FreeRDP es una librería de protocolos de escritorio remoto gratuitos y clientes. Las versiones afectadas de FreeRDP pueden intentar sumar números enteros en tipos demasiado estrechos, lo que lleva a la asignación de un búfer demasiado pequeño que contiene los datos escritos. Un servidor malicioso puede engañar a un cliente basado en FreeRDP para que lea datos fuera de enlace y los envíe de vuelta al servidor. Este problema se solucionó en la versión 2.9.0 y se recomienda a todos los usuarios que actualicen. Los usuarios que no puedan actualizar no deben usar el interruptor de redirección `/usb`.
