Details

Julien Bernard discovered that libndp incorrectly performed origin checks
when receiving Neighbor Discovery Protocol (NDP) messages. A remote
attacker outside of the local network could use this issue to advertise a
node as a router, causing a denial of service, or possibly to act as a
machine-in-the-middle.
