A denial of service flaw was found in the way Quagga's ospf6d daemon performed routes removal. In certain circumstances when removing the route the ospf6d daemon terminated with assertion failure when trying to determine / find, which route to remove. An OSPF6 router could use this flaw to cause ospf6d on an adjacent router to abort.
