GDI Vulnerabilities: An Open Letter to Microsoft 444

Posted by michael from the your-call-is-important-to-them dept.
UnderAttack writes "Tom Liston, the guy that brought us the LaBrea Tarpit, wrote an open letter to Microsoft regarding the GDI JPEG vulnerability, and Microsoft's scanning tool for this vulnerability, which he calls 'worse then useless'. Tom, who wrote his own scanning tool, ends his letter with 'Please stop treating your customers like idiots and give us information; information that we can use.' Like Tom explains, the official Microsoft scanning tool misses a lot of vulnerable DLL's installed by third parties, and Microsoft fails to explain if these libraries are a problem or not."

      With 40+ subvariants of the patch, just saying "there's a vunerability on this here machine" without giving the source of the vunerability and the solution to patch said vunerability is dangerous, bordering on the criminally neglient concerning network security.

          Please back up your assertion that this is "bordering" on criminally neglient.

          Analogy: there's a part of your car which could explode at anytime. It's been a long-standing part of your car. This part can manifest itself in different sections of the car or in different accesories added to your car. You which might be able to track down the part(s) if you are an adequate mechanic and you've kept track on where the parts have been put.

          You go back to the manufacturer who says, "Well, we can tell you if you have the part, but we're not sure where on the car, or how many different parts of the car, but you should really get the parts replaced or else the car will blow up".

            You take their word for it, put your car in the shop, then when you go pick it up, the mechanic tells you "OK. We did something, but we won't tell you what we did, and your car may still blow up."

Not that it matters, but its hard to take MS's focus on security seriously when their patching tools won't tell you whether or not you are vulnerable (just that you MAY be vulnerable).

      I totally agree with the 'worse than useless' statement. In my office, I had to disable it on the corporate SUS server because all it did was pop up and worry users. It gives no meaningful information. It does not patch all the dll's that it may or may not find. It merely scares users into thinking they had a virus. This is the only thing in my SUS list that is not approved and it will stay that way forever as far as I am concerned.

      So far, everyone else responding seemed to have missed your point. The article correctly uses "worse than usless". It is the submitter and/or our ever so thorough Slashdot editors to blame for the "worse then useless" grammar mistake.

      And for all of you that missed the grammar mistake and are debating the meaning of "worse than useless", yes, things can be worse than useless. Things can be harmful. They can cause additional harm or frustration, as opposed to a useless item which just does not do anything useful.
    • 'Then' and 'than' used to be the same word (admittedly with an a rather than an e). They were temporarily given a distinct life, but apparently speakers of the language don't think it's worth the effort to maintain a distinction. Fortunately, there's no Academie Anglais, so if you don't like it, keep them distinct in your own speech and writing.

        Of course 3rd party apps might have exploits. It's up to those 3rd party vendors to supply patches. Even if the code is originally based on MS code, the 3rd party vendor may have modified it in any variety of ways and MS has no idea if those will be dangerous versions or not. MS has identified the bad code, the 3rd party vendors have been notified about it. It's up to them to tell you if their version is bad or not, and patch their software.

          If Linus wrote the code, and told the application authors that they were only allowed to use it by accessing a .so file (installed into a special directory for each application that uses it, for no good reason that anyone could gather, and Linus insists that they aren't allowed to modify it in any way), and there was then an update to that .so file, I would expect the update that Linus issued to fix all copies of it, yes.

          Of course, nobody behaves like this in the Linux world. Shared libraries are installed to /lib or /usr/lib and you only have one copy of each of them. An update would ensure that the single copy you depended on had the vulnerability eliminated.

            I believe you missed the zlib buffer overflow, which turned out to be staticly linked into many applications, as well as in the shared library.

            Yeah, not quite the same, since static linking is different (perhaps worse) than having lots of copies of the DLL in different directories, as far as updating is concerned. Also, a different situation because developers had the option to link the way they wanted.

            But to say this sort of thing never happens in the "linux world" and that all library security bugs are easily cured for all apps by updating the shared libs neglects some really unfortunate occurances like the zlib buffer overflow.

      While Microsoft isn't responsible for 3rd party DLLs, this is a different situation. They are partially responsible, and if they were interested in making the client systems secure they would handle things differently for what is really a simple file update.

      Reasons: They designed a system that requires 3rd parties to distribute DLLs that Microsoft created. If the DLLs were set in a well organized location, the updates of the system DLLs would automatically 'fix' the other programs. Versioning -- something that Windows DLLs support and programs can take advantage of -- would handle compatability issues that are not directly incompatable with this fix.

