It's bad. I decided to test my servers after updating them. Took me about 3 hours to write a working implementation of this attack without any prior knowledge of TLS internals. It's easy to do, pretty much impossible to detect, and it's going to spread quickly. Shut down your https sites and any other TLS services until you've updated OpenSSL, then think about changing your private keys.
