The Red Hat security team reported two vulnerabilities:
A stack buffer overflow flaw was found in the way Quagga's bgpd daemon processed Route-Refresh messages. 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.
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).
