Scientific Linux Security Update : bind on SL 3.0.x , SL 4.x, SL 5.x

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


Synopsis :

The remote Scientific Linux host is missing one or more security
updates.

Description :

The DNS protocol protects against spoofing attacks by requiring an
attacker to predict both the DNS transaction ID and UDP source port of
a request. In recent years, a number of papers have found problems
with DNS implementations which make it easier for an attacker to
perform DNS cache-poisoning attacks.

Previous versions of BIND did not use randomized UDP source ports. If
an attacker was able to predict the random DNS transaction ID, this
could make DNS cache-poisoning attacks easier. In order to provide
more resilience, BIND has been updated to use a range of random UDP
source ports. (CVE-2008-1447)

Note: This errata also updates SELinux policy to allow BIND to use
random UDP source ports.
