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

This script is Copyright (C) 2013-2014 Tenable Network Security, Inc.


Synopsis :

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

Description :

A flaw was found in the DNS64 implementation in BIND when using
Response Policy Zones (RPZ). If a remote attacker sent a specially
crafted query to a named server that is using RPZ rewrite rules, named
could exit unexpectedly with an assertion failure. Note that DNS64
support is not enabled by default. (CVE-2012-5689)

This update also adds the following enhancement :

- Previously, it was impossible to configure the the
maximum number of responses sent per second to one
client. This allowed remote attackers to conduct traffic
amplification attacks using DNS queries with spoofed
source IP addresses. With this update, it is possible to
use the new 'rate-limit' configuration option in
named.conf and configure the maximum number of queries
which the server responds to. Refer to the BIND
documentation for more details about the 'rate-limit'
option.

After installing the update, the BIND daemon (named) will be restarted
automatically.
