eEye Digital Security has reported a vulnerability in Windows Media Player, which can be exploited by malicious people to compromise a user's system.
The vulnerability is caused due to a boundary error within the processing of bitmap files (.bmp) and can be exploited to cause a heap-based buffer overflow via a specially crafted bitmap file that declares its size as 0.
Successful exploitation allows execution of arbitrary code when a user e.g. visits a malicious web site, opens a malicious bitmap file (Windows Media Player is not the default handler for bitmap files), or opens a file (e.g. Word document) containing a malicious Windows Media Player (.wmp) image.
The following supported products and product combinations are NOT vulnerable:
* Windows Media Player 6.4
* Windows Media Player 10 on Windows Server 2003 SP1
* Windows XP Professional x64 Edition
* Windows Server 2003 (with or without SP1) for Itanium-based systems
* Microsoft Windows Server 2003 x64 Edition
