Removed Features
~~~~~~~~~~~~~~~~
- The :any:`dnssec-must-be-secure` option has been deprecated and will be
removed in a future release. :gl:`#4263`
- The :any:`dnssec-must-be-secure` option has been deprecated and will
be removed in a future release. :gl:`#4263`
Feature Changes
~~~~~~~~~~~~~~~
- Make :iscman:`nsupdate` honor the ``-v`` option. If set, and the server is
specified, SOA queries are now send over TCP as well. :gl:`#1181`
- If the ``server`` command is specified, :iscman:`nsupdate` now honors
the :option:`nsupdate -v` option for SOA queries by sending both the
UPDATE request and the initial query over TCP. :gl:`#1181`
Bug Fixes
~~~~~~~~~
- The value of If-Modified-Since header in statistics channel was not checked
for length leading to possible buffer overflow by an authorized user. We
would like to emphasize that statistics channel must be properly setup to
allow access only from authorized users of the system. :gl:`#4124`
- The value of the If-Modified-Since header in the statistics channel
was not being correctly validated for its length, potentially allowing
an authorized user to trigger a buffer overflow. Ensuring the
statistics channel is configured correctly to grant access exclusively
to authorized users is essential (see the :any:`statistics-channels`
block definition and usage section). :gl:`#4124`
This issue was reported independently by Eric Sesterhenn of X41 D-SEC and
Cameron Whitehead.

- The value of Content-Length header in statistics channel was not
bound checked and negative or large enough value could lead to
overflow and assertion failure. :gl:`#4125`
- The Content-Length header in the statistics channel was lacking proper
bounds checking. A negative or excessively large value could
potentially trigger an integer overflow and result in an assertion
failure. :gl:`#4125`

- Address memory leaks due to not clearing OpenSSL error stack. :gl:`#4159`
- Several memory leaks caused by not clearing the OpenSSL error stack
were fixed. :gl:`#4159`

- Following the introduction of krb5-subdomain-self-rhs and
ms-subdomain-self-rhs update rules, removal of nonexistent PTR
and SRV records via UPDATE could fail. This has been fixed. :gl:`#4280`
- The introduction of ``krb5-subdomain-self-rhs`` and
``ms-subdomain-self-rhs`` UPDATE policies accidentally caused
:iscman:`named` to return SERVFAIL responses to deletion requests for
non-existent PTR and SRV records. This has been fixed. :gl:`#4280`
- The value of :any:`stale-refresh-time` was set to zero after ``rndc flush``.
This has been fixed. :gl:`#4278`
- The :any:`stale-refresh-time` feature was mistakenly disabled when the
server cache was flushed by :option:`rndc flush`. This has been fixed.
:gl:`#4278`
- BIND could consume more memory than it needs. That has been fixed by
using specialised jemalloc memory arenas dedicated to sending buffers. It
allowed us to optimize the process of returning memory pages back to
the operating system. :gl:`#4038`
- BIND's memory consumption has been improved by implementing dedicated
jemalloc memory arenas for sending buffers. This optimization ensures
that memory usage is more efficient and better manages the return of
memory pages to the operating system. :gl:`#4038`
- Prevent DNS message corruption on long DNS over TLS streams. :gl:`#4255`
- Previously, partial writes in the TLS DNS code were not accounted for
correctly, which could have led to DNS message corruption. This has
been fixed. :gl:`#4255`
