      Honestly, there are major flaws in all browsers all the time, they're really complicated software and are the most exposed part of the computer at the moment, so lots of research is put into finding flaws.

      The two continuing problems are:
      1) The use of old versions. IE 6 sucks. No way around it. IE 7 sucks less, and IE 8 has a mix of good and bad things.
      2) The time between updates. Some known IE bugs go patched for a long time, with about a 1 month minimum exploitation window, and often quite a bit longer. FF and especially Chrome are MUCH better about pushing out patches and getting their users to upgrade.

          Oh really? Tracing JIT JavaScript interpreters are trivial? Parsing PNG, GIF, JPEG, SVG, and even more image formats is trivial? The rules for the same origin policy including inheritance to iframes and the like, cross domain access, content encoding, proxies, plugins, memory management, not to mention multiple tabs with concurrent access to all these things.. All these are all trivial to you? Man, I'd use your browser in a second, because no one else can manage the complexity. The standards are nice as far as they go, but not complete and there's lots of legacy crap out there. HTML 5 does codify better parsing behavior and other thigns that have been missing for the standard, but still doesn't cover everything.

          For a very quick overview that just grazes the surface on how hard this stuff is, see the Browser Security Handbook [google.com] by Michal Zalewski.

          Firefox lists 35 security flaws in Firefox 3.5 alone, and that's only been out since June.

          Yes, ActiveX is/was/will be a bad idea, but at least it requires a click through now, and runs with DEP in IE 8. Plugins have the same problems on native code for Firefox and the other browsers too, now that Firefox has market share starting to see a rise in plugins and security flaws there instead.

          Now, I'm not a Windows or IE fanboy, actually I hate the darn thing and run Firefox most of the time. But I do break web software for a living, and know how complex this stuff is and how nobody has it right. Both IE and Chrome have added some interesting security features lately to help contain flaws when they do occur, but nobody has yet written perfect software and there will continue to be security flaws in all browsers.

          The hard part is to understand just how long it takes to get a bug fixed!

          I'm a developer. I write code, lots and lots of code. I'm responsible for a FARKING HUGE pile of code that I maintain for a vertical app with over 100 good-sized customers at a small software company. Our developers crank out code - reams and reams of code! we crank through the bugfixes like there's no tomorrow, and the speed of development is somewhere between crazy and insane.

          But, when you leave this frenetic pace of development, when you leave the zone of developers, and enter the realm of corporate America, you find a completely different world inhabited not by crackerjack coders, but by "IT". People who don't write code, who don't craft solutions, and for whom a bug is a big deal.

          These people don't create solutions, they implement them. They spend lots of time doing research. Addressing a single bug can take days, maybe weeks of time, and certainly not hours! And given this very high cost of bug management, being conservative is suddenly very valuable!

          So, when we decide to switch, for example, from Firefox to Chrome, the only consideration is the bugs we'll find, and any we find we can take care in anywhere from hours to minutes, because we wrote the code in the first place, and it's not a big deal to fix.

          But if you didn't write the code, if it's all gibberish to you anyway, and it's your job to get stuff to work anyway, you become very, very conservative very quickly. A solution may work with IE 6, and may only need a few CSS declarations and maybe a tweak to the .js file to work properly with Firefox/Chrome/IE8, but if you don't know how to make those slight changes, you don't change a goddamn thing.

          Slashotters and other coders would do well to understand these people, as they are many and often in control of the purse strings of potential clients! They are the logical oppositve of the developer: risk averse, terrified of change, and work to avoid anything "interesting" anywhere possible.

        According to TFA, this vulnerability was in IE6.

        No, only IE 5.01 SP4 and IE 8 are not vulnerable without enabling "data execution prevention." The attackers apparently targeted IE 6, but nearly all other versions can be compromised.

        From TFA:

        "A security feature known as data execution prevention, which prevents data loaded into memory from being executed, will block the particular exploits McAfee has observed. But Kurtz warned the vulnerability exists in all versions of IE except for IE 5.01, service pack 4, and that it would be possible for attackers to work around the protection.

        In an advisory, Microsoft recommended people use DEP, which by default is enabled in IE 8 but must be turned on in prior versions. The statement also advised users on Vista and later versions of Windows to run IE in protected mode. The advisory didn't say when an update would be released that patches the vulnerability."

        TBH, I haven't read TFA. If TFA says the vulnerability was in IE6 alone, then I think TFA errs. I've read through 3 different related articles before seeing it come up here on slashdot. The vulnerability is also in IE7 and IE8. The fix is really simple - put your IE security settings up to maximum to prevent any DirectX from running, unless you specifically approve of it.

