It's not an exploit in and of itself. It's there as an informational and debugging tool, but many folks use it for the wrong purposes. There are ways to restrict access to the information (via ACL's), or otherwise modify it to your liking.
With BIND 9, you can use the following to control the output.
version "0.91-Beta-running-as-root-with-loads-of-juicy-exploitable-bugs" ;
So have some fun ;)
