Chrome Bug Upgrades

Google Patches 30 Chrome Bugs, Adds Instant Pages 103

Posted by CmdrTaco from the not-a-bad-month dept.
JohnBert writes "Google patched 30 vulnerabilities in Chrome, paying out the third-highest bounty total ever for the bugs that outsiders filed with its security team. The company packaged the patches with an update to Chrome 13, adding Instant Pages to the 'stable' channel of the browser. The feature, which Google earlier tucked into Chrome 13 previews, proactively pre-loads some search results to speed up browsing. Google last upgraded Chrome's stable build in early June. Like Mozilla, which this year shifted to a rapid-release schedule, Google produces an update about every six-to-eight weeks. Fourteen of the 30 vulnerabilities patched were rated 'high,' the second-most-serious ranking in Google's four-step scoring system, while nine were pegged 'medium' and the remaining seven were labeled 'low.'"

      I added a simple check to my scripts long ago that detected Firefox prefetching and thew a HTTP 403 Forbidden status with a "Prefetching not permitted" message. It was straightforward to detect and block.

      Hopefully Chrome either makes it easy to detect and block, or at least easy to detect.

      As far as i understood, Instant Pages not only prefetch the top-hit in your search, but also renders the page in background.

      The difference is in implementation. Link prefetching was already supported in Chrome (and Firefox), which fetches the page in the background and stores the results in cache. Chrome 13 goes a step farther, actually prerendering the page in the background if requested (including running Javascript).

          I agree - this could be a very serious expoit route. Well meaning sites could easily be spammed with malware site links, and preloading links will completely fubar any sense of trust in that site. Pre-loading is diabolical anyway, for anyone who has a bandwidth cap, and uses it.

        I'm about as pro-privacy as they come on this issue, but even I don't mind a web site doing analytics within its own domain to see which types of content are most popular so they can be prioritised, optimise navigation based on users actual needs, etc. It's the cross-site/cross-visit tracking that is creepy, IMHO, particularly if associated with any other data previously known only to some of those sites.

      The prefetching mechanism passes a special header so anyone in the analytics business will know to ignore those requests.
      • Unfortunately, you don't always want to ignore them. The browser will fetch the page and prerender it. It may or may not then display it. You want to ignore the cases where it doesn't display it, but you don't count the cases where it does. Does it send another request to the server saying 'okay, actually displaying the page now'? If not, then this is going to cause problems for Google's accounting for adverts. My cynical guess is that the fix will be to count prefetch pages when charging advertisers,

  • If the browser starts preloading high ranked pages that I'm not interested in, and do not click on, doesn't that falsely inflate usage statistics on those sites?

      However, it seems to be JavaScript based which, at least to me, is not a desirable way to determine whether or not the page is being pre-loaded.

      At least Firefox sent a "X-moz: prefetch" header which I used to ignore the traffic on those requests.

      • Only if you allow google to place a tracking cookie on your system. Contrast this with how DuckDuckGo handles preferences: the cookie that you set contains a string with one flag for each preference setting, and can be added to the URL if you don't want a cookie. If two users have the same preferences, then they have the same cookie / preferences string, and so can't be tracked based on the cookie.

    For most users the intuition of "don't click on that link" is the last layer of security between the wild west of the Internet and your computer. Prefetching breaks that barrier, and potentially exposes you to any malware writer that's capable enough and determined enough to get their infected (or pwnd) website into the top search results.

    Sorry... although Chrome is decent and maybe more secure than other browsers, until they can promise PERFECT security I don't want to take that chance.

It would pre-fetch the next stumble (this can thankfully be disabled, though it should be noted you would have stumbled to it either way), so I would get a Noscript warning on like a Youtube or Wikipedia page, bit bizarre. Only until I stumbled again and actually landed on the page in question would things become clearer.
