If anyone's wondering why the word "Properly" is in there, it's because they released a band-aid patch and said "All fixed!", when all the band-aid did was break the sample exploit that was presented to them, it did not fix the underlying problem. So the researches fixed the exploit to work around their 'fix'. Then they released another patch and said "All fixed!", except since they blew it in such a half-assed way the first time, nobody really trusts them. (I don't know if subsequent fixes fixed the problem 'properly' or not - but the whole kerfuffle was yet another nail in uTorrent 3.x's acceptance coffin).
