Description Jan Lieskovsky 2012-03-13 09:48:01 EDT
An assertion failure was found in the way Quagga's bgpd daemon processed certain BGP OPEN messages. A configured BGP peer could send a BGP OPEN message with specially-crafted value of AS4 capability field, which would cause the master BGP daemon (bgpd) to abort (denial of service).
