Apple details security fixes in iOS 7. And there's a ton of them!

Apple has distributed a list of security fixes in the just-released iOS 7 software update. And it's as long and encompassing as you'd imagine any major platform update would be. I haven't seen them online yet, so I'm reproducing it here for anyone who's urgently interested. When/if Apple posts it to their knowledge base, we'll update and link out.
