Freshness: upstream tracker timestamp is available; use API updated time as primary recency signal.
CVE-2016-4049 medium priority: Ubuntu including 1 source packages (quagga), 5 status rows across 5 suites (precise, trusty, upstream, wily, xenial): released 4, ignored 1.
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.
