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."

Stack-based buffer overflow in Microsoft Windows Media Player 9 and 10 allows remote attackers to execute arbitrary code via a PNG image with a large chunk size.

Heap-based buffer overflow in the bitmap processing routine in Microsoft Windows Media Player 7.1 on Windows 2000 SP4, Media Player 9 on Windows 2000 SP4 and XP SP1, and Media Player 10 on XP SP1 and SP2 allows remote attackers to execute arbitrary code via a crafted bitmap (.BMP) file that specifies a size of 0 but contains additional data.

QUARTZ.DLL in Microsoft Windows Media Player 9 allows remote attackers to write a null byte to arbitrary memory via an AVI file with a crafted strn element with a modified length value.

Windows Media Player 9 and 10, in certain cases, allows content protected by Windows Media Digital Rights Management (WMDRM) to redirect the user to a web site to obtain a license, even when the "Acquire licenses automatically for protected content" setting is not enabled.

The getItemInfoByAtom function in the ActiveX control for Microsoft Windows Media Player 9.0 returns a 0 if the file does not exist and the size of the file if the file exists, which allows remote attackers to determine the existence of files on the local system.

The Microsoft Windows Media Player 9.0 ActiveX control may allow remote attackers to execute arbitrary web script in the Local computer zone via the (1) artist or (2) song fields of a music file, if the file is processed using Internet Explorer.

Multiple buffer overflows in libpng 1.2.5 and earlier, as used in multiple products, allow remote attackers to execute arbitrary code via malformed PNG images in which (1) the png_handle_tRNS function does not properly validate the length of transparency chunk (tRNS) data, or the (2) png_handle_sBIT or (3) png_handle_hIST functions do not perform sufficient bounds checking.

Windows Media Player 9 allows remote attackers to execute arbitrary code via a PNG file containing large (1) width or (2) height values, aka the "PNG Processing Vulnerability."
