Fedora Core 2 : ipsec-tools-0.2.5-2 (2004-132)
Medium Nessus Plugin ID 13707
SynopsisThe remote Fedora Core host is missing a security update.
DescriptionAn updated ipsec-tools package that fixes vulnerabilities in racoon (the ISAKMP daemon) is now available.
When ipsec-tools receives an ISAKMP header, it will attempt to allocate sufficient memory for the entire ISAKMP message according to the header's length field. If an attacker crafts an ISAKMP header with a extremely large value in the length field, racoon may exceed operating system resource limits and be terminated, resulting in a denial of service. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2004-0403 to this issue.
Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
SolutionUpdate the affected ipsec-tools and / or ipsec-tools-debuginfo packages.
