CVE-2011-3252

Desbordamiento de búfer en CoreAudio, como el que se utiliza en iTunes de Apple anterior a v10.5, permite a atacantes remotos ejecutar código arbitrario o causar una denegación de servicio (caída de aplicación) a través de un envío de datos manipulado Advanced Audio Coding (AAC).

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Apple QuickTime Player. Authentication is not required to exploit this vulnerability. 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 how the application parses an audio stream encoded with the advanced audio codec. A field will be read from the file in order to calculate a length that is later used in a memory copy operation into a statically sized buffer. Successful exploitation can lead to code execution under the context of the application.
