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 (WMP) 9.0 through 11 allows user-assisted attackers to cause a denial of service (application crash) via a malformed (1) MIDI or (2) DAT file, related to "MThd Header Parsing." NOTE: the provenance of this information is unknown; the details are obtained solely from third party information.

Unspecified vulnerability in Microsoft Windows Media Player 11 allows remote attackers to execute arbitrary code via a crafted audio-only file that is streamed from a Server-Side Playlist (SSPL) on Windows Media Server, aka "Windows Media Player Sampling Rate Vulnerability."

Microsoft Windows Media Player (WMP) allows remote attackers to cause a denial of service (application crash) via a certain AIFF file that triggers a divide-by-zero error, as demonstrated by kr.aiff.

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."

Microsoft Windows Media Player 11 (wmplayer.exe) allows user-assisted remote attackers to cause a denial of service (application crash) via a crafted .au file that triggers a divide-by-zero error, as demonstrated by iapetus.au.
