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

high Nessus Plugin ID 35732

Synopsis

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

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'
