The eaycheckx509cert function in KAME Racoon successfully verifies certificates even when OpenSSL validation fails, which could allow remote attackers to bypass authentication.

The KAME IKE Daemon Racoon, when authenticating a peer during Phase 1, validates the X.509 certificate but does not verify the RSA signature authentication, which allows remote attackers to establish unauthorized IP connections or conduct man-in-the-middle attacks using a valid, trusted X.509 certificate.

The KAME racoon daemon in ipsec-tools before 0.5 allows remote attackers to cause a denial of service (crash) via malformed ISAKMP packets.

racoon before 20040407b allows remote attackers to cause a denial of service (infinite loop and dropped connections) via an IKE message with a malformed Generic Payload Header containing invalid (1) "Security Association Next Payload" and (2) "RESERVED" fields.

KAME IKE daemon (racoon) does not properly handle hash values, which allows remote attackers to delete certificates via (1) a certain delete message that is not properly handled in isakmp.c or isakmpinf.c, or (2) a certain INITIAL-CONTACT message that is not properly handled in isakmpinf.c.

Racoon before 20040408a allows remote attackers to cause a denial of service (memory consumption) via an ISAKMP packet with a large length field.
