Google Chrome Browser Vulnerability

Hi,

---------------------------------------------------
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 fails in dealing with the POP EBP instruction when pointed out by the EIP register at 0x01002FF4.
