Description

Google Chrome Browser 0.2.149.27 malicious link DoS Vulnerability. CVE-2008-6995. Dos exploit for windows platform

                                        
                                            ---------------------------------------------------
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.
