RHSA-2005-232: ipsec

Vulnerability Assessment Summary
Check for the version of the ipsec packages

Detailed Explanation for this Vulnerability Assessment

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 a possible hacker 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 existence 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.
