Impact
Remote unauthenticated attackers can crash the routing protocol daemon (rpd), causing a complete routing denial of service. The attack requires network access to a device using EVPN multihoming with preference-based designated-forwarder election.
Root cause
An infinite loop condition in rpd is triggered when processing EVPN multihoming routes with preference-based designated-forwarder election.
