Descriptions
The Quagga BGP daemon (bgpd) prior to version 1.2.3 has a bug in its parsing of "Capabilities" in BGP OPEN messages, in the bgp_packet.c:bgp_capability_msg_parse function. The parser can enter an infinite loop on invalid capabilities if a Multi-Protocol capability does not have a recognized AFI/SAFI, causing a denial of service.
El demonio Quagga BGP (bgpd), en versiones anteriores a la 1.2.3, tiene un error en su análisis de "Capabilities" en los mensajes BGP OPEN, en la función bgp_packet.c:bgp_capability_msg_parse. El analizador puede entrar en un bucle infinito o invalidar capacidades si una capacidad Multi-Protocol no tiene un AFI/SAFI reconocido, lo que provocaría una denegación de servicio (DoS).
