This document summarizes changes since BIND 9.10.2:
</p>
<p>
BIND 9.10.2-P4 addresses security issues described in
CVE-2015-5722 and CVE-2015-5986.
</p>
<p>
BIND 9.10.2-P3 addresses a security issue described in
CVE-2015-5477.
</p>
<p>
BIND 9.10.2-P2 addresses a security issue described in
CVE-2015-4620.
</p>
<p>
BIND 9.10.2-P1 addressed several bugs that have been identified
in the BIND 9.10 implementation of response-policy zones (RPZ).
The bugs are in code which optimizes searching through multiple
policy zones. In some cases, they can cause RPZ to behave
inefficiently by searching for query matches in more policy
zones than are strictly necessary, or to behave unpredictably
by failing to search a policy zone that should have been
searched. In the worst case, they can lead to assertion
failures, terminating <span><strong class="command">named</strong></span>.

The latest versions of BIND 9 software can always be found at
<a href="http://www.isc.org/downloads/" target="_top">http://www.isc.org/downloads/</a>.
There you will find additional information about each release,
source code, and pre-compiled versions for Microsoft Windows
operating systems.

<li><p>
An incorrect boundary check in the OPENPGPKEY rdatatype
could trigger an assertion failure. This flaw is disclosed
in CVE-2015-5986. [RT #40286]
</p></li>
<li>
<p>
A buffer accounting error could trigger an assertion failure
when parsing certain malformed DNSSEC keys.
</p>
<p>
This flaw was discovered by Hanno B&#50102;eck of the Fuzzing
Project, and is disclosed in CVE-2015-5722. [RT #40212]

<li>
<p>
A specially crafted query could trigger an assertion failure
in message.c.

<p>
This flaw was discovered by Jonathan Foote, and is disclosed
in CVE-2015-5477. [RT #39795]
</p>
</li>
<li>
<p>
On servers configured to perform DNSSEC validation, an
assertion failure could be triggered on answers from
a specially configured server.

This flaw was discovered by Breno Silveira Soares, and is

<li><p>
Asynchronous zone loads were not handled correctly when the
zone load was already in progress; this could trigger a crash
in zt.c. [RT #37573]
</p></li>
<li>
<p>
Several bugs have been fixed in the RPZ implementation:
</p>
<div class="itemizedlist"><ul type="circle">
<li><p>
Policy zones that did not specifically require recursion
could be treated as if they did; consequently, setting
<span><strong class="command">qname-wait-recurse no;</strong></span> was
sometimes ineffective. This has been corrected.
In most configurations, behavioral changes due to this
fix will not be noticeable. [RT #39229]
</p></li>
<li><p>
The server could crash if policy zones were updated (e.g.
via <span><strong class="command">rndc reload</strong></span> or an incoming zone
transfer) while RPZ processing was still ongoing for an
active query. [RT #39415]
</p></li>
<li><p>
On servers with one or more policy zones configured as
slaves, if a policy zone updated during regular operation
(rather than at startup) using a full zone reload, such as
via AXFR, a bug could allow the RPZ summary data to fall out
of sync, potentially leading to an assertion failure in
rpz.c when further incremental updates were made to the
zone, such as via IXFR. [RT #39567]
</p></li>
<li><p>
The server could match a shorter prefix than what was
available in CLIENT-IP policy triggers, and so, an
unexpected action could be taken. This has been
corrected. [RT #39481]
</p></li>
<li><p>
The server could crash if a reload of an RPZ zone was
initiated while another reload of the same zone was
already in progress. [RT #39649]

The end of life for BIND 9.10 is yet to be determined but
will not be before BIND 9.12.0 has been released for 6 months.
