Microsoft's Urgent Patch Precedes Black Hat Session 232

Julie188 writes "Mystery solved! Microsoft's latest emergency out-of-band patch was weird beyond belief. A notice was sent to journalists and researchers late Friday evening that the patch was coming Tuesday, but Microsoft refused to explain the flaw and even put a cone of silence around researchers who would have otherwise talked about it. But finally, one researcher broke ranks and explained that the patch was caused by a flaw introduced in Microsoft's own development tools. This flaw was also the source of the emergency ActiveX patch, which took about 18 months to complete and which supposedly fixed the problem by turning off ActiveX (setting a 'killbit' on the control). Researchers at Black Hat on Wednesday will be demonstrating how to override the killbit controls and get access to vulnerabilities supposedly stopped with a killbit. What's really scary is that Microsoft has issued 175 killbits fixes so far."

          Mac apps are, like their makers, excessively trendy so whenever a new OS X build is released, the great majority of developers "embrace" the new features and it seems very few are committed to backward compatibility.

            Precisely. With Windows you don't have to upgrade because it has a relatively long support cycle, and as you pointed-out you can continue using Win2000 (or even Win98) without problem. In contrast my Mac 10.4 which is not that old, refuses to run anything because virtually all the software requires 10.5 or higher.

      The thing about Active X is that is just a way to put an object oriented wrapper around a DLL. So really, its just a DLL.

      The problem with DLLs is that they are good for process re-use on a desktop but not the kind of thing you want to be shoving into a browser. However, if Microsoft closed off Active X entirely in browsers, they would break Flash and third party OpenGL and movie plugins... and probably would wind up getting ripped for it.

      The thing to keep in mind is that Firefox and other browsers that allow for DLLs to be loaded as plugins are going to have these problems as well. It's just that, there are less firefox plugins than there are activex controls out there, so the universe of the problem is smaller.

          Strictly speaking, the GP is right. The reason that ActiveX is more vulnerable than Firefox is there are a lot more ActiveX controls than Firefox plugins. (Not to be confused with Firefox Addons, which seem to be fairly secure, and are pieces of javascript. Firefox plugins are things like the PDF viewer that Acrobat installs, etc.)

          However, the reason there are a lot more ActiveX controls is a, tada, bad design. It's because ActiveX fundamentally lets you embed all sorts of stuff that came with the operating system and random applications and were not designed to be controlled by a web page. Stuff around from before web browsers!

          So Microsoft has to kill each of these, one at a time. That's what the '175 killbits' is talking about....something like 125 of those were on things that it should not have been possible to load in a web browser anyway, but Microsoft decided it would be great fun if you could load all those fancy new signed-DLLs-under-another-name in a web browser. And companies that had been putting out ActiveX controls and had never had to worry about security before, because they were selling a PDF rendering control to software developers to embed in their app, suddenly found out how insecure they were.

          Aka, is your car secure, right now? Yes? Alright, let's transport these dangerous criminals in it. What do you mean, it's not secure from that direction?

          And this isn't helped by the fact that ActiveX controls are so easy to install. I'm not talking about malicious ones, those are easy also, but legitimate good ActiveX controls, which are signed by a legit company and everything.

          And they work for two years, and web design moves on...and eventually a hole is discovered in them...and crackers download that version, put it up on their web site, and wait for people to click Yes to install this clearly legit control, signed by Macromedia or whatever, so they can buffer overflow it.

          Oh, look. Have to issue a killbit for that also.

          The large proliferation of ActiveX controls vs. the small proliferation of Netscapian plugins is why ActiveX is so vulnerable, but the first is entirely due to a rather stupid design decision at the start of IE that let web page designers use random ActiveX controls (Which everyone forgets were not invented for web browsers, but existed before as DLLs with well defined embedding mechanisms.) in a web browser

        Well, part of the problem is that ActiveX isn't just used for browser plugins, so there are a huge number of ActiveX controls out there that can be loaded into a browser but really weren't meant for this purpose. Unless the control is marked "safe for scripting", Javascript can't interact with it directly, but it's still loaded.

        There is truth in your argument that third party additions to a browser pose a security problem, but you are comparing coffee and fish.

        Plugins pose a security risk because you are running software from unknown sources as part of your browser. However, you don't need to install the plugins in order to enjoy the browser functionality.

        Active X on the other hand was always intended to be integrate with web pages, which means that in many cases you would not even have been able to view the content without downloading a COM object of dubious origin. Fortunately this has largely failed, and most web content is still accessible without it (though there are a number of commercial services on the other hand that require Active X to work).

        The better comparison with Active X is other dynamic web code, such as scripting languages like javascript, and of course Java, which have been used for similar purposes. There are clear differences, because Active X is running native code, and so is notoriously difficult to sandbox effectively. It is obviously a matter of degree; no system is fully secure. But whereas exploits of Active X tend to often be total (access to the host machine), exploits of systems such as javascript often revolve around more subtle issues such as masquerading.

        I actually think there is merit in having internet distributable native code. But having said that, there are multiple issues. I don't think the solution is merely to improve the containment of the downloaded code (indeed, that only makes it harder for the plugin to do anything useful). The problem is one of trust: how do I know if the binary code is trustworthy (Microsoft rubberstamp certification just doesn't do it for me!); and why do most sites need Active X at all (shouldn't we just be trying to agree on some browser standards like video formats so that typical functionality can be built into the browser!).

        People tend to like to forget about that. ActiveX is no more or less unsafe than FF plugins [mozilla.org]. Executable code running on the client machine, non-sandboxed. Both FF and IE will prompt you before installing such things, and that's the extent of the protection you get from them. Both can be very easily abused by a malicious creator - all you have to do is get people to install it (bunnies!); or install it yourself as part of another application.
