Microsoft Image Processing Vulnerability
The image processing system of Microsoft Windows 2003, XP/Service Pack 1, and some Microsoft and third-party applications have been recently found to contain a buffer overflow vulnerability. Exploits have been identified that permit an external party to take advantage of this vulnerability and gain control over a Windows computer. This buffer overflow vulnerability could be used by a malicious image (e.g., JPEG file) on a Web page or within an email attachment. Microsoft has released patches for Windows 2003, XP/SP1, and selected Microsoft applications (see MS04-028, http://www.microsoft.com/technet/security/Bulletin/MS04-028.mspx).
