Apple QuickTime Vulnerabilities

   Original release date: September 13, 2006
   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 7.1.3 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.


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.


III. Solution

Upgrade QuickTime

   Upgrade to QuickTime 7.1.3. This and other updates for Mac OS X are
   available via Apple Update.

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.
