A 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. Version 7.4.1 is affected.
