Release Notes for BIND Version 9.11.6-P1

Introduction

   This document summarizes changes since the last production release on
   the BIND 9.11 (Extended Support Version) branch. Please see the CHANGES
   file 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.

License Change

   With the release of BIND 9.11.0, ISC changed to the open source license
   for BIND from the ISC license to the Mozilla Public License (MPL 2.0).

   The MPL-2.0 license requires that if you make changes to licensed
   software (e.g. BIND) and distribute them outside your organization,
   that you publish those changes under that same license. It does not
   require that you publish or disclose anything other than the changes
   you made to our software.

   This requirement will not affect anyone who is using BIND, with or
   without modifications, without redistributing it, nor anyone
   redistributing it without changes. Therefore, this change will be
   without consequence for most individuals and organizations who are
   using BIND.

   Those unsure whether or not the license change affects their use of
   BIND, or who wish to discuss how to comply with the license may contact
   ISC at https://www.isc.org/mission/contact/.

Legacy Windows No Longer Supported

   As of BIND 9.11.2, Windows XP and Windows 2003 are no longer supported
   platforms for BIND; "XP" binaries are no longer available for download
   from ISC.

Security Fixes

     * The TCP client quota set using the tcp-clients option could be
       exceeded in some cases. This could lead to exhaustion of file
       descriptors. This flaw is disclosed in CVE-2018-5743. [GL #615]
