  <description>
    <p>Multiple vulnerabilities have been discovered in Mumble:</p>
    
    <ul>
      <li>A crafted length prefix value can trigger a heap-based buffer
        overflow or NULL pointer dereference in the
        opus_packet_get_samples_per_frame function (CVE-2014-0044)
      </li>
      <li>A crafted packet can trigger an error in the opus_decode_float
        function, leading to a heap-based buffer overflow (CVE-2014-0045)
      </li>
      <li>A crafted SVG referencing local files can lead to resource exhaustion
        or hangs (CVE-2014-3755)
      </li>
      <li>Mumble does not properly escape HTML in some external strings before
        displaying them (CVE-2014-3756)
      </li>
    </ul>
  </description>
  <impact type="high">
    <p>A remote attacker could possibly execute arbitrary code with the
      privileges of the process or cause a Denial of Service condition.
    </p>
  </impact>
  <workaround>
    <p>There is no known workaround at this time.</p>
