      This document summarizes changes since BIND 9.10.2:
    </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>.

<div class="itemizedlist"><ul type="disc">
<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]
	    </p></li>

      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.