    GDI Vulnerabilities: An open letter to Microsoft

    Dear Redmond Folks:

    When I was but a wee lad, we lived in a rather large, old house that had, among other charming qualities, a basement that would make even the bravest soul think twice before venturing downstairs. It was cavernous, ill lit, and, quite frankly, always smelled a little funny. My older brother, as older brothers are wont to do, would tell me fantastic stories about why the basement had that odor; generally centering on some unfortunate past resident's demise. I hated that basement.

    My parents, in a vain attempt to rid the basement of its malodorous "twang" purchased a dehumidifier which, because there was no electrical outlet anywhere near the floor drain, required emptying on a daily basis.

    And, no matter how many times I begged, bribed and pleaded with my older brother, he would somehow know when I was making my daily trek to the basement and, as I was down there trying to pull the heavy bucket out of the dehumidifier, the lights would suddenly snap off, the basement door would slam shut, and I would hear my older brother's voice wafting down from above: "It's cooooooooming..... It's cooooooooming to get you......."

    And there I stood: alone in the dark, unknown terrors approaching, armed only with a bucket of water.

    Which is, curiously enough, almost exactly the position that Windows users find themselves in today: alone in the dark, unknown terrors approaching, but in their case, having a bucket of water would be an improvement.

    MS04-028 is, perhaps, the epitome of bad technical writing -- the literary equivalent of spaghetti code. I've read through it far too many times, and I still understand far too little.

    Your "GDI Scanning Tool" is worse than useless. Run it, and it tells you that you "may be vulnerable", and directs you to Windows Update and Office Update. Go to Windows Update and update everything you can find. Go to Office Update and do the same. Run the scanner again, and it tells you that you "may be vulnerable", and directs you to Windows Update and Office Update. Lather, rinse, repeat.

    [Which is why the ISC has made GDIScan.exe and GDICLScan.exe available. See http://isc.sans.org/gdiscan.php for details.]

    What about those old gdiplus.dll files that we're all finding in our Side-By-Side DLL directories? Are they a problem? Why are you updating sxs.dll? Is there vulnerable code in there, or did you just rig it to avoid using the bad code in older versions of gdiplus.dll? (Hey, if you had asked me years ago, I would have told you that this was a serious problem with your Side-By-Side implementation.)

    When a third party vendor wants to distribute a Microsoft DLL with their product, don't they have to get permission from you? Wouldn't there be a list somewhere in Redmond of the third party applications that have distributed vulnerable copies of gdiplus.dll? Can you tell us what they are?

    Please stop treating your customers like idiots and give us information; information that we can use.

    In other words: Turn on the lights and open the door. We're ready to come back upstairs now.

    Scanning your own systems for vulnerabilities, especially when you have third-party stuff on it, is a tough job.

    You don't even need third-party stuff or an application to make it hard under Linux. Typical cycle is: kernel version x comes out in March. It's in a Red Hat release in July. Vulnerability found in September, with an immediate release of version x+1 on kernel.org (which also has a lot of changed/evolved drivers etc.) Red Hat back-patches the fix to version x and makes a new funny version number to signify this. They might include a couple other things from x+1 in the back-patch to version x. Except that the funny redhat version number doesn't signify much to anyone on the surface.

    Similar things happen for Red Hat (and other branded linux binary distributions) of Apache, SSL, etc., things that are all quite critical and you'd hope would be crystal-clear as to which patches your version has or doesn't have.

    Now finding whether version X of a library or application has a vulnerability patched usually isn't too hard. And Red Hat does a pretty good job of keeping on top, way better than say Microsoft.

    Disclaimer: I'm no fan of Microsoft, but I'm not a big fan of Red Hat (or, as I prefer, Head Rat) either (or any binary linux/gnu toolchain/popular application distro for that matter).

That "gentleman" could be, for example, the lead scientist in a bio research project and if he asked you a question about something he had detailed knowledge of and you didn't know the answer he, too, could conclude most people are idiots.

      Most users ARE idiots.

      Everyone's an idiot in a field they know little or nothing about. Computer users want their machines to work; they don't want to know how they work, and why should they? You regularly use devices, or the products of devices, that you can't even begin to describe the manner in which they function, yet I don't see engineers or factory workers or mechanics standing up and calling you an idiot for not knowing how these things work, or for not wanting to learn how these things work.

  • I spent about 45 minutes reading docs at MSDN/MSKB trying to find an explicit statement that IE6SP1 on Win98 is vulnerable, and I swear that they don't actually state that fact (explicitly) anywhere! I eventually was able to read between the lines and conclude that Win98 isn't vulnerable, but Win98 + IE6 is, so you should run Windows Update to DL the patch.

