CVE-2012-0669

Desbordamiento de búfer en Apple QuickTime antes de 7.7.2 en Windows que permite a atacantes remotos ejecutar código arbitrario o causar una denegación de servicio (caída de aplicación) a través de un archivo de película modificado que tenga codificación Sorenson.

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Apple QuickTime. 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 way Apple QuickTime handles file with the Sorenson v3 Codec. When parsing the data inside the svq3 stream QuickTime does not verify the value for the mb_skip_run value it reads from the data. This value is used later as a loop counter to write data to a heap allocation without boundary checking. This can result in a heap based buffer overflow that can result in remote code execution under the context of the user running the application.
