Obviously, there is a potential for Trojan horses to exploit this

As of Emacs 22, Emacs has a list of local variables that are known to
be safe to set. If a file tries to set any variable outside this
list, it asks the user to confirm whether the variables should be set.
You can also tell Emacs whether to allow the evaluation of Emacs Lisp
code found at the bottom of files by setting the variable
@code{enable-local-eval}.
