Description:
A vulnerability was reported in Windows Media Center. A remote user may be able to cause arbitrary code to be executed on the target user's system.
A remote user can create a specially crafted DLL file in a directory or on a remote share (e.g., WebDAV, SMB share). When the file is loaded by the target user, the Windows Media Center application may load the remote user's DLL instead of the intended DLL and execute arbitrary code. The code will run with the privileges of the target user.
This type of exploit is also known as "binary planting" or "DLL preloading".
