    Alfredo Ortega from Core Security Technologies reported a heap-based
    buffer overflow in the strip_escapes() function when processing overly
    long filenames.
    </p>
  </description>
  <impact type="normal">
    <p>
    A remote attacker could entice a user to process specially crafted
    commands with ed or red, possibly resulting in the execution of
    arbitrary code with the privileges of the user running the application.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All GNU ed users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=sys-apps/ed-1.0"</code>
  </resolution>
