I am a bit troubled by the announce that most CPUs out there have a flaw related to kernel mode and priviledge access to memory. The reason why is why should applications store data in memory in the clear? Why shouldn't modern applications store hash and/or encrypted data anytime they are dealing with sensitive data?
So we are supposed to be let known that servers out there host different websites using the same memory base, i.e. shared memory. I think any such website should be shut for endangering their users. Any website worth its salt, pardon the irony (NB : salt is a crypto keyword), should host sensitive data, if in the clear, using non-shared memory, period. And of course, sensitive data should not be stored in the clear, not in the hard drive, not in memory either : it is a matter of good principle.

With those principles implemented, today's cataclismic revelation is just a non-story.
