Notes for BIND 9.19.25
----------------------
Security Fixes
~~~~~~~~~~~~~~
- Malicious DNS client that sends many queries over TCP but never reads
responses can cause server to respond slowly or not respond at all for other
clients. :cve:`2024-0760` :gl:`#4481`
New Features
~~~~~~~~~~~~
- Added a new statistics variable ``recursive high-water`` that reports
the maximum number of simultaneous recursive clients BIND has handled
while running. :gl:`#4668`
Removed Features
~~~~~~~~~~~~~~~~
- None.
Feature Changes
~~~~~~~~~~~~~~~
- Outgoing zone transfers are no longer enabled by default. An explicit
:any:`allow-transfer` ACL must now be set at the :any:`zone`, :any:`view` or
:namedconf:ref:`options` level to enable outgoing transfers. :gl:`#4728`
Bug Fixes
~~~~~~~~~
- An RPZ response's SOA record TTL was set to 1 instead of the SOA TTL, if
``add-soa`` was used. This has been fixed. :gl:`#3323`
- Potential data races were found in our DoH implementation related
to HTTP/2 session object management and endpoints set object
management after reconfiguration. These issues have been
fixed. :gl:`#4473`
ISC would like to thank Dzintars and Ivo from nic.lv for bringing
this to our attention.
Known Issues

- There are no new known issues with this release. See :ref:`above
