Microsoft Windows Media Format Runtime 9.0, 9.5, and 11 and Windows Media Services 9.1 and 2008 do not properly parse malformed headers in Advanced Systems Format (ASF) files, which allows remote attackers to execute arbitrary code via a crafted (1) .asf, (2) .wmv, or (3) .wma file, aka "Windows Media Header Parsing Invalid Free Vulnerability."

Microsoft Windows Media Format Runtime 9.0, 9.5, and 11; and Microsoft Media Foundation on Windows Vista Gold, SP1, and SP2 and Server 2008; allows remote attackers to execute arbitrary code via an MP3 file with crafted metadata that triggers memory corruption, aka "Windows Media Playback Memory Corruption Vulnerability."

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."

Heap-based buffer overflow in Windows Media Format Runtime 7.1, 9, 9.5, 9.5 x64 Edition, 11, and Windows Media Services 9.1 for Microsoft Windows 2000, XP, Server 2003, and Vista allows user-assisted remote attackers to execute arbitrary code via a crafted Advanced Systems Format (ASF) file.
