Topic

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.

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.
