emacs25: fix security issue

GNU Emacs is an extensible, customizable, free/libre text editor and software
environment.  When Emacs renders MIME text/enriched data (Internet RFC 1896), it
is vulnerable to arbitrary code execution. Since Emacs-based mail clients decode
"Content-Type: text/enriched", this code is exploitable remotely. This bug
affects GNU Emacs versions 19.29 through 25.2.

Although we know no efforts to exploit this in the wild, exploitation is easy.
