Who is Vulnerable?	Microsoft Windows 2000 All Versions Microsoft Windows NT 4 Microsoft Windows NT 4 Terminal Server Edition Microsoft Windows Server 2003 Microsoft Windows 2003 Microsoft Windows Server 2003 64-Bit Edition Microsoft Windows Windows 98 Microsoft Windows Windows ME Microsoft Windows XP Microsoft Windows XP 64-bit Edition Microsoft Windows XP SP1
Vulnerability Description	In terms of Microsoft Windows technology, a resource is binary data that can be added to the executable file of a Windows-based application. Graphical images such as icons, cursors and bitmaps are example of standard resources. Windows-based applications support loading and rendering of graphical resources through a set of Application Programming Interface (API) functions. A vulnerability exists in the way Microsoft Windows handles certain image files. The LoadImage API fails to properly validate the image size leading to an integer overflow. This flaw may be exploited by a malicious user to overflow heap memory, potentially leading to arbitrary code execution on the target machine. In a simple exploit attempt, an attack can create a memory access violation in the application which invokes the vulnerable API function. This will terminate the application, creating a denial of service condition. In a more sophisticated attack case, involving code execution, the process flow will be diverted. In such a case, the behaviour of the target is dependent on the attacker's malicious intentions.
