I. Description

Apple QuickTime 7.1 resolves multiple vulnerabilities in the way different types of image and media files are handled. An attacker could exploit these vulnerabilities by convincing a user to access a specially crafted image or media file with a vulnerable version of QuickTime. Since QuickTime configures most web browsers to handle QuickTime media files, an attacker could exploit these vulnerabilities using a web page.