            That's one point of view. Another is, after 4 to 6 warnings, no one can claim to have been hit by a "drive by" without any warning at all.

            "Look here, stupid. Firefox warned you TWICE that some unknown software could be malware. After which, Windows warned you twice. Look at the logs. You dismissed all four warnings, and purposefully installed this crap onto this machine. I think that we should go up front, and speak to the boss about your willful, and deliberate violation of company rules and policies."

            An incident or six like this would probably motivate some people to READ the warnings, and give them at least a passing thought.

    Make no mistake, China is agressively attacking foreign systems and common software. They are stockpiling these zero-day exploits as potential weapons. They use one until it's discovered and patched, then wait until they have another high priority and then unwrap the next one.

    When you see Symantec or Microsoft reporting an "undisclosed source" on new vulnerabilities, it's usually our own government that reported it after investigating a compromise. It's damn scary just how far the Chinese have wormed into the US corporate and military systems.

They have the power to level the US financial systems, military supply lines, utilities, etc which would quickly ruin the US. The reason they have not?

    Because according to Microsoft, system vulnerability is determined by the following formula:

    Vulnerability = (time of patch - time of discovery) * number of exploits.

    Clearly, since the vulnerability was never publicly discovered, no patch was needed, right? Clearly, since the exploit was never published, it was not a security risk, right?

    For years, those outside the FOSS community behaved as if an unknown or undiscovered (or rather, unpublished) exploit was not a security vulnerability for the purposes of calculating risk. Rather, we were led to believe, by MS and others, that only unpatched systems were vulnerable. For years, I watched as countless IT folks repeated the mantra that a fully patched MS system was just as secure as any other.

    It always seemed obvious to me, but apparently not to others, that risk should be calculated using not on the time of discovery and publication, but rather, upon the ship date of the software. (i.e., a vulnerability discovered 3 years after ship date, but patched a month after discovery means your system was vulnerable for 39 months, instead of only one as the MS method calculated vulnerability.

    I think Google is big enough that people will now recognize that system security is not just a matter of patch early, patch often, but also a characteristic of the entity behind the code. Despite what Microsoft marketing would have you believe, the company can't produce a secure OS because they understand neither the problem, nor even the question.

    The reason Linux is more secure than Windows is due not merely to the fact that it is open source, but also because those who work with UNIX understand the problem of system security. It doesn't mean Linux is perfect, only that it fares much better from a total-risk perspective. Microsoft never really grasped that security was a fundamental system design consideration, rather than a problem to be patched on the back-end of SW development. While they have *tried* to address the security issues (and have been somewhat successful, but only due to their brute-force efforts), they still have a product-design mentality which places ship dates above system quality, and usability above overall security. The fact that they still consider anti-virus software and constant patching a normal part of computing indicates they've failed to grasp the lessons learned of the past 3 decades.

    For Microsoft, security is a checkbox feature, not a way of doing business. Maybe, now that Google was compromised by a type of exploit Microsoft, et al, considered of minimal, if not zero, risk, the world will change its opinion of the acceptability of software requiring constant patches and add-on kludges (i.e. anti-virus sw) just to function normally.

  • ... web sites continue to not warn their IE users about the security vulnerabilities in the clients those users are running. They could warn those users each time they visit with IE. But they don't. It's time the webmasters of the world start to do something about the problem and put a big full page notice in front of all IE based visitors warning them about the troubles with IE and urging them to switch to a safer browser (and give some links, too).

    This is a real mysterious thing for me since I enable DEP in all kinds of configurations, even including Virtual Machines. I use Windows mostly for critical/complex device driven things like phone firmware updates, backups which means dozens of drivers installed.

    I also print via Bonjour under Windows, using a Airport USB shared Epson Laser printer which has a very complex driver.

    There hasn't been a single issue I have seen regarding DEP being enabled for all programs. Even AntiVirus programs doesn't complain.

    So, as we all know, some companies are "more equal" (look to Adobe/Carbon/OS X), which product likely prevents Microsoft from enabling it by default?

    According to Wikipedia, Apple enabled DEP like technology back in OS X 10.4.0 days and nobody even noticed it. I am not seeing any mysterious crashes, performance issues even with software based DEP. So, why on earth DEP is defaulting to off?

    In an advisory, Microsoft recommended people use DEP, which by default is enabled in IE 8 but must be turned on in prior versions.

    To my knowledge, DEP is a setting in Windows, not in IE. Does Microsoft not know it's own product or is this some different setting?
