Today, a critical security issue has been discovered in the TeamSpeak 2 server affecting all versions up to 2.0.23.17. The bug could enable an attacker to read files from the filesystem of a host through the TCP query interface. The TeamSpeak development team reacted immediately and a security patch has been distributed. The new release carries version number 2.0.23.19.

We strongly recommend that all administrators update their TeamSpeak servers to the latest version as soon as possible. 

The new release can be found in our download area or on the official TeamSpeak website.

Update - 02 August 2007

From what we've heard, updated installer packages for Windows and Linux are currently being prepared and will be released soon. These new packages will no longer be tagged as BETA. Authorized TeamSpeak Host Providers (ATHPs) have been informed about the situation by TeamSpeak's official sales & licensing provider Triton CI & Associates.
