Apparently now they have a "dumbed down" explanation that they wrote in their blog on, of all places, Business Insider (didn't know BI had blogs from CS researchers..)
http://www.businessinsider.com/this-is-why-bitcoin-is-broken-2013-11This whole things sounds fishy to me. Not what they detail, but in the fact of how they released it so publicly. Also the fact that they gave no notice to the developers that they found this and were planning on publicizing it:
I'm short on time, and this was announced to the public without advanced notice to e.g. the bitcoin-security list. Making an informed response fast is hard.
IIRC, there was an issue found a few months ago that had a patched version of bitcoin-qt coded and released before the bug itself was announced. Wouldn't that have been a more prudent option?
This sounds like, at best, some guys that are trying to get as much spotlight as possible, and at worst, a planned hit from the sectors most impacted by Bitcoin, which shall remain - anonymous.
