one_state, permitiendo a usuarios locales obtener privilegios o causar una denegación de servicio (referencia a puntero NULL y caída del sistema ) mediante el aprovechamiento de la capacidad CAP_NET_ADMIN.
