-- Vulnerability Details:
This vulnerability allows remote attackers to execute arbitrary code on
vulnerable installations of Apple Quicktime. User interaction is
required in that a user must be coerced into opening up a malicious
document or visiting a malicious website.

The specific flaw exists within the way the application parses a
particular property out of a flashpix file. The application will
explicitly trust a field in the property as a length for a loop over an
array of data structures. If this field's value is larger than the
number of objects, the application will utilize objects outside of this
array. Successful exploitation can lead to code execution under the
context of the application.

-- Vendor Response:
Apple has issued an update to correct this vulnerability. More
details can be found at:
