Red Hat Security Advisory

 

Synopsis: Moderate: bind security and enhancement update

Advisory ID: RHSA-2013:0550-01

Product: Red Hat Enterprise Linux

Advisory URL: https://rhn.redhat.com/errata/RHSA-2013-0550.html

Issue date: 2013-02-21

CVE Names: CVE-2012-5689

=====================================================================

 

1. Summary:

 

Updated bind packages that fix one security issue and add one enhancement

are now available for Red Hat Enterprise Linux 6.

 

The Red Hat Security Response Team has rated this update as having moderate

security impact. A Common Vulnerability Scoring System (CVSS) base score,

which gives a detailed severity rating, is available from the CVE link in

the References section.

 

2. Relevant releases/architectures:

 

Red Hat Enterprise Linux Desktop (v. 6) - i386, x86_64

Red Hat Enterprise Linux Desktop Optional (v. 6) - i386, x86_64

Red Hat Enterprise Linux Workstation (v. 6) - i386, x86_64

Red Hat Enterprise Linux Workstation Optional (v. 6) - i386, x86_64

 

3. Description:

 

The Berkeley Internet Name Domain (BIND) is an implementation of the

Domain Name System (DNS) protocols. BIND includes a DNS server (named); a

resolver library (routines for applications to use when interfacing with

DNS); and tools for verifying that the DNS server is operating correctly.

DNS64 is used to automatically generate DNS records so IPv6 based clients

can access IPv4 systems through a NAT64 server.

 

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. (BZ#906312)

 

All bind users are advised to upgrade to these updated packages, which

contain patches to correct this issue and add this enhancement. After

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

automatically.

 

4. Solution:

 

Before applying this update, make sure all previously-released errata

relevant to your system have been applied.

 

This update is available via the Red Hat Network. Details on how to

use the Red Hat Network to apply this update are available at

https://access.redhat.com/knowledge/articles/11258

 

5. Bugs fixed (http://bugzilla.redhat.com/):

 

903417 - CVE-2012-5689 bind: denial of service when processing queries and with both DNS64 and RPZ enabled

906312 - bind: Backport Response Rate Limiting (DNS RRL) patch into Red Hat Enterprise Linux 6
