Several issues have been discovered in mumble, a low latency VoIP
client. The Common Vulnerabilities and Exposures project identifies the
following issues:
CVE-2014-0044
It was discovered that a malformed Opus voice packet sent to a
Mumble client could trigger a NULL pointer dereference or an
out-of-bounds array access. A malicious remote attacker could
exploit this flaw to mount a denial of service attack against a
mumble client by causing the application to crash.
CVE-2014-0045
It was discovered that a malformed Opus voice packet sent to a
Mumble client could trigger a heap-based buffer overflow. A
malicious remote attacker could use this flaw to cause a client
crash (denial of service) or potentially use it to execute
arbitrary code.
The oldstable distribution (squeeze) is not affected by these problems.

tag_insight = "Mumble is a low-latency, high quality voice chat program for gaming. It
features noise suppression, automatic gain control and low latency audio
with support for multiple audio standards. Mumble includes an in-game
overlay compatible with most open-source and commercial 3D applications.
Mumble is just a client and uses a non-standard protocol. You will need
a dedicated server to talk to other users. Server functionality is
provided by the package 'mumble-server'.";

version 1.2.3-349-g315b5f5-2.2+deb7u1.
For the unstable distribution (sid), these problems will be fixed soon.
We recommend that you upgrade your mumble packages.";
