Original release date: November 06, 2007
Last revised: --
Source: US-CERT
Systems Affected
Vulnerabilities in Apple QuickTime affect
* 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 7.3 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 that could be hosted on a web
page.
Note that Apple iTunes installs QuickTime, so any system with iTunes
is vulnerable.
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 About the security
content of QuickTime 7.3.
III. Solution
Upgrade QuickTime
Upgrade to QuickTime 7.3. 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.
