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

Incorrect reference counting could result in an INSIST

Insufficient testing when parsing a message allowed
|
|
records with an incorrect class to be be accepted,
|
|
triggering a REQUIRE failure when those records
|

|
in CVE-2015-8000. [RT #40987]

The following resource record types have been implemented:

AVC, CSYNC, NINFO, RKEY, SINK, SMIMEA, TA, TALINK.

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.

<li class="listitem"><p>
|
|
When loading a signed zone, <span class="command"><strong>named</strong></span> will
|
|
now check whether an RRSIG's inception time is in the future,
|
|
and if so, it will regenerate the RRSIG immediately. This helps
|
|
when a system's clock needs to be reset backwards.

On machines with 2 or more processors (CPU), the default value

of detected processors minus one.

Zone transfers now use smaller message sizes to improve

message compression. This results in reduced network usage.

The Microsoft Windows install tool

<span class="command"><strong>BINDInstall.exe</strong></span> which requires a

non-free version of Visual Studio to be built, now uses two
