  <description>
    <p>
    Ulf Harnhammar and an anonymous German researcher discovered that
    Freshclam fails to check the size of the header data returned by a
    webserver.
    </p>
  </description>
  <impact type="normal">
    <p>
    By enticing a user to connect to a malicious webserver an attacker
    could cause the execution of arbitrary code.
    </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-0.88.2"</code>
  </resolution>
