CVE-2016-4049 (opens in a new tab)How to fix?
Upgrade Oracle:6 quagga to version 0:0.99.15-14.el6 or higher.
This issue was patched in ELSA-2017-0794.
NVD Description
Note: Versions mentioned in the description apply only to the upstream quagga package and not the quagga 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.
