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."

Unspecified vulnerability in Microsoft Office Communications Server (OCS), Office Communicator, and Windows Live Messenger allows remote attackers to cause a denial of service (crash) via a crafted Real-time Transport Control Protocol (RTCP) receiver report packet.

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.

Stack-based buffer overflow in the WMEncProfileManager ActiveX control in wmex.dll in Microsoft Windows Media Encoder 9 Series allows remote attackers to execute arbitrary code via a long first argument to the GetDetailsString method, aka "Windows Media Encoder Buffer Overrun Vulnerability."

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."

An ActiveX control (Messenger.UIAutomation.1) in Windows Messenger 4.7 and 5.1 is marked as safe-for-scripting, which allows remote attackers to control the Messenger application, and "change state," obtain contact information, and establish audio or video connections without notification via unknown vectors.

Stack-based buffer overflow in mplayer2.exe in Microsoft Windows Media Player (WMP) 6.4, when used with the 3ivx 4.5.1 or 5.0.1 codec, allows remote attackers to execute arbitrary code via a certain .mp4 file, possibly a related issue to CVE-2007-6402.

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.

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.

Buffer overflow in the GDI engine in Windows Live Messenger, as used for Windows MSN Live 8.1, allows user-assisted remote attackers to cause a denial of service (application crash or system crash) and possibly execute arbitrary code by placing a malformed file in a new folder under the Sharing Folders path, and triggering a synchronize operation through the Windows MSN Live online service, possibly related to extended file attributes and possibly related to an incomplete fix for MS07-046, as demonstrated by a (1) .jpg, (2) .gif, (3) .wmf, (4) .doc, or (5) .ico file.
