Scientific Linux Security Update : krb5 on SL6.x i386/x86_64

This script is Copyright (C) 2012-2014 Tenable Network Security, Inc.

Synopsis :

The remote Scientific Linux host is missing one or more security

Description :

Kerberos is a network authentication system which allows clients and
servers to authenticate to each other using symmetric encryption and a
trusted third party, the Key Distribution Center (KDC).

An uninitialized pointer use flaw was found in the way the MIT
Kerberos KDC handled initial authentication requests (AS-REQ). A
remote, unauthenticated attacker could use this flaw to crash the KDC
via a specially crafted AS-REQ request. (CVE-2012-1015)

A NULL pointer dereference flaw was found in the MIT Kerberos
administration daemon, kadmind. A Kerberos administrator who has the
'create' privilege could use this flaw to crash kadmind.

All krb5 users should upgrade to these updated packages, which contain
backported patches to correct these issues. After installing the
updated packages, the krb5kdc and kadmind daemons will be restarted
