  <description>
    <p>
    The embedded fork of the GD library introduced a "use-after-free"
    vulnerability in a modification which is specific to libwmf.
    </p>
  </description>
  <impact type="normal">
    <p>
    A remote attacker could entice a user to open a specially crafted WMF
    file, possibly resulting in the execution of arbitrary code with the
    privileges of the user running the application, or a Denial of Service.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All libwmf users should upgrade to the latest version which no longer
    builds the GD library:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=media-libs/libwmf-0.2.8.4-r3"</code>
  </resolution>
