Re: Testing for Heartbleed mutations, anyone?
No because there is no such thing as Heatbleed mutation.

The Heartbleed bug is a missing boundary check in OpenSSL code - a library that implements TLS, it's not a flaw in the TLS protocol. 

Moving on to servers to test for "advanced mutations" makes no sense at all. Either the patch is applied or it isn't - there are no variants of it. The bug doesn't magially mutate to something else on it's own. There are no other attack vectors. It's not a protocol level flaw, it's flaw in one library that implements the protocol. Other SSL libraries are not vulnerable. This is OpenSSL bug only.

The article uses terminology (mutation, spreading) that also plays on the "heartbleed is a virus" fallacy and as such is not only inaccurate but also dangerously close to being pure FUD.

OpenSSL and other libraries most likely contain other bugs - and more rigorous testing is a very good idea, especially for components that are widely used(/embedded) in core infrastructure products. But that has nothing to do with Heartbleed, it's just common sense.

Heartbleed has caused a lot of panic and misinformation, let's not create any more of it.

Testing for Heartbleed mutations, anyone?
Curious to know if anyone in the Dark Reading Community has moved beyond Heartbleed security patches on to servers to advanced testing for mutations....
