Paul Eggert reports:

Charles A. Roelli has found a security flaw in the enriched mode in GNU Emacs.

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.
