Apple QuickTime Player H.264 Codec contains an integer overflow

Overview

Apple QuickTime fails to properly handle H.264 movies. This vulnerability may allow a remote, unauthenticated attacker to execute arbitrary code or cause a denial-of-service condition.

I. Description

Apple QuickTime Player is multimedia software that allows users to view local and remote audio, video, and image content. According to Apple:

    By carefully crafting a corrupt H.264 movie, an attacker can trigger an integer overflow or buffer overflow which may lead to an application crash or arbitrary code execution with the privileges of the user.

This vulnerability may be triggered by sending QuickTime Player, or an application that uses the QuickTime plug-in, a specially crafted H.264 movie.

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

II. Impact

A remote, unauthenticated attacker may be able to execute arbitrary code or cause a denial of service condition.

III. Solution

Upgrade QuickTime

Apple has addressed this issue with QuickTime 7.1.3 as specified in Apple Support Document 304357.

Disable QuickTime in your web browser

An attacker may be able to exploit this vulnerability by persuading a user to access a specially crafted file with a web browser. Disabling QuickTime in your web browser will defend against this attack vector. For more information, refer to the Securing Your Web Browser document.
