How to fix?

Upgrade Debian:9 quagga to version 0.99.22.4-1 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.

Stack-based buffer overflow in the new_msg_lsa_change_notify function in the OSPFD API (ospf_api.c) in Quagga before 0.99.22.2, when --enable-opaque-lsa and the -a command line option are used, allows remote attackers to cause a denial of service (crash) via a large LSA.
