El desbordamiento de enteros en Adobe Flash Player versión 9.0.115.0 y versiones anteriores, y versión 8.0.39.0 y versiones anteriores, permite que los atacantes remotos ejecuten código arbitrario por medio de un archivo SWF creado con un valor de Scene Count negativo, que pasa por una comparación firmada, se utiliza como compensación de un puntero NULL, y se desencadena un desbordamiento de búfer.

TippingPoint Note: This issue was originally disclosed on April 8, 2008 as ZDI-08-022 but due to an error on our behalf the original advisory was clobbered and is now being re-released as ZDI-08-032.
This vulnerability allows attackers to execute arbitrary code on vulnerable installations of the Adobe Flash 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 DLL responsible for parsing SWF tags. The vulnerable function trusts an offset present within the vulnerable tag and performs memory operations accordingly. By specifying certain values, an attacker is able to control a memory write leading to arbitrary code execution under the context of the currently logged in user.
