Vulnerability Note VU#822481
Apple Quicktime fails to properly process specially crafted MIDI files
OverviewThe Apple Quicktime player contains a heap buffer overflow vulnerability. This vulnerability may allow an attacker to execute arbitrary code or create a denial-of-service condition.
I. DescriptionApple QuickTime contains a heap buffer overflow vulnerability. This vulnerability may allow an attacker to execute arbitrary code with the privileges of the user running QuickTime. By convincing a user to open a specially crafted midi file with QuickTime, an attacker can trigger the overflow.
Depending on settings, a web browser could automatically open a midi file using Quicktime without user interaction. Apple iTunes includes the QuickTime player.
Note that this vulnerability may be present in QuickTime versions prior to 7.1.5 running on Mac OS X and Microsoft Windows 2000, XP and Vista.
II. ImpactA remote, unauthenticated attacker can execute arbitrary code or create a denial-of-service condition. The crafted file may be supplied on a web page, in an email for the victim to select, or by some other means designed to encourage them to invoke QuickTime on the exploit file.
III. SolutionUpdate
Apple has released an update to address this issue.
Do not allow browsers to open QuickTime automatically
Until updates can be applied, do not allow your web browser to open files associated with QuickTime automatically. Consult your web browser's documentation or the references section of this document for more information.
Do not open multimedia files from untrusted sources
Do not open multimedia files that are from untrusted or unknown sources. For more information, please see Using Caution with Email Attachments.
