GLSA-200902-06 : GNU Emacs, XEmacs: Multiple vulnerabilities

This script is Copyright (C) 2009-2015 Tenable Network Security, Inc.

Synopsis :

The remote Gentoo host is missing one or more security-related

Description :

The remote host is affected by the vulnerability described in GLSA-200902-06
(GNU Emacs, XEmacs: Multiple vulnerabilities)

Morten Welinder reports about GNU Emacs and edit-utils in XEmacs: By
shipping a .flc accompanying a source file (.c for example) and setting
font-lock-support-mode to fast-lock-mode in the source file through
local variables, any Lisp code in the .flc file is executed without
warning (CVE-2008-2142).
Romain Francoise reported a security risk in a feature of GNU Emacs
related to interacting with Python. The vulnerability arises because
Python, by default, prepends the current directory to the module search
path, allowing for arbitrary code execution when launched from a
specially crafted directory (CVE-2008-3949).

Impact :

Remote attackers could entice a user to open a specially crafted file
in GNU Emacs, possibly leading to the execution of arbitrary Emacs Lisp
code or arbitrary Python code with the privileges of the user running
GNU Emacs or XEmacs.

Workaround :

There is no known workaround at this time.

Solution :

All GNU Emacs users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=app-editors/emacs-22.2-r3'
All edit-utils users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=app-xemacs/edit-utils-2.39'
