They probably are. However, I also expect them to be related because of Microoft's own decisions of integrating security patches with one another, instead of keeping them more modular: the so called "patch bundle" policy. It's hard to believe that say some Flash bug couldn't be patched because of some other unrelated bug. But I hope Microsoft can prove me wrong and explain in detail next month why it couldn't deliver any of the 20-30+ bug patches because of a couple of other unrelated and broken patches.
