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.

The specific flaw exists within the parsing of invalid data in the mdat atom. An attacker can use this flaw to read outside the

allocated buffer, which could allow for the execution of arbitrary code in the context of the current process.
