1. Summary:
Updated mod_auth_kerb packages that fix a security flaw and a bug in
multiple realm handling are now available for Red Hat Enterprise Linux 4.
This update has been rated as having low security impact by the Red Hat
Security Response Team.

3. Problem description:
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.
