That's not a flaw. Such a collision in cryptography exists in all algorithms and it is only considered a flaw if one could spend reasonable amount of computing power and find such collision in reasonable time. Otherwise when it would take something like millions of years we consider it safe.
ok then I'll rename it as an "imperfection" if that satisfies you. an imperfection is anything less than perfection. having collissions means it is not perfect.
now having gotten that out of the way, i don't think just saying something will take millions of years is fully satisfying in the sense that did the people that developed this standard even stop to consider what the actual probabilities for such a thing were and where is their analysis. i doubt it exists.
i'd love to see it though.
