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
updates.

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).

Multiple NULL pointer dereference and assertion failure flaws were
found in the MIT Kerberos KDC when it was configured to use an LDAP
(Lightweight Directory Access Protocol) or Berkeley Database (Berkeley
DB) back end. A remote attacker could use these flaws to crash the
KDC. (CVE-2011-1527, CVE-2011-1528, CVE-2011-1529)

All krb5 users should upgrade to these updated packages, which contain
a backported patch to correct these issues. After installing the
updated packages, the krb5kdc daemon will be restarted automatically.
