The problem relates to Chrome’s FileReader API. File Reader is there to allow sites and web services to read files stored on the user’s device. Unfortunately, however, the bug also allows web sites to break out of their quarantined sandbox and even execute malicious code.
What makes this vulnerability more dangerous than others is that it hasn’t merely been discovered in a closed lab environment, like many of the other bugs we report on. Rather than being discovered by security consultants, this bug is already known to be being used in attacks by hackers. This is why Schuh took the specialist action of publishing the problem and advising users to update to the latest version of Chrome immediately. This is why you have to update Google Chrome now.
