How to fix?

Upgrade Debian:9 quagga to version 0.99.19-1 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.

Heap-based buffer overflow in the ecommunity_ecom2str function in bgp_ecommunity.c in bgpd in Quagga before 0.99.19 allows remote attackers to cause a denial of service (daemon crash) or possibly execute arbitrary code by sending a crafted BGP UPDATE message over IPv4.
