BIND Stable Version 9.10.4

[dino99]

An important stable version has been released a while back. But Debian has not packaged it yet. Please do. ftp://ftp.isc.org/isc/bind9/9.10.4/RELEASE-NOTES-bind-9.10.4.txt

Security Fixes

     * Duplicate EDNS COOKIE options in a response could trigger an
       assertion failure. This flaw is disclosed in CVE-2016-2088. [RT
       #41809]
     * 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]
     * Certain errors that could be encountered when printing out or
       logging an OPT record containing a CLIENT-SUBNET option could be mishandled, resulting in an assertion failure. This flaw is
       disclosed in CVE-2015-8705. [RT #41397]
     * 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 IPv6 ULA (Universal Local Address) 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.
     * When loading a signed zone, named 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.

Feature Changes

     * Updated the compiled-in addresses for H.ROOT-SERVERS.NET and
       L.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.

Porting Changes

     * The Microsoft Windows install tool BINDInstall.exe which requires a non-free version of Visual Studio to be built, now uses two files (lists of flags and files) created by the Configure perl script
       with all the needed information which were previously compiled in the binary. Read win32utils/build.txt for more details. [RT #38915]

Bug Fixes

     * rndc flushtree now works even if there wasn't a cached node at the specified name. [RT #41846]
     * Don't emit records with zero TTL unless the records were received with a zero TTL. After being returned to waiting clients, the
       answer will be discarded from the cache. [RT #41687]
     * For Windows platforms, the SIT (Source Identity Token) support was restored. (It was mistakenly partially replaced in a previous beta
       with new 9.11 COOKIE support.) [RT #41905]
     * When deleting records from a zone database, interior nodes could be left empty but not deleted, damaging search performance afterward.
       [RT #40997] [RT #41941]
     * 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]
     * Some of the options for GeoIP ACLs, including "areacode",
       "metrocode", and "timezone", were incorrectly documented as "area","metro" and "tz". Both the long and abbreviated versions are now
       accepted.
     * Zones configured to use map format master files can't be used as
       policy zones because RPZ summary data isn't compiled when such
       zones are mapped into memory. This limitation may be fixed in a
       future release, but in the meantime it has been documented, and
       attempting to use such zones in response-policy statements is now a configuration error. [RT #38321]

Thank you for taking the time to report this bug and helping to make Ubuntu better.

Based on Ubuntu's CVE database, as far as I can tell there is no evidence that any of the security fixes you mention affect Xenial or Yakkety. But I cannot tell for sure, so since you're flagging this as "[Security Fixes]" to be safe I'll treat this as a security bug and defer to the security team.

If you just want the package updated, I suggest you separate security issues (for which presumably you want urgent attention, as otherwise you wouldn't flag it as such) from straightforward and routine updates in the development release.

CVE-2016-1285 and CVE-2016-1286 were already fixed by USN-2925-1.
CVE-2016-2088 doesn't affect the version of bind9 already in Ubuntu
CVE-2015-8705 doesn't affect the version of bind9 already in Ubuntu
CVE-2015-8704 was already fixed by USN-2874-1.
CVE-2015-8461 doesn't affect the version of bind9 already in Ubuntu
CVE-2015-8000 was already fixed by USN-2837-1.

Marking bug as a non-security related request.

Cosmic is on 1:9.11.4+dfsg-3ubuntu1 so this is resolved now.
