Descriptions

bgpd/bgp_attr.c in Quagga 0.98.6 and earlier, and 0.99.6 and earlier 0.99 versions, does not validate length values in the MP_REACH_NLRI and MP_UNREACH_NLRI attributes, which allows remote attackers to cause a denial of service (daemon crash or exit) via crafted UPDATE messages that trigger an assertion error or out of bounds read.

bgpd/bgp_attr.c en Quagga 0.98.6 y versiones anteriores, y 0.99.6 y versiones 0.99 anteriores, no validan la longitud de los valores en los atributos MP_REACH_NLRI y MP_UNREACH_NLRI, lo cual permite a atacantes remotos provocar una denegación de servicio (caída o finalización de demonio) mediante mensajes UPDATE manipulados que disparan un error de aserción o lectura fuera de límites.
