Descriptions

The Java Management Extensions (JMX) implementation in Sun Java SE 6 before Update 15, and OpenJDK, does not properly enforce OpenType checks, which allows context-dependent attackers to bypass intended access restrictions by leveraging finalizer resurrection to obtain a reference to a privileged object.

La implementación de Java Management Extensions (JMX) en Sun Java SE v6 anteriores a Update 15, y en OpenJDK, no refuerza adecuadamente las validaciones OpenType, permitiendo a los atacantes dependientes del contexto saltar las restricciones de acceso previstas al aprovechar la re-ejecución de un método finalizador para obtener una referencia a un objeto privilegiado.
