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
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]
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-184.108.40.206-1/. 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
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.
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]
