[openssl-users] Two broken SSL_ERROR_WANT_READ/WRITE handling examples - how exploit cpu-hogging and zombification, and, how badly broken do you consider them to be?

2015-02-25 Thread Tinker
Dear list, I have been given two example programs that I have been requested to provide exploits for. I would kindly ask you to suggest me the simplest way to cause as much cpu-hogging in the first one, and zombification in the second, as possible. For causing this, you may use * As serv
