Microsoft Internet Explorer - Crash on JavaScript "window()"-calling
(05/28/2005)

Description:
There is a bug in Microsoft Internet Explorer, which causes a crash in it.
The bug occurs, because Microsoft Internet Explorer can't handle a call to a
JavaScript-function with the name of the "window"-object.
The bug was fixed in an earlier version. But it works again.

Affected software:
Microsoft Internet Explorer

Workaround:
Deactivate "Active Scripting" in the IE options menu.

Proof-of-Concept exploit:
<body onLoad="window()">

Date of discovery:
11. September 2003

Tested software:
Microsoft Internet Explorer 6 SP2 (6.0.2900.2180.xpsp_sp2_gdr.050301-1519)
on a fully patched Windows XP SP2 system.

DLL versions:
MSHTML.DLL: 6.00.2900.2627 (xpsp_sp2_gdr.050309-1648)
BROWSEUI.DLL: 6.00.2900.2627 (xpsp_sp2_gdr.050309-1648)
SHDOCVW.DLL: 6.00.2900.2627 (xpsp_sp2_gdr.050309-1648)
SHLWAPI.DLL: 6.00.2900.2627 (xpsp_sp2_gdr.050309-1648)
URLMON.DLL: 6.00.2900.2627 (xpsp_sp2_gdr.050309-1648)
WININET.DLL: 6.00.2900.2627 (xpsp_sp2_gdr.050309-1648)

It works with IE 5.5 too (JSCRIPT.DLL version 5.5.0.5207)

Crash confirmed to work on Windows 2000 machine with IE6 6.0.2800.1106
(I believe that would be IE6 SP1).
Said Win2k box is fully patched.
