Since it's a 0day I think it would require ninja coders to test, go to the code and fix it in the same day, for complex and legacy code (I think Adobe software falls into these categories), from my experience watching security related lists I can say that generally you publish a measure to mitigate the vulnerability and maybe a workaround before publishing a stable fix. Securing and maintaining software up-to-date in a non-intrusive way is hard in a way that works for all (ie, personal computers and large networks of computers), I think it is also a good business opportunity.
