Microsoft Windows Media Player Malformed Skin Header Code Execution Vulnerability

This vulnerability allows attackers to execute arbitrary code on vulnerable installations of Microsoft Windows Media Player. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists while decompressing skin files (.WMZ and .WMD) with malformed headers. During this process the malformed values are used to improperly calculate data which can later allow an attacker to execute code under the rights of the current user.
