Descriptions
In FreeRDP greater than 1.1 and before 2.0.0, there is an out-of-bounds read in update_read_icon_info. It allows reading a attacker-defined amount of client memory (32bit unsigned -> 4GB) to an intermediate buffer. This can be used to crash the client or store information for later retrieval. This has been patched in 2.0.0.
En FreeRDP versiones superiores a 1.2 y versiones anteriores a 2.0.0, se presenta una lectura fuera de límites en update_read_icon_info. Permite leer una cantidad de memoria del cliente definida por el atacante (32 bits sin signo -) 4 GB) en un búfer intermedio. Esto puede ser usado para bloquear el cliente o almacenar información para su posterior recuperación. Esto ha sido parcheado en la versión 2.0.0.
