CVE-2010-2871

Desbordamiento de entero en la funcionalidad 3D en Adobe Shockwave Player anterior a 11.5.8.612, permite a atacantes remotos provocar una denegación de servicio (corrupción de memoria dinámica -heap-) o la ejecución de código de su elección a través de un tamaño con un valor manipulado en un registro 0xFFFFFF45 RIFF en una película de Director.

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 application's support for 3D objects. While parsing the 0xFFFFFF45 RIFF record type, the process performs arithmetic on a size value and uses the result for a heap-based allocation. By specifying a large enough value an attacker can force the integer to wrap and thus the process will under-allocate the buffer. This memory is later copied into using a different size value which results in object corruption that can be leveraged to execute arbitrary code under the context of the user running the browser.
