I know about the basic Heartbleed vulnerability and it's consequences and cause. However, I recently read that Heartbleed may cause a server to crash. I am wondering if this statement is true and if so, why is that so.
As far as I understand Heartbleed simply sends back the length the client requested and misses to check if this length is actually true. So I don't see really how it could be possible to crash the server by reading data?
