Description Jan Lieskovsky 2012-03-13 13:48:01 UTC
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). Upstream patch:  http://git.savannah.gnu.org/cgit/quagga.git/commit/?id=5861739f8c38bc36ea9955e5cb2be2bf2f482d70
