explanation
############

Google Services Notifier allows users to view wen they have a new wave and
view a preview of it ....

"Keep you update with Google services like Google Mail,Blogger,Reader,YouTube,
Google Docs, Google Wave etc. More services will be added soon."

If a attacker compose a new mail with html or javascript code in
subject & send it to victim´s the code is executed wen Victim´s click in the
extension to view a preview of mail.

So for exploit we need to compose a "special" mail
for example if we put directly in the mail subject a iframe like
"><iframe src="javascript:alert(location.href);"></iframe>
in the two cases the alert is executed wen try to preview the mail
with the extension :) it is executed in context location.href value is
"about:blank"

For example send a mail With a logout acction in google wave in body
"><iframe src="https://wave.google.com/wave/logout"></iframe>
it closes the sesion on google wave , this is a CSRF.
