Vulnerabilities in the server of TeamSpeak 3

On multiple vulnerabilities in the server of TeamSpeak 3, version 3.0.13 are documented. This topic was also discussed on in the community of TeamSpeak and an updated version of the server had been released which fixed the vulnerabilities.

Unfortunately that updated caused other problems. If and when a new version will be released is not known at the moment.

The mainboard in my PC which I used so far, an Asus P5Q, is from the beginning of 2009 – so it is about 6 years old now. At the time socket 775 and Intel Core 2 Duo (later Core 2 Quad) were still considered solid technology. Meanwhile there are significantly more powerful processors and a number of technical innovations which the old mainboard does not provide at all – for example UEFI, USB 3 or SATA with 6 GBit/s, which is specifically interesting for using SSDs. I could add USB 3 with an extra controller card but my practical expierences with that were not the best. Good reasons for me to renew the mainboard with the CPU.
