Tested on Windows Vista SP1 and Windows XP SP3 with Google Chrome (BETA)
Software:
Google Chrome Browser 0.2.149.27
Tested:
Windows XP Professional SP3
Result:
Google Chrome Crashes with All Tabs
Problem:
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 lies in dealing with the POP EBP instruction when pointed out by the
EIP register at 0x01002FF4.
