3. Problem 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.

4. Solution:

Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.  Use Red Hat
Network to download and update your packages.  To launch the Red Hat
Update Agent, use the following command:

    up2date
