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.
