CVE-2016-4049
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.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (4.64%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
