  <impact type="normal">
    <p>
    A remote attacker could exploit the vulnerability to upload
    arbitrary files to a directory where the webserver has write access to,
    possibly leading to the execution of arbitrary code.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All Trac users should upgrade to the latest available version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=www-apps/trac-0.8.4&quot;</code>
