"As a proof-of-concept, JavaScript code was written that, when run in the Google Chrome browser, allows JavaScript to read private memory from the process in which it runs"

I am not sure what "the process in which it runs" means here ... do they mean private memory from within chrome ? Or within the child process spawned from chrome, or within the spawned JS sandbox or ... what ?

Practically speaking, I worry about a browser pageview that can read memory from my terminal process. Or from my 'screen' or 'sshd' process.

I think that is not a risk here, yes ?
