CVE-2010-4190

Adobe Shockwave Player en versiones anteriores a la 11.5.9.620 permite que los atacantes ejecuten código arbitrario o provoquen una denegación de servicio (corrupción de memoria) mediante una película Director con un fragmento RIFF CSWV que provoca un cálculo incorrecto de un desplazamiento para una subestructura, lo que provoca un "seek" fuera de límites de la memoria dinámica (heap). Esta vulnerabilidad es diferente de CVE-2011-0555, CVE-2010-4093, CVE-2010-4187, CVE-2010-4191, CVE-2010-4192 y CVE-2010-4306.

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 code responsible for parsing substructures referenced by the CSWV RIFF chunk. An offset is improperly calculated from several elements of a substructure. By crafting a director file in a particular way, an attacker can cause the process to seek out of the bounds of a heap allocation. Due to the way the process continues to manipulate memory, an attacker can force reliable corruption that can be leveraged to execute arbitrary code under the context of the user running the browser.
