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.

RIPd in Quagga 0.98 and 0.99 before 20060503 does not properly enforce RIPv2 authentication requirements, which allows remote attackers to modify routing state via RIPv1 RESPONSE packets.
