How to fix?

Upgrade Debian:unstable gobgp to version 4.4.0-1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream gobgp package and not the gobgp package as distributed by Debian. See How to fix? for Debian:unstable relevant fixed versions and status.

An integer underflow in the BGPUpdate.DecodeFromBytes function (/bgp/bgp.go) of gobgp v4.3.0 allows attackers to cause a Denial of Service (DoS) via supplying a crafted BGP UPDATE message.
