Well, as always, gera (aka Gerardo Richarte) did something real and useful, he created very quickly a presentation he gave at pacsec. The presentation entitled "MD5 to be considered harmful today" can be found here.
It is a very cool presentation, the slides are not very descriptive if you are not familiar with
md5 and the issue in question (they're only slides after all, not a paper), but he did a lot of cool
things to understand and reproduce (most things he did I did not get :)) what the publicated paper with the new attack was actually saying; the paper was only a page long and only contained a table with some collisions and a very brief explanation.
He did something even better; he created a lot of collisions. For example, he created TWO EXECUTABLE FILES THAT HAVE THE SAME MD5 HASH BUT ARE TOTALLY DIFFERENT APPLICATIONS, that's useful, I say!.
