92% of Windows PCs Vulnerable To Zero-Day Attacks On Flash 286

CWmike writes "More than 9 out of every 10 Windows users are vulnerable to the Flash zero-day vulnerability that Adobe won't patch until Thursday, Danish security company Secunia says. According to Secunia, 92% of the 900,000 users who have recently run the company's Personal Software Inspector (PSI) utility have Flash Player 10 on their PCs, while 31% have Flash Player 9. (The total exceeds 100% because some users have installed both.) The most-current versions of Flash Player — and — are vulnerable to hackers conducting drive-by attacks hosted on malicious and legitimate-but-compromised sites. Antivirus vendors have reported hundreds, in some cases thousands, of sites launching drive-bys against Flash."

    This is the reason why we either need diversity in software or OSS. Flash is installed on practically ever computer, and for good reason, many sites require Flash. However relying on a single software and single software versions is a bad idea, even more so when it is closed-source.

    This makes FlashBlock all the more useful. No flash that I don't explicitly enable ever runs in my browser, which should stop these drive-by attacks in their tracks (unless they somehow infect flash objects I would normally allow, instead of injecting a new "hidden" object into the hacked sites).

    I've always said(for years) that Flash would be the killer infection vector and that its cross platform ubiquity would be the Achilles heel for Linux and Mac.

    This is but a taste of things to come. Flash is an abomination. It has too much power with too little end user control over that power. Combined with its insanely large install base and you have disaster waiting to happen.

    I'm not sorry for being right all the time. So suck it!

  • Flash is installed on almost every PC. The large majority of Windows users still use Internet Explorer, so the majority right there are vulnerable. Firefox has a respectable percentage of the user base, but very few of those people (outside of the Slashdot crowd) seem to use tools like Flashblock. The other browsers - Chrome, Safari, Opera round out the group; their users are pretty much all vulnerable too.

    It's sad, I agree - but we already knew this was the case since we've known about this unpatched flaw

    • Well, given that it's possible to avoid Flashblock just by lying to the browser (since FF3 doesn't do much MIME checking), installing it really doesn't help security significantly.

    You know ...

    I hate Adobe software.

    There, I said it.

    Photoshop is buggy. Premiere is often weird and arcane. Flash and Reader have had some NASTY security holes of late. Reader is a painfully source resource pig. Adobe is at least a year late in releasing a 64 bit version of Flash (outside of the Linux beta).

    You know you're in trouble when freakin' MicroSoft is putting out better software.

    Adobe's releasing one awful update after another. They seem to lack the resources and expertise to maintain a huge portfolio of overly-ambitious software on a wide variety of platforms. They just can't seem to get anything right with their free (as in beer) software from a security, and sometimes even usability, standpoint.

    Dear god.

    Request to Adobe: if you want to be the gateway for rich content on the 'net, please realize what's at stake if you fsck things up. By botching security, you're putting millions of people at risk for having their lives turned upside down by thieves and fraudsters. You're releasing the digital equivalent of Pintos. Please start fixing your mess.

    • I just installed Windows 7 RTM and went to install flash for IE8 (for steam) and Adobe installed a download manager just to install flash. Are they retarded or something? I wish I could ditch Adobe flash for an alternative. I'm already 100% free of Apple software, it would be nice to coup de grace Adobe from my system as well.

    Flash is now among the top attack vectors for Windows, and it isn't even covered by Windows Update.
    There were 23 reported security issues [] in the last 2 years, including at least 4 browse-and-get-owned vulnerabilities.
    In comparison, Silverlight has had no security bulletins since its 1.0 release (it's now at 3.0).
    This may be just yet another reason to migrate to Silverlight, especially for intranet applications.
    • Flash's record is pretty bad, but Silverlight hasn't been completed tested out in the wild yet because it's not very popular right now. More exploits might be coming as it gets used more. But MS seems to have developed it with security in mind, so let's see what happens.

        The day there is a Silverlight issue (if it doesn't get scraped), I will remember this message.

        Even Java, completely designed around sandboxed virtual machine idea and even invented it had security vulnerabilities.

        Hope you guys are getting paid to post these bullshit.

    • Well, it's unsurprising Silverlight doesn't have any vulnerabilities. Flash runs in its own, custom built virtual machine. Silverlight runs in the .NET virtual machine, which is designed with a sandbox at its core, and generally has been much, much more rigorously audited and tested.

        I have no idea about Silverlight vulnerability track record, but I can assure you that full .NET sandbox can and was successfully broken. I've personally discovered one way to corrupt the stack and execute arbitrary native code from a sandboxed application (such as a WPF browser app). That particular vulnerability has been fixed, and does not affect Silverlight anyway, but it serves as a reminder that VM sandboxes aren't perfect. Java also had its share of problems in that regard (though IIRC .NET had far l

      Guess what, DejaVu viewer has no known security issues too.

      Once upon a time, MS puppets were doing their dirty job with more clever methods.

    • ANY piece of software is going to have vulnerabilities -- and the more widespread it is the more people are going to strive to find those vulnerabilities. Silverlight will be no different if it takes over. The "security" of a piece of software is directly related to how diligent the devs are in patching holes. With closed source software, this is an extremely intensive process, so Silverlight is bound to be every bit as bad as Flash. Open source will ALWAYS be more secure, as you can have millions of eyes s
    • So, are you saying Windows is not done until Adobe is broke, so that people will use M$ stuff instead? They have done that before. I don't think Adobe is at fault, since the same problem appears many times for them, but no issues on Silverlight. Interesting, Adobe works on the Mac and Linux flawlessly. So it's got to be the evil empire again. Look out for the fine they are going to get now. WOW.

      Silverlight doesn't have any reported issues since not enough people use it for the bad guys to bother investing resources in finding its vulnerabilities. It's related to the same "macs don't get viruses" argument that was floated around right up until the point that macs became popular enough for virus writers to bother with them.

    These bloated plugins seem to also be responsible for 80%-ish of the crashes I have in Mozilla.

    They are the big weakness of the web: what if someone decides to start putting a non-standard format out there that becomes a de facto standard because it's the easiest way to do something?

    Flash seems to be the easiest way to put up an animation.

    PDF is the best format for distributing documents that you don't necessarily want others to edit.

    No one wants to explore alternatives because the content is in these somewhat unwieldy formats.
