RHEL 4 : mod_auth_kerb (RHSA-2006:0746)

high Nessus Plugin ID 23797

Synopsis

The remote Red Hat host is missing a security update for mod_auth_kerb.

Description

The remote Redhat Enterprise Linux 4 host has a package installed that is affected by a vulnerability as referenced in the RHSA-2006:0746 advisory.

mod_auth_kerb is module for the Apache HTTP Server designed to provide Kerberos authentication over HTTP.

An off by one flaw was found in the way mod_auth_kerb handles certain Kerberos authentication messages. A remote client could send a specially crafted authentication request which could crash an httpd child process (CVE-2006-5989).

A bug in the handling of multiple realms configured using the KrbAuthRealms directive has also been fixed.

All users of mod_auth_kerb should upgrade to these updated packages, which contain backported patches that resolve 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 mod_auth_kerb package based on the guidance in RHSA-2006:0746.
