A crash can result without user interaction. When a user is made to visit a malicious link, which has an undefined handler followed by a 'special' character, the chrome crashes with a Google Chrome message window "Whoa! Google Chrome has crashed. Restart now?". It fails in dealing with the POP EBP instruction when pointed out by the EIP register at 0x01002FF4.
