Having looked at the openssl library, I can say it's a miracle it works at all.
Rarely seen such a mess of macros and whatnot, a good showcase of why I think
C is not a good language choice. So, not surprised that it contains leaks :(
OTOH, I think people are hugely exaggerating the problem, considering it was
introduced relatively recently and that I got my security update before it
hit the newspapers.
That is of course not to say that it shouldn't be fixed and people shouldn't bother.
But the way it is presented is more about scaring people than anything else.
