RHEL 3 / 4 : ipsec-tools (RHSA-2005:232)

medium Nessus Plugin ID 17622

Synopsis

The remote Red Hat host is missing a security update.

Description

An updated ipsec-tools package that fixes a bug in parsing of ISAKMP headers is now available.

This update has been rated as having moderate security impact by the Red Hat Security Response Team.

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 CVE-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.

Solution

Update the affected ipsec-tools package.
