Description:
A vulnerability has been reported in Internet Explorer, which can be exploited by malicious people to compromise a user's system.
The vulnerability is caused due to an error within the parsing of WMF images and can be exploited to corrupt system memory.
Successful exploitation allows execution of arbitrary code on a user's system by e.g. tricking the user to visit a malicious web site hosting a specially crafted WMF file or via an email message containing a specially crafted attachment.
The vulnerability has been reported in the following versions:
* Internet Explorer 5.01 Service Pack 4 on Microsoft Windows 2000 Service Pack 4
* Internet Explorer 5.5 Service Pack 2 on Microsoft Windows Millennium.
The vulnerability does not affect the following versions of Windows:

* Windows XP Service Pack 2
* Windows XP Professional x64 Edition

* Windows Server 2003 Service Pack 1
* Windows Server 2003 for Itanium-based Systems
* Windows Server 2003 with Service Pack 1 for Itanium-based Systems
* Windows Server 2003 x64 Edition
NOTE: The vulnerability may also be exploitable through other applications handling WMF images.
