Mandriva Linux Security Advisory MDVSA-2009:114
http://www.mandriva.com/security/
_______________________________________________________________________

Package : ipsec-tools
Date : May 18, 2009
Affected: Corporate 4.0, Multi Network Firewall 2.0
_______________________________________________________________________

Problem Description:

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).

The updated packages have been patched to prevent this.
