Before the 03 July 2014 was possible to crash, freeze and in some cases probably even executing malicious code against all the players in a server or lobby of the games that use the Steam Voip API.

Do you know those games like Grid2 and the Valve ones (HL2, L4D*, Portal*) that allow you to voice chat?
Exactly those.
Even the same Steam client for the voice chat with the friends was vulnerable.

That's what I like of frameworks and libraries.

I created a dll injected in the game process that transformed any affected game in an exploit.

The full details are available in the following PDF:
