A new Internet Explorer vulnerability has been found by Inge Henriksen that causes Remote Denial of Service (DoS). This can lead to crashing the affected browser while visiting web sites that have the ‘bad’ HTML code.
The exploit is triggered by bad HTML data combined with a bad XML block…
The source of the bug is basically a null pointer dereference, according to Inge. So, remote code execution is not possible. Moreover, the bug can be triggered just by inserting a one-liner HTML code in any HTML page.
I have tested the bug on MS Windows XP Professional with Service Pack 2 and IE 6.0.2900.2180 and here is what I’ve got.
Other systems that are vulnerable are listed below.
- Microsoft Windows Server 2003 with IE 6.0.2790.0
- Microsoft Windows 2000 Advanced Server 5.00.2195 with Service Pack 4 and IE 5.00.3700.1000
This vulnerability has been known by Microsoft since December 30, 2005 but there is no fix yet until this moment.
