Descriptions
In FreeRDP after 1.1 and before 2.0.0, there is an out-of-bounds read in autodetect_recv_bandwidth_measure_results. A malicious server can extract up to 8 bytes of client memory with a manipulated message by providing a short input and reading the measurement result data. This has been patched in 2.0.0.
En FreeRDP versiones posteriores a 1.1 y versiones anteriores a 2.0.0, se presenta una lectura fuera de límites en autodetect_recv_bandwidth_measure_results. Un servidor malicioso puede extraer hasta 8 bytes de la memoria del cliente con un mensaje manipulado al proporcionar una entrada corta y leer los datos del resultado de la medición. Esto ha sido parcheado en la versión 2.0.0.
