====================================================================                   Red Hat Security Advisory

Synopsis:          Important: bind97 security update
Advisory ID:       RHSA-2012:1364-01
Product:           Red Hat Enterprise Linux
Advisory URL:      https://access.redhat.com/errata/RHSA-2012:1364.html
Issue date:        2012-10-12
CVE Names:         CVE-2012-5166 
====================================================================
1. Summary:

Updated bind97 packages that fix one security issue are now available for
Red Hat Enterprise Linux 5.

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

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 certain combinations of resource
records. A remote attacker could use this flaw to cause a recursive
resolver, or an authoritative server in certain configurations, to lockup.
(CVE-2012-5166)

Users of bind97 are advised to upgrade to these updated packages, which
correct this issue. 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
