Vulnerabilities don't "magically appear". They're there from the beginning and the goal of the game is to find them and fix them before the bad guys find them and exploit them. If you use a software which isn't maintained, it's insecure not because of its vulnerabilities, but because of its environment, which is ready to attack the vulnerabilities. From a general point of view, it's not risky to use a software from 2005. It's just risky to use it in 2015. Try installing a Flash version from 2005 and open a web browser with it in 2015. That's basically killing your computer, and yet we were all using this Flash version in 2005 without a problem (or almost).
