Release Notes for BIND Version 9.9.9b1 Introduction 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] End of Life BIND 9.9 (Extended Support Version) will be supported until December, 2017.
