Google Patches 30 Chrome Bugs, Adds Instant Pages

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.'"

    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.

  28. WTF? I need to upgrade my OS to run Chrome 13? by xanthos · · Score: 1

    Fired up chrome this morning on my linux box and it happily told me that I was running an obsolete OS and needed to upgrade.

    I run a highly modified version of debian 5.x on that box that I 'm not going to mess with for the sake of running chrome 13.

    Time to turn off the automated update check I guess.

  31. How much are you saving? by Crag · · Score: 1

    Do you log details of blocked pre-fetches? Do you have data on what portion of blocked pre-fetches were then followed by real visitors? You say "My sites show up plenty fast enough on demand for my visitors, ..." but does that apply well to heavily bandwidth-constrained users? Modems may be old-fashioned, but mobile and wireless users still frequently get poor network performance. Do you have data on how fast all of your visitors download your pages?

    You may well have done all the analysis and come up with the best cost-vs-benefit balanced solution, but I would worry about premature optimization in a situation like this. Pre-fetching doesn't exist at random. It solves a real problem and your defeating of the mechanism has real costs which are less obvious to you than they are to some of your visitors.

    If you have done this analysis, it would make an interesting read and you should submit it as a /. story.

      I'm a contractor, so I've worked on quite a few projects within a relatively short space of time. Few of them block prefetching techniques in practice as far as I know, but several of them keep quite careful metrics about user download performance, particularly those serving multimedia content of one kind or another, and they are certainly healthy enough for their intended user bases without prefetching.

      I'm not arguing that prefetching should always be disabled, BTW, just pointing out a possible reason why some content providers might choose to do so. This is an industry where big players literally remove all of the unnecessary spaces from their HTML files or serve "broken" content with missing closing tags, because a small reduction in file sizes multiplied by a large number of visitors can still equal a significant amount of extra hardware and/or bandwidth you don't have to pay for.

      Obviously that sort of argument doesn't apply to most smaller sites, but then I guess most smaller sites wouldn't know or care about blocking prefetching either.
