Google Chrome 33 update includes 28 security fixes

Google Chrome 33 has undergone a change. The change in status of the browser comes with many updates – especially security fixes. A partial list of changes in the build is available in the SVN revision log that you can find on the official Chrome Release blog.

Google Chrome

According to Google, there are 28 security fixes in this version, including an issue with relative paths in Windows sandbox named pipe policy. The change that tops the list, a “No trespassing” sign: Only extensions or add-ons that originate from the Chrome Web Store, Google’s official distribution channel, can be installed now.

This implies, an ordinary Chrome user can no-longer customize Chrome to fit his/her needs. Earlier, you could set new-tab page as your apps list. That functionality no more exists. In addition, there’s ANOTHER search bar on your page (what’s the point of an omnibox AND a search field?) and capacity to disable the Google API integration has been removed.

  1. Nevertheless, Chrome explains, Chrome 33.0.1750.117 brings a bunch of new features, including Safe mode hotkey start
  2. Better speech synthesis
  3. Blocked local extensions for Windows users
  4. Improved full-screen mode and others.

Erik Kay, director of Chrome engineering, cited

“We believe this change will help those whose browser has been compromised by unwanted extensions.”

The company has paid out over $13,000 in reward money  to folks who reported these vulnerabilities. Here is the list of the bugs discovered by external security researchers fixed in Chrome 33, along with the cash prizes:
