Una vulnerabilidad de desbordamiento aritmético por defecto de entero (Integer Underflow, Wrap o Wraparound) en el proceso rpd de Juniper Networks Junos OS en las series EX y MX, y en Junos OS Evolved en la serie ACX, permite a un atacante adyacente no autenticado provocar la divulgación de memoria dinámica (heap) y la inyección de estados de unión multidifusión (multicast join-state) mediante un mensaje Rosen-MVPN malformado.

Este problema solo afecta a las plataformas que admiten el borrador de Rosen MVPN, como las series ACX, EX y MX.
