Unpatched IE Flaw Extremely Critical

      I agree that story (bug in Sun's Java) should have merited a story, but it's not quite the same level of seriousness as the IE issue. First, I don't think there are nearly as many users of JRE as there are of IE (although I suppose that's arguable since it's preinstalled on a lot of systems), but more importantly, I don't think that the Java hole was published and unpatched for any significant length of time. The article you linked to, after all, is talking about the fix being released and the original hole in the same sentence.

      The IE one is important because it's a pretty gaping flaw in a very popular (or at least often-used, perhaps less liked) piece of software which has remained open and basically exploitable for a very long time since it's been published and everyone and their cousin made aware of it. I even heard a quick mention of it on one of the cable news networks, so there's really no way to argue that the cat's not out of the bag and into the hands of the crackers, and once they're done, script kiddies.

      Out of curiosity, did you hit the x or did you hit cancel?

      IIRC, the JavaScript confirm() function returns three values -- true, false, or null, depending on whether you hit ok, cancel, or x. Unfortunately, most users think x and cancel are the same, and a lot of programmers forget to check for the null -- so when you hit x, you get the default behaviour in the code (whatever that might be).

      The reason you can't interact with firefox until the confirm dialog is finished is actually sort of simple -- it's defined by the W3C to effectively be a page-modal dialog box. The FF developers have made it be a window-modal box. So far so good. So, they COULD make it so that the bookmarks and so forth worked, but that's about all they can legally do... short of adding an option to completely disable JavaScript for that page.

      javascript:alert(confirm("blah"))

    In the Unix world, most daemons that start as root do whatever work needs to be done as root, and then promptly drop the privileges -- usually, I think, by switching to a non-privileged account. QMail, pumped as the most secure SMTP servers out there, makes *extensive* use of this technique.

    Is this type of thing difficult to do in the Windows world? Does FireFox/Opera do it? If not, and it's possible, why not? How difficult is it to create a 'Firefox' user with NO privs, and have the bulk of the browser run under that ID? Maybe some small part would need to retain privs to write to the user's download area (maybe it can even chroot() to the user's Documents and Settings area?), but most of the browser drops to a non-privileged state.

    Wouldn't this contain most "critical bugs" by allowing the OS kernel (not IE/Firefox) to do the security context checking, instead of the app? Isn't that what kernels are good at?

    I guess the concept I'm looking for is the idea of assuming that there are hundreds of code execution bugs and sandboxing the app as much as possible. It seems this is the way to go for apps written in C/C++, since re-writing them is a definite waste of time.

      Just start it up with an account that already has limited rights, so called "Restricted User". It has exactly two privileges: receiving notifications on filesystem changes, and system shutdown (the latter is easily deactivated).

      You might also use a privileged service to fork(), drop privileges and then spawn a child process. This is what PolicyMaker Application Security does, and because of its granularity it's much safer and more powerful than suid on Unix. Still Windows just offers the mechanism, but no actual userland tool.

      Daemons in Windows either do privilege degradation, or start up in a specialized nobody account. You know, for this sake of dumbness, nobody is usually the second-most powerful account on a Unix system, so Windows has three nobodies - one for local services, one for network services, and one as a plain and straight-forward guest account not used by daemons.

      One of those services is SecondaryLogon, which is the equivalent of sudo under Unix. It changes some privileges in its fork() before launching the actual child process.

      But doing privilege degradation on GUI applications is just stupid, as the GUI allows interchange of all input and output events - you can never be sure, if the user pressed a button or if an evil program just send a WM_MOUSE::BUTTON1_CLICK message. Your degraded browser could be exploited, send a "Press Start, Run, format X:, Enter, Y, Enter" message to the desktop and you disk is fried. No security checks at all!
      Doesn't stop Microsoft from implementing it on IE7 and Windows Vista.

      On Unix, this is hardly better, as X11 behaves quite the same way as long as you don't use the X Security Extension - for almost all cases, you don't. And you don't want to, because it's just stressy and complicated. Just look at how xspy and PrintScreen utilities work on Unix - they're actually Man-in-the-middles for unsecured X11 connections!

      Is this type of thing difficult to do in the Windows world?

      Well, it's not really *relevant* to the "Windows world". The reason most daemons on unix start as root and then change to another user is because to do most "interesting" things on unix - eg: bind to a low port - you have to be root (more accurately, UID==0). Since Windows uses ACLs for just about everything, you can assign privileges for specific things on a per-user basis.

      Basically, the security models of unix and Windows are fundamentally different. On unix, you have to let the code be able to do anything (run as root) then change to another user with fewer privileges. On Windows, you just grant the user the specific privileges they need (in theory at least, most applications aren't written well enough to actually do this).

      Programs can be opened through "Run as..." and launched under a lesser privileged account. Often, the program won't function fully because app developers rarely care about the security of your machine.

      You can of course write a program to shift privileges as you describe, but few people take the time to do this.

      The way it should be done is to deny all privileges by default, and require developers to request privileges as needed. The user could be notified on install or startup the list of the privileges the program is requesting and allow or deny any or all of them. .NET allows this kind of thing, and an end user can go into .NET control panel (or whatever the heck its called), and do this, but by default, apps generally get full privileges after being installed.
