DESCRIPTION:
Jokaim has discovered a vulnerability in TeamSpeak Client, which can
be exploited by malicious people to compromise a user's system.

The vulnerability is caused due to an error when processing certain
packets and can be exploited to corrupt memory by e.g. sending a
specially crafted TS2T_VOICE_DATA_CELP_WINDOWS_5_2 packet.

The vulnerability is confirmed in version 2.0.32.60 for Windows.
Other versions may also be affected.

SOLUTION:
Update to version 2.0.33.7, which appears to be unaffected.
Reportedly also fixed in the latest TeamSpeak 3.x version.

PROVIDED AND/OR DISCOVERED BY:
Jokaim, nSense.
