Yes, but there is nothing that a program can do to prevent the user from hanging themselves. If an attacker has access to your hardware and user session then they can do almost anything, and at the OS level too. At least Chrome extends the supplied OS security features and doesn't try to re-engineer them from scratch. This makes me more comfortable with Chrome rather than less.
