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.
