Hello Jeremiah! It's possible that Microsoft made IE8 more stable then IE6, so you have such result with this exploit. Also take into account the hardware of your computer. If your computer is powerful enough, then this attack on IE8 and even on IE6 and IE7 can be not so effective (because it's resource consumption in case of IE as I wrote), as it can be at not powerful computers. And many people in the world have not so powerful computers.

I've tested this DoS on Internet Explorer 8, does not significantly impact my system.-----Original Message----- From: MustLive [mailto:mustlive () websecurity com ua] Sent: Sunday, July 19, 2009 10:33 AM To: bugtraq () securityfocus comSubject: DoS vulnerabilities in Firefox, Internet Explorer, Opera and ChromeHello Bugtraq! I want to warn you about Denial of Service vulnerabilities in Firefox, Internet Explorer, Opera and Chrome. Recently buffer overflow vulnerability in Mozilla Firefox 3.5 was found byAndrew Haynes and Simon Berry-Byrne (http://websecurity.com.ua/3337/). AfterI checked at 16.07.2009 this vulnerability in different browsers, I found that this Denial of Service vulnerability also exists in Firefox 3.0.11, Internet Explorer 6 and Opera 9.52 (and later also in Chrome 2.0.172). DoS: http://websecurity.com.ua/uploads/2009/Firefox,%20IE%20&%20Opera%20DoS%20Exploit2.html With this exploit Firefox crashes, IE6 consumes resources of CPU and RAM,Opera freezes at that consumes resources of CPU and RAM, and Chrome crashes..Vulnerable version is Mozilla Firefox 3.0.11 and previous versions (and alsoFirefox 3.5). Vulnerable version is Internet Explorer 6 (6.0.2900.2180) and previous versions. And potentially next versions (IE7 and IE8).Vulnerable version is Opera 9.52 and previous versions (and potentially nextversions too). Vulnerable version is Google Chrome 2.0.172 and previous versions. At that Google Chrome 1.0.154.48 is not vulnerable - it's possible that vulnerable is only Chrome 2.x. I mentioned about this vulnerability at my site (http://websecurity.com.ua/3338/). Best wishes & regards, MustLive Administrator of Websecurity web sitehttp://websecurity.com.ua
