Description Jan Lieskovsky 2010-08-24 12:58:37 UTC

A NULL pointer dereference flaw was found in the way Quagga's bgpd daemon
parsed paths of autonomous systems (AS). A configured BGP peer could send
a BGP update AS path request with unknown AS type, which could lead to
denial of service (bgpd daemon crash).
