CVE-2017-13715

The __skb_flow_dissect function in net/core/flow_dissector.c in the Linux kernel before 4.3 does not ensure that n_proto, ip_proto, and thoff are initialized, which allows remote attackers to cause a denial of service (system crash) or possibly execute arbitrary code via a single crafted MPLS packet.

función __skb_flow_dissect en net/core/flow_dissector.c en el kernel Linux en versiones anteriores a la 4.3 no garantiza que se inicialicen n_proto, ip_proto y thoff. Esto permite que atacantes remotos provoquen una denegación de servicio (bloqueo del sistema) o que ejecuten código arbitrario mediante un único paquete MPLS manipulado.
