Synopsis

========

 

Multiple vulnerabilities have been found in Mumble, the worst of which

-------------------------------------------------------------------

1 media-sound/mumble < 1.2.6 >= 1.2.6

 

Description

Multiple vulnerabilities have been discovered in Mumble:

 

* 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)

* A crafted packet can trigger an error in the opus_decode_float

function, leading to a heap-based buffer overflow (CVE-2014-0045)

* A crafted SVG referencing local files can lead to resource exhaustion

or hangs (CVE-2014-3755)

* Mumble does not properly escape HTML in some external strings before

displaying them (CVE-2014-3756)

 

Impact
