    <p>
    Reinhard Max discovered a boundary error in Tk when processing an
    interlaced GIF with two frames where the second is smaller than the
    first one.
    </p>
  </description>
  <impact type="normal">
    <p>
    A remote attacker could entice a user to open a specially crafted GIF
    image with a Tk-based software, 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 Tk users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=dev-lang/tk-8.4.15-r1&quot;</code>
  </resolution>
