Severity
Summary
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.
