BIND 9.6-ESV-R10-P1 is the latest production release of BIND 9.6-ESV.
BIND 9.6-ESV is an Extended Support Version of BIND. BIND 9.6-ESV
will be end of life on January 31, 2014.
This document summarizes changes from BIND 9.6-ESV-R9 to BIND
9.6-ESV-R10-P1. Please see the CHANGES file in the source code
release for a complete list of all changes.
The latest versions of BIND 9 software can always be found on
our web site at http://www.isc.org/downloads/all. There you will
find additional information about each release, source code, and
pre-compiled versions for Microsoft Windows operating systems.
Product support information is available on
http://www.isc.org/services/support for paid support options.
Free support is provided by our user community via a mailing
list. Information on all public email lists is available at
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]
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.)
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.
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]
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.
Fixed a memory leak in GSS-API processing. [RT #33574]
Fixed an acache-related race condition that could cause a crash.
rndc now properly fails when given an invalid '-c' argument. [RT
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.
