Microsoft Windows Media Player 6.4, Windows Media Format Runtime 7.1 through 11, and Windows Media Services 4.1, 9, and 2008 do not properly use the Service Principal Name (SPN) identifier when validating replies to authentication requests, which allows remote servers to execute arbitrary code via vectors that employ NTLM credential reflection, aka "SPN Vulnerability."

Microsoft Windows Media Player 7.1, 9, 10, and 11 allows remote attackers to execute arbitrary code via a skin file (WMZ or WMD) with crafted header information that causes a size mismatch between compressed and decompressed data and triggers a heap-based buffer overflow, aka "Windows Media Player Code Execution Vulnerability Parsing Skins."

Unspecified vulnerability in Microsoft Windows Media Player 7.1, 9, 10, and 11 allows remote attackers to execute arbitrary code via a skin file (WMZ or WMD) with crafted header information that is not properly handled during decompression, aka "Windows Media Player Code Execution Vulnerability Decompressing Skins."

Heap-based buffer overflow in the bitmap processing routine in Microsoft Windows Media Player 7.1 on Windows 2000 SP4, Media Player 9 on Windows 2000 SP4 and XP SP1, and Media Player 10 on XP SP1 and SP2 allows remote attackers to execute arbitrary code via a crafted bitmap (.BMP) file that specifies a size of 0 but contains additional data.

The DHTML capability in Microsoft Windows Media Player (WMP) 6.4, 7.0, 7.1, and 9 may run certain URL commands from a security zone that is less trusted than the current zone, which allows attackers to bypass intended access restrictions.

Directory traversal vulnerability in Microsoft Windows Media Player 7.1 and Windows Media Player for Windows XP allows remote attackers to execute arbitrary code via a skins file with a URL containing hex-encoded backslash characters (%5C) that causes an executable to be placed in an arbitrary location.

Buffer overflow in mplay32.exe of Microsoft Windows Media Player (WMP) 6.3 through 7.1 allows remote attackers to execute arbitrary commands via a long mp3 filename command line argument. NOTE: since the only known attack vector requires command line access, this may not be a vulnerability.

Microsoft Windows Media Player versions 6.4 and 7.1 and Media Player for Windows XP allow remote attackers to bypass Internet Explorer's (IE) security mechanisms and run code via an executable .wma media file with a license installation requirement stored in the IE cache, aka the "Cache Path Disclosure via Windows Media Player".

The Windows Media Device Manager (WMDM) Service in Microsoft Windows Media Player 7.1 on Windows 2000 systems allows local users to obtain LocalSystem rights via a program that calls the WMDM service to connect to an invalid local storage device, aka "Privilege Elevation through Windows Media Device Manager Service".
