It's not trying to evaluate the whole buffer. Just some
variables which configure Emacs. Those can be set in the
file. Some are considered "safe", some not. In the latter
case you are asked.

See "File Variables" in the Emacs documentation for the
whole story. If you haven't got a local copy, you can
have it online here [1].

You can see them either at the file's very top, or at
its very bottom. Depending on your needs, you can remove
them, configure Emacs to treat them as non-dangerous, or
tell Emacs to ignore all this stuff (cf. configuration
variable `enable-local-variables').
