Oracle Linux 5 : pam_krb5 (ELSA-2008-0907)

This script is Copyright (C) 2013-2016 Tenable Network Security, Inc.

Synopsis :

The remote Oracle Linux host is missing a security update.

Description :

From Red Hat Security Advisory 2008:0907 :

An updated pam_krb5 package that fixes a security issue is now
available for Red Hat Enterprise Linux 5.

This update has been rated as having moderate security impact by the
Red Hat Security Response Team.

The pam_krb5 module allows Pluggable Authentication Modules (PAM)
aware applications to use Kerberos to verify user identities by
obtaining user credentials at log in time.

A flaw was found in the pam_krb5 'existing_ticket' configuration
option. If a system is configured to use an existing credential cache
via the 'existing_ticket' option, it may be possible for a local user
to gain elevated privileges by using a different, local user's
credential cache. (CVE-2008-3825)

Red Hat would like to thank Stephane Bertin for responsibly
disclosing this issue.

Users of pam_krb5 should upgrade to this updated package, which
contains a backported patch to resolve this issue.
