Macromedia Flash Player fails to properly validate the frame type identifier read from a "SWF" file

Vulnerability Note VU#146284

Original Release Date: 2005-11-11 | Last Revised: 2006-05-09

Overview

A buffer overflow vulnerability in some versions of the Macromedia Flash Player may allow a remote attacker to execute code on a vulnerable system.

Description

The Macromedia Flash Player is a player for the Flash media format and enables frame-based animations with sound to be viewed within a web browser.

Some versions of the Flash Player, specifically 7.0.53.0 and earlier, contain an array bounds checking error in the way that they handle a frame type identifier read from the Flash (SWF) file. This error can results in a heap memory access vulnerability that could allow an attacker to execute arbitrary code. A maliciously crafted SWF that exploits this vulnerability could be supplied through a web page, for example.

Note that vulnerable versions of the Flash Player are provided with a number of versions of Microsoft Windows, Apple's Mac OS X, and some distributions of the Linux operating systems.

Impact

A remote attacker with the ability to supply a specially crafted SWF file to a vulnerable host may be able to execute arbitrary code on that system. The attacker-supplied code would be executed with the privileges of the user opening the file.
