bug#28350: enriched.el code execution

[Paul Eggert]

Thanks for reporting this bug. Since it is a serious security hole I have 
installed a patch by Lars Ingebrigtsen that temporarily disables the problematic 
translations, and that also changes Gnus to not call enriched-decode. For the 
emacs-25 branch the patch is here:

https://git.savannah.gnu.org/cgit/emacs.git/commit/?h=emacs-25&id=9ad0fcc54442a9a01d41be19880250783426db70

and for the master branch the patch is here:

https://git.savannah.gnu.org/cgit/emacs.git/commit/?id=19584f13b1e2e4a778602a8302619ef5c675e68b

As this patch is merely a workaround to close the security hole, I am not 
marking the underlying bug as fixed.

Thank you for reporting the problem.
