    <p>
    Mike Wiacek of the Google Security Team reported a buffer overflow in
    the ARC2 module when processing a large ARC2 key length.
    </p>
  </description>
  <impact type="normal">
    <p>
    A remote attacker could entice a user or automated system to decrypt an
    ARC2 stream in an application using PyCrypto, possibly resulting in the
    execution of arbitrary code or a Denial of Service.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All PyCrypto users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=dev-python/pycrypto-2.0.1-r8"</code>
