An issue exists in how chrome behaves with undefined-handlers in chrome.dll version 0.2.149.27. 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 crashes on “int 3” at 0x01002FF3 as an exception/trap, followed by “POP EBP” instruction when pointed out by the EIP register at 0x01002FF4.
