Apple QuickTime image handling buffer overflow

Vulnerability Note VU#629845

Original Release Date: 2006-01-11 | Last Revised: 2006-01-13

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. In addition, this issue may also be exploitable via specially crafted PICT and JPEG images.

Note that this issue affects QuickTime installations on both Apple Mac and Microsoft Windows operating systems.

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. This update is also included in the Mac OS X 10.4.4 Update (Delta).

Do not access Image files from untrusted sources


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