Valve, a game developer, has recently fixed 4 critical bugs in its Stream game platform. If these flaws were exploited, they could have allowed users to attack their opponent remotely, crashing their opponent’s game client. The Stream service has over 25 million users, acting as a platform for popular games such as Counter Strike: Global Offensive, Dota2 and Half Life. On Thursday the vulnerabilities were discovered in the network library of Stream, also know as Stream Sockets.
