||media-sound/mumble on all architectures
Mumble is low-latency voice chat software intended for use with gaming.
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)
A remote attacker could possibly execute arbitrary code with the
privileges of the process or cause a Denial of Service condition.
There is no known workaround at this time.
All Mumble users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-sound/mumble-1.2.6"
