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."

The DHTML capability in Microsoft Windows Media Player (WMP) 6.4, 7.0, 7.1, and 9 may run certain URL commands from a security zone that is less trusted than the current zone, which allows attackers to bypass intended access restrictions.

Windows Media Player (WMP) 7 and 8, as running on Internet Explorer and possibly other Microsoft products that process HTML, allows remote attackers to bypass zone restrictions and access or execute arbitrary files via an IFRAME tag pointing to an ASF file whose Content-location contains a File:// URL.

A certain Microsoft Windows Media Player 9 Series ActiveX control allows remote attackers to view and manipulate the Media Library on the local system via HTML script.
