Описание
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).
A command injection flaw within the Emacs "enriched mode" handling has been discovered. By tricking an unsuspecting user into opening a specially crafted file using Emacs, a remote attacker could exploit this flaw to execute arbitrary commands with the privileges of the Emacs user.
Меры по смягчению последствий
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))
