Описание
Реализация Internet Key Exchange version 1 (IKEv1) (isakmp_agg.c) в racoon в ipsec-tools при запуске в режиме aggressive, позволяет злоумышленникам, действующим удаленно, вызвать отказ в обслуживании (разыменование нулевого указателя и аварийное завершение работы), используя специально сформированные IKE-пакеты, как показано на примере PROTOS ISAKMP Test Suite для IKEv1.
