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

high Nessus Plugin ID 17622

Synopsis

The remote Red Hat host is missing a security update for ipsec-tools.

Description

The remote Redhat Enterprise Linux 4 host has a package installed that is affected by a vulnerability as referenced in the RHSA-2005:232 advisory.

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.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL ipsec-tools package based on the guidance in RHSA-2005:232.
