Description

Overview

Apple QuickTime contains a heap-based buffer overflow that may allow an attacker to execute arbitrary code or cause a denial-of-service condition.

Description

Apple QuickTime fails to properly validate QuickTime Images (QTIF), potentially allowing a heap-based buffer overflow to occur. If a remote attacker supplies a vulnerable Apple QuickTime installation with a specially crafted QTIF image, that attacker may be able to trigger the buffer overflow. This issue affects QuickTime installations on both Apple Mac and Microsoft Windows operating systems.

Note that since QuickTime is a component of Apple iTunes, iTunes installations are also affected by this vulnerability.


Impact

A remote unauthenticated attacker may be able to execute arbitrary code or cause a denial-of-service condition, if they can persuade a user to access a specially crafted QTIF image.


Solution

Apply Update
Apple has corrected this issue in Apple Security Update for QuickTime 7.0.4.


Do not access QTIF files from untrusted sources

Exploitation occurs by accessing a specially crafted QTIF file with QuickTime. By only accessing QTIF files from trusted or known sources, the chances of exploitation are reduced.
