  <background>
    <p>GNU Emacs is a highly extensible and customizable text editor.</p>
  </background>
  <description>
    <p>Multiple vulnerabilities have been discovered in GNU Emacs:</p>
    
    <ul>
      <li>When ‘global-ede-mode’ is enabled, EDE in Emacs automatically
        loads a Project.ede file from the project directory (CVE-2012-0035).
      </li>
      <li>When ‘enable-local-variables’’ is set to ‘:safe’, Emacs
        automatically processes eval forms (CVE-2012-3479).
      </li>
    </ul>
  </description>
  <impact type="normal">
    <p>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.
    </p>
  </impact>
  <workaround>
    <p>There is no known workaround at this time.</p>
  </workaround>
  <resolution>
    <p>All GNU Emacs 24.x users should upgrade to the latest version:</p>
    
    <code>
      # emerge --sync
      # emerge --ask --oneshot --verbose "&gt;=app-editors/emacs-24.1-r1"
    </code>
    
    <p>All GNU Emacs 23.x users should upgrade to the latest version:</p>
    
    <code>
      # emerge --sync
      # emerge --ask --oneshot --verbose "&gt;=app-editors/emacs-23.4-r4"
    </code>