    Am I certain? No. Like I said, it's very difficult to find answers to very simple questions in their docs sometimes. I especially hate reading their security bulletins because it's like they were written by very technical lawyers who are trying to maintain the illusion of releasing information without actually doing so.

    It seems that Microsoft, for all its blustery and arrogant, dismissive attitudes toward end users, manages to find itself in a quandary. If it releases too much vulnerability information, it could very well help exploits be written at a faster clip; if too little, then it risks being irrelevant. The timing is tricky too in this case.

    Another problem, though, may have something to do with the audience. Trying to be "all things to all people" (including less-than-clueful admins), it is likely that they decided to "dumb down" the announcement, in short proclaiming that your computer "may be vulnerable". Some could argue that it is language of FUD, but I would say that they are trying to impress on as many people as possible that this is not just another "critical" update. This one is really, really critical.

    I guess I am too smart for my own good... It told me to only check Office update as it seemed to know that I was already up-to-date on the OS side.

    So I go over there and download/install the updates. The only problem I saw with it was that I had to supply my Office CDs during the install (and it warned that might include a key -- luckily I had both in close proximity). If MSFT fucks up I shouldn't be the one that has to produce the CDs/Key to fix it. MSFT should happily go about the update without needing either of those two things. They shouldn't be allowed to check for piracy during a security fix.

    That's at least how I saw it.

    So I was all patched up according to the Windows Update and the Office Update sites and I figured I was done. Maybe I was too smart for my own good?

    Microsoft did not write their own JPEG code; rather they used the freely available implementation from the Independent JPEG group. The flaw is actually in the IJG code, not any Microsoft code.

    Indeed, Netscape, which also uses that code for its JPEG decoding had that flaw (but it was fixed earlier, and of course, it did not make the news nearly as much as this Microsoft issue, owing to its much smaller market share.)

    I have a dumb question. I admit it's a dumb question, because I've spent the last twenty years of my career working with non-Microsoft operating systems and products. The answer may be obvious to someone with that kind of experience, but not to me. So here goes:

    Why the hell are there multiple copies of the same, critical, shared system library floating around on the machine?

    See, where I come from, you have one copy of shared system libraries -- the latest one, with all the latest patches. This library is fully backward-compatible with all its predecessors. Further, the shared system libraries are all in the same place, so you know where to go looking to drop in updates or, if needs be, regressions. (On very, very rare occasions, there'll be a copy of a specific version living alongside the (by definition, broken) application that needs it.) This approach leads to clean system maintenance and ensures that all applications are using the same, up-to-date, best performance, most secure version of the system libraries.

    So why is Windows different? Why are there a zillion copies of GDI+ laying around? And why would you want it that way?

      Back in the day, it was recommended to put all system DLLs into the main system folder and all your custom DLLs into the app folder. But, Windows' awkward design and poor installation utilities led to many system DLLs being overwritten with old or broken versions. You would find yourself with a broken app and really no way to tell what caused it.

      So, to stop the headache, we started putting system DLLs locally, thanks to the path priority built into Windows - it always checks local folders first. And it worked, most of the time. If you asked for a DLL by name and another app was using an incompatible version, you would get still the stinky one. But, if you were first to the call then you knew you would get yours.

      But, the trend had taken root and like any good weed it is hard to get rid of.

      I don't even think this tool is checking for the other sneaky developer trick of renaming the DLLs, either to hide the fact that it's not licensed or other legal yet obscure reasons.

      Actually, that's an excellent question. And believe it or not, the answer actually kinda makes sense.

      The file in question is gdiplus.dll. This file was included in Windows XP and Windows Server 2003, but was not part of previous operating systems.

      Therefore, apps that used this .dll (like Internet Explorer) when installed on previous operating systems (like Windows 2000) had to ship their own copy of the .dll.

    I am surprised that Microsoft does not do what Linux does and have a common DLL provide all the JPEG functionality. At least in Linux, most, if not all apps, use libjpeg.so.

    Fixing a problem like this in Linux is trivial. Only libjpeg needs to be patched, and automagically, all apps that depend on that library are also rendered invulnerable.

    We saw this with png and other shared libraries. Also, offering many of these common libraries as DLLs helps reduce code bloat since every app no longer needs to reinvent the wheel.

      What about programs that have been compiled statically? It wouldn't be a good thing to patch the library and then assume all of your apps are fixed. I realize that not many people do static compilations when they can avoid it, but it does happen in the name of portability, or maybe in the odd binary package where the packager didn't feel
