Microsoft Windows Media Player 6.4, Windows Media Format Runtime 7.1 through 11, and Windows Media Services 4.1 and 9 incorrectly associate ISATAP addresses with the Local Intranet zone, which allows remote servers to capture NTLM credentials, and execute arbitrary code through credential-reflection attacks, by sending an authentication request, aka "ISATAP 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 Microsoft Windows Media Player 6.4 allows remote attackers to execute arbitrary code via (1) a crafted ASF file or (2) crafted streaming content, aka "WMP Heap Overflow Vulnerability."
