Red Hat Security Advisory

 

Synopsis: Important: bind97 security update

Advisory ID: RHSA-2012:0717-01

Product: Red Hat Enterprise Linux

Advisory URL: https://rhn.redhat.com/errata/RHSA-2012-0717.html

Issue date: 2012-06-07

CVE Names: CVE-2012-1033 CVE-2012-1667

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

 

1. Summary:

 

Updated bind97 packages that fix two security issues are now available for

Red Hat Enterprise Linux 5.

 

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

important security impact. Common Vulnerability Scoring System (CVSS) base

scores, which give detailed severity ratings, are available for each

vulnerability from the CVE links in the References section.

 

2. Relevant releases/architectures:

 

RHEL Desktop Workstation (v. 5 client) - i386, x86_64

Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, 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.

 

A flaw was found in the way BIND handled zero length resource data records.

A malicious owner of a DNS domain could use this flaw to create

specially-crafted DNS resource records that would cause a recursive

resolver or secondary server to crash or, possibly, disclose portions of

its memory. (CVE-2012-1667)

 

A flaw was found in the way BIND handled the up[censored] of cached name server

(NS) resource records. A malicious owner of a DNS domain could use this

flaw to keep the domain resolvable by the BIND server even after the

delegation was removed from the parent DNS zone. With this update, BIND

limits the time-to-live of the replacement record to that of the

time-to-live of the record being replaced. (CVE-2012-1033)

 

Users of bind97 are advised to upgrade to these updated packages, which

correct these issues. 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/):

 

788650 - CVE-2012-1033 bind: deleted domain name resolving flaw

828078 - CVE-2012-1667 bind: handling of zero length rdata can cause named to terminate unexpectedly
