No disrespect meant, but from a security perspective the idea of patching security-critical software with a patch from a stranger on the Internet is kind of crazy, isn't it?
Not really. Gatekeepers of important open-source software are usually people who are known in the community and often employed by companies who work in the area.
Let's be honest about it, this patch hasn't got any attention from OpenSSL team yet, but I heard that some people from the team are interested in it. Never got a response, but it looks correct to me.
