-- Vulnerability Details:

This vulnerability allows attackers to execute arbitrary code on

vulnerable installations of Apple QuickTime Player. 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 quicktime.qts library. The

vulnerability resides in the component's parsing of 'crgn' atoms. A lack

of proper sanity checks on the region size field can result in a heap

based buffer overflow leading to arbitrary code execution under the

context of the currently logged in user.
