[Full-Disclosure] Re: Regarding the recent Apple advisories and patches

Good call...  I knew it was using an exisiting key and there is really not 
much of a defense for someone decrypting info and then using that info in
whatever way they see fit.  But being that I am not all that familiar with 
the inner workings of iTunes or the mp4 media format, the 'conspiracy 
theorist' in me figured I would throw that out there to see what y'all 
thought.

Thanks,
shawn
