Vulnerability Note VU#448745

Apple QuickTime PICT heap buffer overflow

Original Release date: 06 Mar 2007 | Last revised: 09 Mar 2007

Overview

The 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.

Description

PICT is a graphics file format that was used by Apple Macintosh systems prior to OS X as their standard metafile format. OS X systems can open and display PICT files.

Apple 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 PICT file with QuickTime, an attacker can trigger the overflow.

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.

Impact

A remote, unauthenticated attacker can execute arbitrary code or create a denial-of-service condition. The crafted QuickTime PICT 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.

Solution

Update
Apple has released QuickTime 7.5 to address this issue.
