-- Vulnerability 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 open a
malicious file.

The specific flaw exists in the handling of movie data encoded using the
Cinepak Video Codec. When parsing the data in the MDAT atom, there
exists a signedness error which leads to a heap overflow. When this
occurs it can be further leveraged to execute arbitrary code under the
context of the current user.
