Bring Down Internet Explorer In Six Words

Marcion writes "Some handy Japanese guy called Hamachiya discovered a bug in Internet Explorer. Under certain conditions, an asterisk when used as a wildcard can crash IE as soon as the user attempts to go to another page." The article claims the "five HTML tags and a CSS declaration" crash IE7 as well as IE6, but I couldn't get IE7 to fail. This page says that as of June, IE6 was at about 37% market share and IE7 under 20%.

      Here's a quick translation I just did:

      Hello! Good afternoon!!!!!
      I stumbled across a browser crash, so today I'll tell you about it!

      Here it is!

      <style>*{position:relative}</style><table><input>< /table>

          Sample (If you're using IE, your browser will close! You have been warned!)

      It seems IE6 or programs using IE6 components will definitely crash!
      I haven't checked IE7 though!

      It seems to be when you have and input or select or such just below a table or tr or such,
      and you use the css wildcard * to set everything to position:relative.

      By the way, if the input has its style directly set to relative, it doesn't crash. What's up with that?
      I don't really get it, but it sure is interesting...!

      Anyone out there who loves Firefox or Opera should go spread this all over and decrease IE's market share!!!

    It indeed crashes IE here... Windows 2K3, IE7 I'm using IE7 bog-standard Windows XP with SP2, and it "crashed" in the manner described for me too. Remember that (as the article states) you have to open a new tab.

    It takes a few seconds to crash after the new tab is opened; that's enough time to type in an auto-completed URL and have it start loading. Strange thing about this is that even though Windows shows the standard "crashed" dialog box for IE, beneath that I can still see (e.g.) Slashdot continue to load in the background until I dismiss the dialog.

      It's not a crash, per se. It's a forced closure due to an illegal operation of one component of the browser with code in mshtml.dll.

      An exception was thrown that was not properly caught. The error is caused by improper error trapping. Otherwise, the browser would just render things improperly or claim there was an error on the page because it doesn't properly parse and render the style tag.

Yes, it's possible to crash IE. Hey, breaking news, you can even crash it in a way that allows you to execute arbitrary code. Wow. Teh horrorz.

    This ain't news. It may be a new hole detected, but could we at least get less lurid subject lines that sound like it's the end of the world? How about "new bug in IE detected"?

      Attitudes like this are why computer security is in such a dismal state. Crashing an application from a remote system means that application is not filtering it's input correctly and is subject to a remote compromise. Just because IE goes bu-bye and starts right up again doesn't mean everything is peaches. By the time you've restarted the app or rebooted windows, you may have already been compromised with the software of choice by the remote. This cold be a backdoor, keylogger, trojan whatever - and you won't even know it other than "my computer is slow". People need to wise-up because malware is getting sneakier and more cost effective for the people that write it.

      Articles like this are news worthy because it brings light to the fact that something is amiss and needs fixing. Unfortunately, other than negative PR, there's little incentive for proprietary software to fix these things. That's one of the reasons IE has been, and still is, such a security nightmare. Firefox is only about 2/3 better (3 pages vs. 8 pages) judging by number of CVEs*. Still, security is about lessening risk. It's foolish to use IE these days with much better options available.

      Umm... 9 days ago?

      http://secunia.com/advisories/26201/

      The vulnerability is caused due to an input validation error within the handling of system default URIs with registered URI handlers (e.g. "mailto", "news", "nntp", "snews", "telnet"). This can be exploited to execute arbitrary commands when a user e.g. using Firefox visits a malicious website with a specially crafted "mailto" URI containing a "%" character and ends in a certain extension (e.g. ".bat", ".cmd")

    First please realize I am no MSFT fanboi, I have been extremely critical of that company in my previous postings.

    MSFT should try to fix the bug that is crashing IE, because crashes in IE have a tendency to become a remote execution bug later. But still, no point in bashing MSFT on this issue. Browsers crashing on malformed input is well known. Firefox, my fav and only browser, too crashes often on malformed input. There is this thing called fuzzing, sending deliberately malformed input to the browser and see what happens. Firefox used to crash more often than IE under fuzzing. Now they provide fuzzing tools for their testers to strengthen mozilla products.

    If it's Trident that's bringing down IE, then you're looking at HTML code that could also bring down Windows Media Player, several versions of Outlook and Outlook Express, MSN Messenger, Steam (from Valve), and other applications which use it to render web pages. I think at least some versions of Winamp used trident as well, but I'm not sure about that.

  14. So? One can easily crash Firefox too... by bradbury · · Score: 3, Informative

    If the point of this item is to point out bugs in IE it isn't alone. I crashed a large Epiphany session with a segmentation violation a couple of days ago and its relatively easy to crash Firefox if you limit the amount of memory available using ulimit (Firefox doesn't catch "early" C++ memory allocation failures and handle them gracefully). Firefox also has the infamous "window unexpectedly destroyed" bug (#263160) for ~3 years (which will crash the browser if you attempt to close the untitled window).

    I suspect all of the Mozilla based browsers will effectively die if one throws enough "heavyweight" pages at them (i.e. those which are activity heavy [because there isn't a Javascript/Active HTML/Animated GIF scheduler]) or run out of swap space (again because memory allocation failures are not handled gracefully).

    IMO, developers place too much emphasis on feature enhancements rather than making the existing browsers run reliably (bugs shouldn't linger for 3 years), with a minimal machine footprint (Netscape 4.7x required significantly less memory than Firefox) and effective priority scheduling of the "top" window (user responsiveness).
