"Updated bind packages that fix one security issue and one bug are now
available for Red Hat Enterprise Linux 6.

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.

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 denial of service flaw was found in the libdns library. A remote
attacker could use this flaw to send a specially crafted DNS query to
named that, when processed, would cause named to use an excessive
amount of memory, or possibly crash. (CVE-2013-2266)

Note: This update disables the syntax checking of NAPTR (Naming
Authority Pointer) resource records.

This update also fixes the following bug :

* Previously, rebuilding the bind-dyndb-ldap source RPM failed with a
'/usr/include/dns/view.h:76:21: error: dns/rrl.h: No such file or
directory' error. (BZ#928439)

All bind users are advised to upgrade to these updated packages, which
contain patches to correct these issues. After installing the update,
the BIND daemon (named) will be restarted automatically."
