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.

Security readout for executives and security teams

CVE-2009-1632 is a remote denial-of-service issue in Ipsec-tools before 0.7.2. An attacker could cause memory consumption in the racoon IPsec component, potentially degrading or stopping VPN/IPsec service. The sources do not indicate code execution or data theft. Exposure is most likely on legacy systems or appliances still running Ipsec-tools/racoon before 0.7.2 for IPsec VPN services. Modern systems may be unaffected if vendor packages replaced, patched, or removed Ipsec-tools. Treat as a legacy VPN availability risk. Prioritize internet-facing or business-critical IPsec endpoints first, especially where outages would affect remote access, site-to-site connectivity, or operational systems. Mitigation focus: Upgrade Ipsec-tools to 0.7.2 or a vendor-patched package where applicable.; Review Ubuntu, Red Hat, Mandriva, Gentoo, SUSE, or device-vendor advisories for supported fixes.; Disable unused racoon/IPsec services on systems that no longer require them..
