"Charles A. Roelli discovered that Emacs is vulnerable to arbitrary
code execution when rendering text/enriched MIME data (e.g. when using
Emacs-based mail clients).

For Debian 7 'Wheezy', these problems have been fixed in version
23.4+1-4+deb7u1.

We recommend that you upgrade your emacs23 packages.

NOTE: Tenable Network Security has extracted the preceding description
block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues."
