On 25 January 2023 we (Internet Systems Consortium) disclosed three vulnerabilities affecting \
our BIND 9 software:

Operators and package maintainers who prefer to apply patches selectively can find individual \
vulnerability-specific patches in the "patches" subdirectory of each published release \
directory:

- https://downloads.isc.org/isc/bind9/9.16.37/patches/
- https://downloads.isc.org/isc/bind9/9.18.11/patches/
- https://downloads.isc.org/isc/bind9/9.19.9/patches/

With the public announcement of these vulnerabilities, the embargo period is ended and any \
updated software packages that have been prepared may be released.
