  • MS-DEFCON 3: Get patched, but beware

    Posted on January 4th, 2013 at 21:20 woody 23 comments

    It’s time to get caught up on your Microsoft patches.

    But there’s a problem. One of the patches is still causing problems – and we have several people posting here with details.

    Usually I try to use a green-light/red-light approach: either I recommend that you avoid all of the current patches, or I recommend that you install all of them. Keeping track of individual patches is a headache for most of you – and I don’t blame you for not wanting to sift through Microsoft’s detritus.

    This month, though, I really don’t have much of an option. The other December 2012 Black Tuesday patches are working well enough, and I figure you really should get them installed. 

    So here’s what I recommend. Go ahead and install all of the outstanding Microsoft patches EXCEPT MS12-078, which is identified in your Update list as KB 2753842. I haven’t heard of any real-world exploits that take advantage of that security hole, but I sure have heard a lot of wailing from people who have been zapped by it.

    While you’re thinking of it, if you run Internet Explorer 6, 7 or 8 (Nota Bene: if you have Windows XP, you are running IE 6, 7 or 8), you need to apply a Microsoft Fixit to plug a gaping hole in IE that’s currently being exploited. 

    A far better solution is to upgrade to IE 9, but if you have Windows XP that isn’t an option.

    To apply the Fixit, go to the Microsoft Security Advisory page, KB 2794220, scroll down and click on the first Fixit link that you see. (The second Fixit on the page is very poorly marked, but it’s the Fixit that undoes the first Fixit.) That’ll run a very simple program that plugs the security hole in IE 6, 7 and 8.

    To recap: Install all outstanding Microsoft patches, except MS12-078 / KB 2753842. And if you’re using IE 6, 7 or 8, and can’t upgrade to IE 9, run the Fixit.

    I’m moving us down to MS-DEFCON 3: Patch reliability is unclear, but widespread attacks make patching prudent. Go ahead and patch, but watch out for potential problems.

    Oh. One other important note. Usually Susan Bradley’s Patch Watch column in Windows Secrets Newsletter only appears in the paid version. (In a unique twist, you get to decide how much you want to pay for a subscription.) This week, though, Patch Watch appears in the free and online versions of the newsletter. If you’ve never read Susan’s columns, you should take a look. They’re by far the best source of understandable, detailed, unbiased advice about Microsoft patches you’ll find anywhere.

    1. Hi Woody, all patched, seemed to take a long time. Should I hide KB 2753842 or just let it keep popping up everyday. Thanks.

    2. Hi Woody,

      I installed all four security patches, including KB 2753842 and have not noticed any problems. (However, I don’t use any of the software in question.)

      Is there anything I should look for in regards to if I might be having an issue I’m unaware of and need to uninstall it?

      Thanks!

    3. So thumb-up on the .NET patches?

      Thanks Woody for your Time Looking at this: Ron

    5. @Ron -

      Looks good. Go for it…

    6. @Tom -

      Yesp. I don’t think they’re going to get any better.

    7. @Jack -

      If you have a problem you’ll see it, probably with a large font in a presentation or some such.

    8. @Dennis -

      No need to hide it. MS will fix it sooner or later – or we’ll find out that it’s OK after all.

    9. Concerning Ron’s comment:

      It’s nice to see that the size of Win XP updates are still measured in kilobytes! Most of the updates for Win 7 and Office 2010 are in the 10 to 30 megabyte range! If you don’t have a fast connection…

      Good luck to all.

    10. Hi Woody,

      I see that the Susan Bradley column (to which you you provided a link) mentions that Microsoft re-released KB2753842 on December 20, and she recommends installing it. However, there several user postings in the Windows Secrets Lounge made after 12/20 that suggest problems with the revised patch.

      Regards,

      M.M.

    11. Woody, I just saw this article about the MS Fix-It for IE 8 and prior. In short, according to the article, the Fix-It doesn’t really, er, fix it, at least not fully. Link is below.

      http://thenextweb.com/microsoft/2013/01/04/researchers-bypass-microsofts-temporary-fix-for-ie6-ie7-and-ie8-vulnerability-patch-still-mia/

    12. @Steven -

      Yep. The bad guys have already bypassed the Fixit. Doesn’t hurt to apply it, but if you use Internet Explorer, your tail’s still hanging in the wind.

    13. @MM -

      And several people here are reporting problems with the new patch, too. Susan’s actively looking into it.

    14. Woody,

      On my Win7 machine there’s a second MS12-078 patch being offered. It is dated 12/11/2012, but this one carries the KB2779030 identifier. Like the problematic one (KB2753842), it purportedly addresses a “remote code execution” problem in Windows Kernel-mode Drivers.

      Do you recommend installing KB2779030? I’m not clear why Microsoft offers multiple patches with different KB numbers but with the same MS identifiers.

      Thanks as always.

      Marty

    15. @Marty -

      This particular security bulletin, MS12-078, fixed two completely different security holes. That’s why there are two KB numbers – a fairly common practice, as MS wants to minimize the number of MS12-xxx security bulletins, for publicity reasons, but needs to separately identify the patches. KB 2779030 appears to be benign. Go for it.

    16. @Woody,

      I was waiting to install KB 2779030 until I saw your comment about it. Today, oddly, that patch is no longer being offered on my Win7 machine. Usually, the previous month’s patches don’t disappear when new ones come out. Perhaps KB 2779030 has been superseded by one of the other patches released on 12/8?

    17. @Marty -

      Could be. It’s also possible that MS has pulled the patch, or that it was installed on your machine but you didn’t realize it…

    18. Is it ok for me to install these windows updates now my comp is running slower than usual?

    19. which updates are safe to install

    20. Forget the FixIt solution from KB2794220.
      Microsoft has just posted MS13-008 (2799329( security updates for IE6, IE7 & IE8, which are way better than the KB2794220 fixit solutions for those affected IE versions.

    21. @linwood -

      At this point I recommend that you refrain from installing any of this month’s patches. None of them are pressing.

      There’s a new Internet Explorer patch, released in the last 24 hours. I’d hold off on that one, too, unless you’re using Internet Explorer 6, 7, or 8 for day-to-day web browsing.

    22. Hi Woody,

      Are you still monitoring KB2753842, which you previously advised against installing? I haven’t seen any go-ahead for this one yet.

      Thanks.

      Regards,

      Marty

    23. @Marty -

      Yep, Microsoft finally fixed that one. Go ahead and install it.
