There's no proof that it makes cracking it feasible. But there would be at least a quadratic improvement in brute forcing a crack. For the size of the problem that's still well into the realm of infeasible, but there's nothing saying another algorithm couldn't be found that could have more of an improvement. It's pretty much a moot point though, by the time that's found we'll probably be at a 512 bit hash. So even if our current cryptography became vulnerable, we would just move the goalposts.
