CVE-2011-2120

Desbordamiento de enteros en el componente CursorAsset x32 de Adobe Shockwave Player en versiones anteriores a v11.6.0.626 permite a los atacantes ejecutar código arbitrario a través de vectores no especificados.

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of the Adobe Shockwave 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 Cursor Asset.x32 module responsible for parsing cursor structures from within Director movie files (.dir). While handling a size element, the code performs an unchecked multiplication operation which can cause an integer to wrap. This results in an undersized heap allocation which can be overflowed with user data leading to arbitrary code execution under the context of the user running the browser.
