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.
