NVD Description

Note: Versions mentioned in the description apply only to the upstream quagga-contrib package and not the quagga-contrib package as distributed by Oracle. See How to fix? for Oracle:6 relevant fixed versions and status.

The bgp_dump_routes_func function in bgpd/bgp_dump.c in Quagga does not perform size checks when dumping data, which might allow remote attackers to cause a denial of service (assertion failure and daemon crash) via a large BGP packet.
