How to fix?

Upgrade Debian:9 quagga to version 0.99.20.1-1 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.

Buffer overflow in the ospf_ls_upd_list_lsa function in ospf_packet.c in the OSPFv2 implementation in ospfd in Quagga before 0.99.20.1 allows remote attackers to cause a denial of service (assertion failure and daemon exit) via a Link State Update (aka LS Update) packet that is smaller than the length specified in its header.
