Apple QuickTime vulnerable to denial of service via specially crafted FlashPix file

Overview

A buffer overflow vulnerability in the way Apple QuickTime handles FlashPix files could allow a remote attacker to execute arbitrary code or cause a denial-of-service condition.

Description

A buffer overflow vulnerability in QuickTime for Windows and Mac OS X 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 FlashPix file, an attacker can trigger the overflow.

Depending on settings, a web browser could automatically open a FlashPix file with QuickTime. Apple iTunes includes QuickTime.
