Description

Quagga contains a flaw that may allow an unauthenticated attacker to inject RIP routes into the 'RIPd' service. The issue is triggered when the service is configured with MD5 authentication but no specific RIP version in the configuration file. It is then possible to send unauthenticated RIPv1 'RESPONSE' packets that will be accepted by the service, causing a manipulation of the RIP routing table and resulting in a loss of integrity.
