Descriptions

The ospf6_lsa_is_changed function in ospf6_lsa.c in the OSPFv3 implementation in ospf6d in Quagga before 0.99.19 allows remote attackers to cause a denial of service (assertion failure and daemon exit) via trailing zero values in the Link State Advertisement (LSA) header list of an IPv6 Database Description message.

La función ospf6_lsa_is_changed en ospf6_lsa.c en la ejecución de OSPFv3 en ospf6d en Quagga anteriores a v0.99.19 permite a atacantes remotos causar una denegación de servicio (error de aserción y caída del demonio) a través de la inclusión de valores cero en la cabecera de la lista del Link State Advertisement (LSA) de una descripción de mensaje de base de datos.
