    <p>
    ClamAV is an antivirus toolkit. It includes a multi-threaded daemon and
    a command line scanner.
    </p>

  <description>
    <p>
    ClamAV fails to properly scan ZIP files with special headers
    (CAN-2005-0133) and base64 encoded images in URLs.
    </p>
  </description>
  <impact type="normal">
    <p>
    By sending a base64 encoded image file in a URL an attacker could evade
    virus scanning. By sending a specially-crafted ZIP file an attacker
    could cause a Denial of Service by crashing the clamd daemon.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All ClamAV users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=app-antivirus/clamav-0.81"</code>
  </resolution>
