Red Hat Security Advisory

Synopsis: Important: bind security and bug fix update
Advisory ID: RHSA-2009:1180-01
Product: Red Hat Enterprise Linux
Advisory URL: https://rhn.redhat.com/errata/RHSA-2009-1180.html
Issue date: 2009-07-29
CVE Names: CVE-2009-0696
=====================================================================

1. Summary:

Updated bind packages that fix a security issue and a bug are now available
for Red Hat Enterprise Linux 4.

This update has been rated as having important security impact by the Red
Hat Security Response Team.

2. Relevant releases/architectures:

Red Hat Enterprise Linux AS version 4 - i386, ia64, ppc, s390, s390x, x86_64
Red Hat Enterprise Linux Desktop version 4 - i386, x86_64
Red Hat Enterprise Linux ES version 4 - i386, ia64, x86_64
Red Hat Enterprise Linux WS version 4 - i386, ia64, 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 handles dynamic update message packets
containing the "ANY" record type. A remote attacker could use this flaw to
send a specially-crafted dynamic update packet that could cause named to
exit with an assertion failure. (CVE-2009-0696)

Note: even if named is not configured for dynamic updates, receiving such
a specially-crafted dynamic update packet could still cause named to exit
unexpectedly.

This update also fixes the following bug:

* when running on a system receiving a large number of (greater than 4,000)
DNS requests per second, the named DNS nameserver became unresponsive, and
the named service had to be restarted in order for it to continue serving
requests. This was caused by a deadlock occurring between two threads that
led to the inability of named to continue to service requests. This
deadlock has been resolved with these updated packages so that named no
longer becomes unresponsive under heavy load. (BZ#512668)

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

4. Solution:

Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.

This update is available via Red Hat Network. Details on how to use
the Red Hat Network to apply this update are available at
http://kbase.redhat.com/faq/docs/DOC-11259

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

512668 - bind gets hung with 4000 accesses / sec
514292 - CVE-2009-0696 bind: DoS (assertion failure) via nsupdate packets
