Apple Releases Security Updates for QuickTime

Original release date: March 06, 2007
Last revised: –
Source: US-CERT

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.

I. Description

Apple QuickTime 7.1.5 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.

Note that QuickTime ships with Apple iTunes.

For more information, please refer to the Vulnerability Notes
Database.

II. Impact

These vulnerabilities could allow a remote, unauthenticated attacker
to execute arbitrary code or commands and cause a denial-of-service
condition. For further information, please see the Vulnerability Notes
Database.

III. Solution

Upgrade QuickTime

Upgrade to QuickTime 7.1.5. This and other updates for Mac OS X are
available via Apple Update.

On Microsoft Windows the QuickTime built-in auto-update mechanism may
not detect this release. Instead, Windows users should check for
updates using Apple Software Update or install the update manually.

Disable QuickTime in your web browser

An attacker may be able to exploit this vulnerability by persuading a
user to access a specially crafted file with a web browser. Disabling
QuickTime in your web browser will defend against this attack vector.
For more information, refer to the Securing Your Web Browser document.
