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.

The ospf6_lsa_is_changed function in ospf6_lsa.c in the OSPFv3 implementation in ospf6d in Quagga before 0.99.19 allows remote attackers to cause a denial of service (assertion failure and daemon exit) via trailing zero values in the Link State Advertisement (LSA) header list of an IPv6 Database Description message.
