There has been speculation that it's going to mean a whole lot of trouble for the internet world at large.
Firstly, anyone with some knoewledge mayb be able to spot a weakness in the code, allowing for a new virus / trojan / whatever to take advantage of the newly discovered falw.
Then there's programmers, who, after viewing source code my think they should use something similar in their own coding. This of course could lead to big copyright violations and such.
I say everyone stay away from it, because it's not going to help much.
It's amazing that it hasn't been leaked a lot sooner, as a few university teams and such have been given access to the code, to work with. It was only a matter of time.
