Hi,

Lots of information, out there after the embargo was partially lifted 
(all the details have not been revealed).

https://www.forbes.com/sites/thomasbrewster/2018/01/04/google-microsoft-apple-updates-for-meltdown-spectre-intel-processor-vulnerabilities/#7ed5f9c95c3

Meltdown which breaks the most fundamental isolation between user 
applications and the operating system and reportedly effects virtually 
all Intel CPUs. ARM have indicated that the ARM A75 is effected by 
Meltdown, a variant of Meltdown (3a) effects the Cortex A15, A57 and A72 
CPUs. AMD have indicated that they are not vulnerable due to a different 
architecture.

Spectre consists of two variants : -

                  Variant 1 which Intel, ARM and AMD CPU are all 
susceptible to this can be mitigated by OS patching.

                  Variant 2 which Intel and ARM are both susceptible, 
however AMD have indicated that this vulnerability has not been shown.


I suspect there will be additional vulnerabilities announced later, now 
that more people know the types of exploits to use.


Russell
