3) Technical details
============================

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Apple QuickTime.
User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.

By providing a malformed FPX file, an attacker is able to create controlled memory corruption, and execute code in the context of the current user.
