CWE-20  (opens in a new tab)

How to fix?

Upgrade Debian:9 quagga to version 1.0.20160315-2 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream quagga package and not the quagga package as distributed by Debian. See How to fix? for Debian:9 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.
