| Description: | The ipsec-tools package is used in conjunction with the IPsec functionality in the linux kernel. The ipsec-tools package includes:
- setkey, a program to directly manipulate policies and SAs - racoon, an IKEv1 keying daemon
A bug was found in the way the racoon daemon handled incoming ISAKMP requests. It is possible that an attacker could crash the racoon daemon by sending a specially crafted ISAKMP packet. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2005-0398 to this issue.
Additionally, the following issues have been fixed: - racoon mishandled restarts in the presence of stale administration sockets. - on Red Hat Enterprise Linux 4, racoon and setkey did not properly set up forward policies, which prevented tunnels from working.
Users of ipsec-tools should upgrade to this updated package, which contains backported patches, and is not vulnerable to these issues.
