Two vulnerabilities have been found in GNU Emacs, possibly leading to user-assisted execution of arbitrary code.

2.  Impact Information


GNU Emacs is a highly extensible and customizable text editor.


Multiple vulnerabilities have been discovered in GNU Emacs:

  • When ‘global-ede-mode’ is enabled, EDE in Emacs automatically loads a Project.ede file from the project directory (CVE-2012-0035).
  • When ‘enable-local-variables’’ is set to ‘:safe’, Emacs automatically processes eval forms (CVE-2012-3479).


A remote attacker could entice a user to open a specially crafted file, possibly resulting in execution of arbitrary code with the privileges of the process or a Denial of Service condition.

3.  Resolution Information


There is no known workaround at this time.


All GNU Emacs 24.x users should upgrade to the latest version:

Code Listing 3.1: Resolution

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=app-editors/emacs-24.1-r1"

All GNU Emacs 23.x users should upgrade to the latest version:

Code Listing 3.2: Resolution

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=app-editors/emacs-23.4-r4"
