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

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

Synopsis :

The remote Scientific Linux host is missing one or more security

Description :

A memory leak flaw was found in the krb5_unparse_name() function of
the MIT Kerberos kadmind service. An authenticated attacker could
repeatedly send specially crafted requests to the server, which could
cause the server to consume large amounts of memory resources,
ultimately leading to a denial of service due to memory exhaustion.

An out-of-bounds read flaw was found in the kadmind service of MIT
Kerberos. An authenticated attacker could send a maliciously crafted
message to force kadmind to read beyond the end of allocated memory,
and write the memory contents to the KDC database if the attacker has
write permission, leading to information disclosure. (CVE-2015-8629)

After installing the updated packages, running Kerberos services
(krb5kdc, kadmin, and kprop) will be restarted automatically.
