<p>Mumble is low-latency voice chat software intended for use with gaming.</p>
<p>Multiple vulnerabilities have been discovered in Mumble:</p>
<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>A crafted packet can trigger an error in the opus_decode_float
function, leading to a heap-based buffer overflow (CVE-2014-0045)
<li>A crafted SVG referencing local files can lead to resource exhaustion
or hangs (CVE-2014-3755)
<li>Mumble does not properly escape HTML in some external strings before
displaying them (CVE-2014-3756)
<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>There is no known workaround at this time.</p>
<p>All Mumble users should upgrade to the latest version:</p>
# emerge --sync
# emerge --ask --oneshot --verbose "&gt;=media-sound/mumble-1.2.6"
