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 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.

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/):

928027 - CVE-2013-2266 bind: libdns regular expressions excessive resource
 consumption DoS
928439 - building bind-dyndb-ldap error: dns/rrl.h: No such file or directory
