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 (WMP) 6.3, when installed on Solaris, installs executables with world-writable permissions, which allows local users to delete or modify the executables to gain privileges.

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".

Windows Media Player (WMP) 8.00.00.4477, and possibly other versions, automatically detects and executes .wmf and other content, even when the file's extension or content type does not specify .wmf, which could make it easier for attackers to conduct unauthorized activities via Trojan horse files containing .wmf content.

Buffer overflow in Microsoft Windows Media Player 6.4 allows remote attackers to execute arbitrary code via a malformed Advanced Streaming Format (ASF) file.

Buffer overflow in Microsoft Windows Media Player 7.1 and earlier allows remote attackers to execute arbitrary commands via a malformed Windows Media Station (.NSC) file.

Windows Media Player 7 and earlier stores Internet shortcuts in a user's Temporary Files folder with a fixed filename instead of in the Internet Explorer cache, which causes the HTML in those shortcuts to run in the Local Computer Zone instead of the Internet Zone, which allows remote attackers to read certain files.

Buffer overflows in Microsoft Windows Media Player 7 and earlier allow remote attackers to execute arbitrary commands via (1) a long version tag in an .ASX file, or (2) a long banner tag, a variant of the ".ASX Buffer Overrun" vulnerability as discussed in MS:MS00-090.
