A configured Border Gateway Protocol (BGP) peer could send a Route-Refresh message with specially-crafted Outbound Route Filtering (ORF) record, which would cause the master BGP daemon (bgpd) to crash or, possibly, execute arbitrary code with the privileges of the user running bgpd. Upstream changeset:  http://code.quagga.net/?p=quagga.git;a=commit;h=d64379e8f3c0636df53ed08d5b2f1946cfedd0e3 References:  https://bugzilla.redhat.com/show_bug.cgi?id=626783  http://www.quagga.net/news2.php?y=2010&m=8&d=19#id1282241100 B, DoS (crash) while processing certain BGP update AS path messages 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). Upstream changeset:  http://code.quagga.net/?p=quagga.git;a=commit;h=cddb8112b80fa9867156c637d63e6e79eeac67bb References:  https://bugzilla.redhat.com/show_bug.cgi?id=626795  http://www.quagga.net/news2.php?y=2010&m=8&d=19#id1282241100 Could you allocate CVE ids for these?
