New IE Bug Can Crash Browser

By Ed Oswald | Published March 21, 2006, 10:40 AM

A newly discovered flaw in Internet Explorer can cause the browser to crash when visiting a malicious Web site, security firm Secunia said in an advisory Monday. The flaw was first discovered last week by security researcher Michal Zalewski and posted to a popular security mailing list.

"This might not come as a surprise, but there appears to be a *very* interesting and apparently very much exploitable overflow in Microsoft Internet Explorer," Zalewski wrote in the e-mail.

The problem is caused by an array boundary error in the handling of HTML tags with multiple event handlers. The issue can be exploited to cause Internet Explorer 6 to crash through a specially crafted HTML tag with 94 or more event handlers.

Secunia rates the vulnerability as "not critical," its lowest severity rating, and advised those concerned to avoid untrusted Web sites until the problem is addressed. So far, the problem has been confirmed to exist on a fully patched systems running Internet Explorer 6 with Windows XP Service Pack 2.

Microsoft said it was aware of the vulnerability and was investigating. "At this time, we are not aware of any attacks attempting to use the reported vulnerability," a spokesperson said.

The company would either provide a patch as part of its monthly Patch Tuesday updates, or issue an out-of-cycle update if it feels it is necessary.

IE sucks, it is always crashing or freezing waiting for something to load. Even the Hotmail site sometimes freezes. I guess the advertisements they put there make IE freeze. Get something that is better like opera or firefox.

because IE7's only at beta2 stage and not everyone wants to beta for MS.

IE7 is still Beta 2, that's why. It isn't even supported officially by microsoft yet (meaning you cannot get help regarding IE7 except through the forums, tech support cannot assist). That's a pretty darn good reason, no?

When/If Windows Vista Beta 3 is public, will you be asking why everyone refuses to use it instead of Windows XP? How about Vista RC1? Why haven't you tried FireFox 2.0 Alpha yet? Oh, you aren't using Office 2007 on your mainframe servers yet?

I think I've made my point.

How exactly is this different from normal operation? ;-) I will admit that XP is a lot more stable than previous OSs and IE 6 is a big jump ahead, but I still have problems here and there. How do I know when it's an actual exploit and not just a standard "feature" in IE?

Ho hum. A browser crashes. Seriously, is that a "vulnerability"? This just sounds like a bug to me.

Did you even read the article? It says there is an exploitable overflow. That means not only can you crash the browser, you can craft some code to run on the target machine and voila do whatever you want, install a virus, etc

Fun times for IE, as usual.

I read it. It said in the article the worst that can happen is a crash. It's *very* interesting.
