I disagree. Simply opening a file in an unpatched Emacs can run
arbitrary code with zero prompting. This is a massive security risk that
is entirely internal to enriched.el (possibly with the 'display property
more generally). It does get worse that Gnus would trust enriched.el to
decode mail messages too. But anyone using Emacs from 21.1 to 25.2
should be aware of this issue, whether or not they use Emacs for mail.
