Hi,

Here is a flaw in just released Google Chrome Browser (Beta). This not a really a "Jail-Break" remote execution type of serious vulnerability (till now, it doesn't seem one) but surely crashes the application (all tabs) and needs a browser restart. But, as a whole the browser surely is very neat and fast!

Google with its own simplicity and creativity, has taken integrated features of top browsers - Firefox, IE, Safari etc. Hope, it didn't catch their bugs too, as the old Carpet Bombing Attack and other speculations going in wild!
 
---------------------------------------------------
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 crashes on "int 3" at 0x01002FF3 as an exception/trap (kernel), followed by "POP EBP" instruction when pointed out by the EIP register at 0x01002FF4.
