[Info-vax] Intel x86-64 Processor Design Security Vulnerability?

[Stephen Hoffman]

There's speculation around a potential security vulnerability and 
related information embargo, involving various Intel x86-64 processors, 
in the implementations of memory management and speculative execution.

Etc.

The issue appears specific to Intel x86-64 designs, and does not arise 
in the AMD x86-64 designs.

Looks like might know a more by later this week based on other reports; 
the apparent embargo may be nearing its end.

Expect to see some vendor software updates, and probably by next 
Tuesday for the Microsoft Windows folks.  Once the patches for an 
exploit or a design vulnerability start rolling out to folks. the 
associated knowledge of the exploit becomes available to anybody that's 
interested in reversing the patches.
