Ipsec-Tools: >> Ipsec-Tools >> 0.3.2 Security Vulnerabilities
Multiple memory leaks in Ipsec-tools before 0.7.2 allow remote attackers to cause a denial of service (memory consumption) via vectors involving (1) signature verification during user authentication with X.509 certificates, related to the eay_check_x509sign function in src/racoon/crypto_openssl.c; and (2) the NAT-Traversal (aka NAT-T) keepalive implementation, related to src/racoon/nattraversal.c.

racoon/isakmp_frag.c in ipsec-tools before 0.7.2 allows remote attackers to cause a denial of service (crash) via crafted fragmented packets without a payload, which triggers a NULL pointer dereference.

The eay_check_x509cert function in KAME Racoon successfully verifies certificates even when OpenSSL validation fails, which could allow remote attackers to bypass authentication.
