Description
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.
Faiblesses (CWE)
- CWE-228 — Improper Handling of Syntactically Invalid Structure
- CWE-835 — Boucle dont la condition de sortie est inatteignable (boucle infinie)
