+Notes for BIND 9.16.48
+----------------------
+
+Security Fixes
+~~~~~~~~~~~~~~
+
+- Validating DNS messages containing a lot of DNSSEC signatures could
+  cause excessive CPU load, leading to a denial-of-service condition.
+  This has been fixed. :cve:`2023-50387`
+
+  ISC would like to thank Elias Heftrig, Haya Schulmann, Niklas Vogel,
+  and Michael Waidner from the German National Research Center for
+  Applied Cybersecurity ATHENE for bringing this vulnerability to our
+  attention. :gl:`#4424`
+
+- Preparing an NSEC3 closest encloser proof could cause excessive CPU
+  load, leading to a denial-of-service condition. This has been fixed.
+  :cve:`2023-50868` :gl:`#4459`
+
+- Parsing DNS messages with many different names could cause excessive
+  CPU load. This has been fixed. :cve:`2023-4408`
+
+  ISC would like to thank Shoham Danino from Reichman University, Anat
+  Bremler-Barr from Tel-Aviv University, Yehuda Afek from Tel-Aviv
+  University, and Yuval Shavitt from Tel-Aviv University for bringing
+  this vulnerability to our attention. :gl:`#4234`
+
+- Specific queries could cause :iscman:`named` to crash with an
+  assertion failure when ``nxdomain-redirect`` was enabled. This has
+  been fixed. :cve:`2023-5517` :gl:`#4281`
+
+- A bad interaction between DNS64 and serve-stale could cause
+  :iscman:`named` to crash with an assertion failure, when both of these
+  features were enabled. This has been fixed. :cve:`2023-5679`
+  :gl:`#4334`
+
+- Query patterns that continuously triggered cache database maintenance
+  could cause an excessive amount of memory to be allocated, exceeding
+  ``max-cache-size`` and potentially leading to all available memory on
+  the host running :iscman:`named` being exhausted. This has been fixed.
+  :cve:`2023-6516`
+
+  ISC would like to thank Infoblox for bringing this vulnerability to
+  our attention. :gl:`#4383`
+
+Removed Features
+~~~~~~~~~~~~~~~~
+
+- Support for using AES as the DNS COOKIE algorithm (``cookie-algorithm
+  aes;``) has been deprecated and will be removed in a future release.
+  Please use the current default, SipHash-2-4, instead. :gl:`#4421`
+
