I've created a free server on a website, but I'm a bit cautious on connecting to it. Are there any potential security risks in connecting to a Murmur (Mumble) server?
Any time you exchange data with software you incur a security risk. For example a client could potentially connect o a malicious server that exploits a buffer overflow in the protocol to obtain arbitrary remote code execution on the client. If this is a concerns you find murmur client that wasn't written in C/C++. Managed languages, like python, and java, still suffer from very serious security defects but less than that of C/C++.
