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
(CVE-2009-1632).
