   Technical Cyber Security Alert TA08-162C


Apple Quicktime Updates for Multiple Vulnerabilities

   Original release date: June 10, 2008
   Last revised: --
   Source: US-CERT


Systems Affected

     * Apple Mac OS X running versions of QuickTime prior to 7.5
     * Microsoft Windows running versions of QuickTime prior to 7.5


Overview

   Apple QuickTime contains multiple vulnerabilities as described in the Apple
   Knowledgebase article HT1991. Exploitation of these vulnerabilities could
   allow  a  remote  attacker  to  execute  arbitrary  code  or  cause  a
   denial-of-service condition.


I. Description

   Apple QuickTime prior to version 7.5 has multiple image and media file
   handling vulnerabilities. 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. Apple QuickTime 7.5 addresses these
   vulnerabilities.

   Note that Apple iTunes for Windows installs QuickTime, so any system with
   iTunes may be 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 Apple knowledgebase article HT1991 about the
   security content of QuickTime 7.5


III. Solution

Upgrade QuickTime

   Upgrade to QuickTime 7.5. 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.
