Release Notes for BIND Version 9.10.8

Introduction

   This document summarizes changes since the last production release on
   the BIND 9.10 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.

Legacy Windows No Longer Supported

   As of BIND 9.10.6, Windows XP and Windows 2003 are no longer supported
   platforms for BIND; "XP" binaries are no longer available for download
   from ISC.

Security Fixes

     * When recursion is enabled but the allow-recursion and
       allow-query-cache ACLs are not specified, they should be limited to
       local networks, but they were inadvertently set to match the
       default allow-query, thus allowing remote queries. This flaw is
       disclosed in CVE-2018-5738. [GL #309]

New Features

     * named now supports the "root key sentinel" mechanism. This enables
       validating resolvers to indicate which trust anchors are configured
       for the root, so that information about root key rollover status
       can be gathered. To disable this feature, add root-key-sentinel no;
       to named.conf. [GL #37]

Feature Changes

     * None.

Bug Fixes

     * named now rejects excessively large incremental (IXFR) zone
       transfers in order to prevent possible corruption of journal files
       which could cause named to abort when loading zones. [GL #339]
     * 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]

End of Life

   BIND 9.10 will be supported until June, 2018, at which time this final
   maintenance release will be published for the branch. For those needing
   long-term support, the current Extended Support Version is BIND 9.11,
   which will be supported until at least December, 2021. The current
   stable branch is BIND 9.12. See
   https://www.isc.org/downloads/software-support-policy/ for details of
   ISC's software support policy.
