Descriptions
In FreeRDP less than or equal to 2.1.2, an integer overflow exists due to missing input sanitation in rdpegfx channel. All FreeRDP clients are affected. The input rectangles from the server are not checked against local surface coordinates and blindly accepted. A malicious server can send data that will crash the client later on (invalid length arguments to a `memcpy`) This has been fixed in 2.2.0. As a workaround, stop using command line arguments /gfx, /gfx-h264 and /network:auto
En FreeRDP versiones anteriores o igual a 2.1.2, se presenta un desbordamiento de enteros debido a una falta de saneamiento de entrada en el canal rdpegfx. Todos los clientes de FreeRDP están afectados. Los rectángulos de entrada del servidor no son comprobados contra las coordenadas de la superficie local y se aceptan ciegamente. Un servidor malicioso puede enviar datos que bloquearán al cliente más adelante (argumentos de longitud no válidos a un "memcpy"). Esto ha sido corregido en la versión 2.2.0. Como solución alternativa, deje de usar argumentos de línea de comandos /gfx, /gfx-h264 y /network:auto
