emacs: command injection flaw within "enriched mode" handling

Published Sep 14, 2017

Description

GNU Emacs before 25.3 allows remote attackers to execute arbitrary code via email with crafted "Content-Type: text/enriched" data containing an x-display XML element that specifies execution of shell commands, related to an unsafe text/enriched extension in lisp/textmodes/enriched.el, and unsafe Gnus support for enriched and richtext inline MIME objects in lisp/gnus/mm-view.el. In particular, an Emacs user can be instantly compromised by reading a crafted email message (or Usenet news article).

Remediation

Red Hat mitigation

This issue can be mitigated by adding the following lines to the Emacs init file (for example ~/.emacs, ~/emacs.d/init.el, site-start.el) and avoiding options that would bypass normal initialization, like 'emacs -Q': ;; Mitigate CVE-2017-14482 in Emacs 25.2 and earlier (require 'enriched) (defun enriched-decode-display-prop (start end &optional param) (list start end))
