Apple QuickTime heap buffer overflow vulnerability

Overview

Apple QuickTime contains a buffer overflow vulnerability. If exploited, this vulnerability may allow an attacker to execute code.

Description

Apple QuickTime is a media player that includes a browser plugin. Color table atoms can set a list of preferred colors for displaying movieson clients that only support 256 colors.

From Apple Article ID: 306896 “About the security content of QuickTime 7.3”:
_A heap buffer overflow exists in the parsing of the color table atom when opening a movie file. By enticing a user to open a maliciously crafted movie file, an attacker may cause an unexpected application termination or arbitrary code execution. This update addresses the issue by performing additional validation of color table atoms. _
To exploit this vulnerability, an attacker would have to convince a user to open a specially crafted QuickTime movie which could be hosted on a web page or sent in an email.
