Release Notes for BIND Version 9.10.5-P1

Introduction

   This document summarizes changes since BIND 9.10.5:

   BIND 9.10.5-P1 addresses the security issues described in CVE-2017-3140

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

   information about each release, source code, and pre-compiled versions
   for Microsoft Windows operating systems.

New DNSSEC Root Key

   ICANN is in the process of introducing a new Key Signing Key (KSK) for
   the global root zone. BIND has multiple methods for managing DNSSEC
   trust anchors, with somewhat different behaviors. If the root key is
   configured using the managed-keys statement, or if the pre-configured
   root key is enabled by using dnssec-validation auto, then BIND can keep
   keys up to date automatically. Servers configured in this way will roll
   seamlessly to the new key when it is published in the root zone.
   However, keys configured using the trusted-keys statement are not
   automatically maintained. If your server is performing DNSSEC
   validation and is configured using trusted-keys, you are advised to
   change your configuration before the root zone begins signing with the
   new KSK. This is currently scheduled for October 11, 2017.

   This release includes an updated version of the bind.keys file
   containing the new root key. This file can also be downloaded from
   https://www.isc.org/bind-keys .

Security Fixes

     * The BIND installer on Windows used an unquoted service path, which
       can enable privilege escalation. This flaw is disclosed in
       CVE-2017-3141. [RT #45229]
     * With certain RPZ configurations, a response with TTL 0 could cause
       named to go into an infinite query loop. This flaw is disclosed in
       CVE-2017-3140. [RT #45181]

End of Life

   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.
