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>.

An incorrect boundary check in the OPENPGPKEY rdatatype
|
|
could trigger an assertion failure. This flaw is disclosed

in CVE-2015-5986. [RT #40286]
|

|

A buffer accounting error could trigger an assertion failure
|
|
when parsing certain malformed DNSSEC keys.

</p>
|

<p>
|

This flaw was discovered by Hanno B쎶eck of the Fuzzing

A specially crafted query could trigger an assertion failure

<p>

This flaw was discovered by Jonathan Foote, and is disclosed

On servers configured to perform DNSSEC validation, an

assertion failure could be triggered on answers from

a specially configured server.

|

<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]
