CVE-2011-0557

Un desbordamiento de enteros en Shockwave Player de Adobe anterior a versión 11.5.9.620, permite a los atacantes remotos ejecutar código arbitrario por medio de una película Director con un gran valor de conteo en el registro de activos 3D tipo 0xFFFFFF45, que desencadena un "faulty allocation" y la corrupción de memoria.

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 parsing of 3D assets within a director movie. The routine responsible for parsing 3D record type 0xFFFFFF45 does not properly validate a count field within the structure. If this value is too large, the process can create a faulty allocation. Later, when the rendering routine attempts to use this buffer memory is corrupted. This can be abused by remote attackers to execute arbitrary code under the context of the user running the browser.
