Apple Releases Security Updates for QuickTime
Systems Affected
Apple QuickTime on systems running
- Apple Mac OS X
- Microsoft Windows
Overview
Apple QuickTime contains multiple vulnerabilities. Exploitation of these vulnerabilities could allow a remote attacker to execute arbitrary code or cause a denial-of-service condition.
Description
Apple QuickTime 7.2 resolves multiple vulnerabilities in the way Java applets and various types of media files are handled. An attacker could exploit these vulnerabilities by convincing a user to access a specially crafted Java applet 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.
Note that QuickTime ships with Apple iTunes.
