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.
