[openssl-users] CVE-201-0737

2018-04-16 Thread Scott Neugroschl
Hi,

I'm trying to make sure I have grokked this advisory properly.

The advisory says this is a cache timing side channel attack on key generation. 
  So am I correct in assuming that a potential attacker must

1) Already have access to the system
2) Have sufficient privilege to be able to access cache info

Or am I completely mistaken here?

Thanks,

ScottN
