Chrome's sandbox compromised?

A French security research firm boasted today that it has discovered a two-step process for defeating Google Chrome‘s sandbox, reports Brian Krebs.

A comment has a solution:

Chrome is in fact one of several browsers that I utilize, but each Internet facing application on my system also runs in an “untrusted” state in a DefenseWall sandbox. So when I’m running Chrome, it’s like having a sandbox encapsulated in another sandbox.

And so ad infinitum.
