It was discovered that ipsec-tools did not properly handle memory
usage when verifying certificate signatures or processing
nat-traversal keep-alive messages. A remote attacker could send
specially crafted packets to the server and exhaust available memory,
leading to a denial of service. (CVE-2009-1632).
