How to fix?

Upgrade Debian:9 quagga to version 0.99.9-1 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.

bgpd in Quagga before 0.99.9 allows explicitly configured BGP peers to cause a denial of service (crash) via a malformed (1) OPEN message or (2) a COMMUNITY attribute, which triggers a NULL pointer dereference. NOTE: vector 2 only exists when debugging is enabled.
