Descriptions
A use-after-free vulnerability was discovered in Adobe Flash Player before 28.0.0.161. This vulnerability occurs due to a dangling pointer in the Primetime SDK related to media player's quality of service functionality. A successful attack can lead to arbitrary code execution.
Se ha descubierto una vulnerabilidad de uso de memoria previamente liberada en Adobe Flash Player, en versiones anteriores a la 28.0.0.161. Esta vulnerabilidad ocurre debido a un puntero pendiente en el SDK Primetime relacionado con la funcionalidad de calidad del servicio del media player. Un ataque con éxito podría permitir la ejecución arbitraria de código.
This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Adobe Flash. 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 handling of QOSProvider objects. The issue results from the lack of validating the existence of an object prior to performing operations on the object. An attacker can leverage this vulnerability to execute code under the context of the current process.
