The remote Oracle Linux host is missing a security update.
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.
