Introduction

   BIND 9.9.9b1 is a beta development release of BIND 9.
   This document summarizes changes since the last production release of
   BIND on the corresponding major release branch.

Download

   The latest versions of BIND 9 software can always be found at
   [1]http://www.isc.org/downloads/. There you will find additional
   information about each release, source code, and pre-compiled versions
   for Microsoft Windows operating systems.

Security Fixes

     * The resolver could abort with an assertion failure due to improper
       DNAME handling when parsing fetch reply messages. This flaw is
       disclosed in CVE-2016-1286. [RT #41753]
     * Malformed control messages can trigger assertions in named and
       rndc. This flaw is disclosed in CVE-2016-1285. [RT #41666]
     * Specific APL data could trigger an INSIST. This flaw is disclosed
       in CVE-2015-8704. [RT #41396]
     * Incorrect reference counting could result in an INSIST failure if a
       socket error occurred while performing a lookup. This flaw is
       disclosed in CVE-2015-8461. [RT#40945]
     * Insufficient testing when parsing a message allowed records with an
       incorrect class to be be accepted, triggering a REQUIRE failure
       when those records were subsequently cached. This flaw is disclosed
       in CVE-2015-8000. [RT #40987]

New Features

     * The following resource record types have been implemented: AVC,
       CSYNC, NINFO, RKEY, SINK, SMIMEA, TA, TALINK.
     * Added a warning for a common misconfiguration involving forwarded
       RFC 1918 and ULA zones.
     * Contributed software from Nominum is included in the source at
       contrib/dnsperf-2.1.0.0-1/. It includes dnsperf for measuring the
       performance of authoritative DNS servers, resperf for testing the
       resolution performance of a caching DNS server, resperf-report for
       generating a resperf report in HTML with gnuplot graphs, and
       queryparse to extract DNS queries from pcap capture files. This
       software is not installed by default with BIND.

Feature Changes

     * Updated the compiled in addresses for H.ROOT-SERVERS.NET.
     * The default preferred glue is now the address type of the transport
       the query was received over.
     * On machines with 2 or more processors (CPU), the default value for
       the number of UDP listeners has been changed to the number of
       detected processors minus one.
     * Zone transfers now use smaller message sizes to improve message
       compression. This results in reduced network usage.
     * named -V output now also includes operating system details.

Bug Fixes

     * When deleting records from a zone database, interior nodes could be
       left empty but not deleted, damaging search performance afterward.
       [RT #40997]
     * The server could crash due to a use-after-free if a zone transfer
       timed out. [RT #41297]
     * Authoritative servers that were marked as bogus (e.g. blackholed in
       configuration or with invalid addresses) were being queried anyway.
       [RT #41321]
