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 PSD file, an attacker is able to create an out of bound read condition and execute code in the context of the current user or may allow access to sensitive memory space.
