Dear BIND users:

Yesterday, 16 June 2021, we released monthly maintenance snapshot 
releases of
our currently supported release branches of BIND.

Specifically, we released BIND 9.11.33, 9.16.17, and 9.17.14

There's no way to say this that isn't embarrassing, but only after the 
was an error in a recently optimized routine discovered by a user -- an 
that will definitely cause operational problems for almost all server 
who upgrade to either of these affected versions:

- BIND 9.16.17
- BIND 9.17.14

BIND 9.11.33 is NOT affected.

If you have not yet updated to the 16 June releases, we ask that you 
hold off
on any plans to install 9.16.17 or 9.17.14 until replacement releases can be
prepared and tested.

The specific issue in question is being tracked in our issue tracker:


and more information about our plans for issuing replacement releases 
will be
provided later; at the moment our priority is getting the news to parties as
quickly as possible so that those who have not already adopted the new 
can postpone until corrected versions are available.
