Microsoft Windows Media Player vulnerable to buffer overflow in bitmap processing routine

Vulnerability Note VU#291396

Original Release Date: 2006-02-14 | Last Revised: 2006-03-17

Overview

Microsoft Windows Media Player contains a buffer overflow vulnerability that may allow a remote, unauthenticated attacker to execute arbitrary code on a vulnerable system.

Description

Microsoft Windows Media Player (WMP) is an application that ships with Microsoft Windows systems used to play various types of media files. Windows Media Player fails to properly validate bitmap image files (.bmp), potentially allowing a buffer overflow to occur.

If the size field in the bitmap header is set to set to a value that is less than the actual size of the file, WMP will allocate an under-sized buffer to hold the bitmap. When data is copied to this buffer, the buffer overflow may occur. For more information, please see Microsoft Security Bulletin MS06-005.

Exploit code for this vulnerability is publicly available.

Impact

By persuading a user to open a specially crafted bitmap file with Windows Media Player, an attacker may be able to execute arbitrary code with the privileges of the user.
