Security Fixes

   Prevents named from crashing with an INSIST failure when certain
   queries are made against an NSEC3-signed zone. (CVE-2014-0591)
   [RT #35120]

   Treat an all zero netmask as invalid when generating the localnets
   acl. A Winsock library call on some Windows systems can return
   an incorrect value for an interface's netmask, potentially causing
   unexpected matches to BIND's built-in "localnets" Access Control
   List. (CVE-2013-6230) [RT #34687]

   Prevents exploitation of a runtime_check which can crash named
   when satisfying a recursive query for particular malformed zones.
   (CVE-2013-3919) [RT #33690]

Feature Changes

   rndc status now also shows the build-id. [RT #20422]

   Improved OPT pseudo-record processing to make it easier to support
   new EDNS options. [RT #34414]

   "configure" now finishes by printing a summary of optional BIND
   features and whether they are active or inactive. ("configure
   --enable-full-report" increases the verbosity of the summary.)
   [RT #31777]

   Addressed compatibility issues with newer versions of Microsoft
   Visual Studio. [RT #33916]

   Improved the 'rndc' man page. [RT #33506]

   'named -g' now no longer works with an invalid logging configuration.
   [RT #33473]

   The default (and minimum) value for tcp-listen-queue is now 10
   instead of 3.  This is a subtle control setting (not applicable
   to all OS environments).  When there is a high rate of inbound
   TCP connections, it controls how many connections can be queued
   before they are accepted by named.  Once this limit is exceeded,
   new TCP connections will be rejected.  Note however that a value
   of 10 does not imply a strict limit of 10 queued TCP connections
   - the impact of changing this configuration setting will be
   OS-dependent.  Larger values for tcp-listen queue will permit
   more pending tcp connections, which may be needed where there
   is a high rate of TCP-based traffic (for example in a dynamic
   environment where there are frequent zone updates and transfers).
   For most production servers the new default value of 10 should
   be adequate.  [RT #33029]

Bug Fixes

   Fixed the "allow-query-on" option to correctly check the destination
   address. [RT #34590]

   Fix forwarding for forward only "zones" beneath automatic empty
   zones. [RT #34583]

   Remove bogus warning log message about missing signatures when
   receiving a query for a SIG record. [RT #34600]

   Improved resistance to a theoretical authentication attack based
   on differential timing.  [RT #33939]

   The build of BIND now installs isc/stat.h so that it's available
   to /isc/file.h when building other applications that reference
   these header files - for example dnsperf (see Debian bug ticket
   #692467).  [RT #33056]

   Better handle failures building XML for stats channel responses.
   [RT #33706]

   Fixed a memory leak in GSS-API processing. [RT #33574]

   Fixed an acache-related race condition that could cause a crash.
   [RT #33602]

   rndc now properly fails when given an invalid '-c' argument. [RT
   #33571]

   Fixed an issue with the handling of zero TTL records that could
   cause improper SERVFAILs. [RT #33411]

   Fixed a crash-on-shutdown race condition with DNSSEC validation.
   [RT #33573]
