<p>Multiple vulnerabilities have been discovered in Mumble:</p>

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>
