@rosyna But, aside from your example of Flash, where is the code that’s exploiting these bugs?
Rosyna Keller ‏@rosyna Feb 15

@mjtsai The bugs are in the apps. The malicious code is delivered multiple ways. Wikipedia has an article on RCE. https://en.wikipedia.org/wiki/Arbitrary_code_execution …

@rosyna @mjtsai Or touch that file or whatever. But notice that Spotify isn't malicious, in the example it's hijacked and becomes malicious
Rosyna Keller ‏@rosyna Feb 15

@drewthaler @mjtsai That actually happened to Twitter for Mac OS X a few years ago due to an image parsing bug.

@rosyna @drewthaler Even for things that would never be approved in the Mac App Store, so that every Developer ID app can be sandboxed.
Gwynne Raskind ‏@ameaijou Feb 15

@mjtsai @rosyna @drewthaler If such entitlements existed, a lot of Developer ID apps would be on the store.
Michael Tsai ‏@mjtsai Feb 16

@ameaijou @rosyna @drewthaler No, I mean the entitlements should go beyond what Apple would accept in the store.
Rosyna Keller ‏@rosyna Feb 16

@mjtsai @ameaijou @drewthaler There are entitlements non-MAS apps can use that MAS apps can't.
Michael Tsai ‏@mjtsai Feb 16

@rosyna @ameaijou @drewthaler Yes, I’m saying there should be more. I don’t want to run into a road block *after* adopting sandboxing.
Rosyna Keller ‏@rosyna Feb 16

@mjtsai @ameaijou @drewthaler But which ones are missing that you'd run into?
