RHEL 4 : mod_auth_kerb (RHSA-2006:0746)
Medium Nessus Plugin ID 23797
SynopsisThe remote Red Hat host is missing a security update.
DescriptionUpdated 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.
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.
SolutionUpdate the affected mod_auth_kerb package.
