Apple QuickTime Updates for Multiple Vulnerabilities

Original release date: January 16, 2008
Last revised: –
Source: US-CERT

Systems Affected

 * Apple Mac OS X running versions of QuickTime prior to 7.4
 * Microsoft Windows running versions of QuickTime prior to 7.4

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.

I. Description

Apple QuickTime 7.4 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 that could be hosted on a web
page.

Note that Apple iTunes installs QuickTime, so any system with iTunes
is vulnerable.

II. Impact

These vulnerabilities could allow a remote, unauthenticated attacker
to execute arbitrary code or cause a denial-of-service condition. For
further information, please see About the security content of
QuickTime 7.4.

III. Solution

Upgrade QuickTime

Upgrade to QuickTime 7.4. This and other updates for Mac OS X are
available via Apple Update.

Secure your web browser

To help mitigate these and other vulnerabilities that can be exploited
via a web browser, refer to Securing Your Web Browser.
