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).

A NULL pointer dereference flaw was found in the way the MIT Kerberos
KDC processed certain TGS (Ticket-granting Server) requests. A remote,
authenticated attacker could use this flaw to crash the KDC via a
specially-crafted TGS request. (CVE-2011-1530)

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