Release Notes for BIND Version 9.12.1rc2

Introduction

   This document summarizes changes since the last production release on
   the BIND 9.12 branch. Please see the CHANGES for a further list of bug
   fixes and other changes.

Download

   The latest versions of BIND 9 software can always be found at
   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

     * update-policy rules that otherwise ignore the name field now
       require that it be set to "." to ensure that any type list present
       is properly interpreted. Previously, if the name field was omitted
       from the rule declaration but a type list was present, it wouldn't
       be interpreted as expected.

Feature Changes

     * named will now log a warning if the old root DNSSEC key is
       explicitly configured and has not been updated. [RT #43670]

Bug Fixes

     * When answering authoritative queries, named does not return the
       target of a cross-zone CNAME between two locally served zones; this
       prevents accidental cache poisoning. This same restriction was
       incorrectly applied to recursive queries as well; this has been
       fixed. [RT #47078]
     * named could crash when acting as a slave for a catalog zone if zone
       contained a master definition without an IP address. [RT #45999]
     * named could crash due to a race condition when rolling dnstap log
       files. [RT #46942]
     * rndc reload could cause named to leak memory if it was invoked
       before the zone loading actions from a previous rndc reload command
       were completed. [RT #47076]

License

   BIND is open source software licenced under the terms of the Mozilla
   Public License, version 2.0 (see the LICENSE file for the full text).

   The license requires that if you make changes to BIND and distribute
   them outside your organization, those changes must be published under
   the same license. It does not require that you publish or disclose
   anything other than the changes you have made to our software. This
   requirement does not affect anyone who is using BIND, with or without

End of Life

   The end-of-life date for BIND 9.12 has not yet been determined.
   However, it is not intended to be an Extended Support Version (ESV)
   branch; accordingly, support will end after the next stable branch
   (9.14) becomes available. Those needing a longer-lived branch are
   encouraged to use the current ESV, BIND 9.11, which will be supported
   until December 2021. See
   https://www.isc.org/downloads/software-support-policy/ for details of
   ISC's software support policy.
