    expressions with Chicken, which could possibly lead to the execution of
    arbitrary code, a Denial of Service or the disclosure of sensitive
    information.

  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All Chicken users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=dev-scheme/chicken-3.1.0"</code>
  </resolution>
