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

Medium Nessus Plugin ID 60437

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.

Solution

Update the affected packages.
