Descriptions

In FreeRDP less than or equal to 2.0.0, when using a manipulated server with USB redirection enabled (nearly) arbitrary memory can be read and written due to integer overflows in length checks. This has been patched in 2.1.0.

En FreeRDP versiones anteriores o iguales a 2.0.0, cuando se usa un servidor manipulado con redirección del USB permitió que (por poco) una memoria arbitraria pueda ser leída y escrita debido a unos desbordamientos de enteros en las comprobaciones de longitud. Esto ha sido parcheado en la versión 2.1.0.
