      "value": "FreeRDP is a free implementation of the Remote Desktop Protocol. Versions on the 2.x branch prior to to 2.11.8 and on the 3.x branch prior to 3.23.0 have an out-of-bounds read vulnerability in the FreeRDP client's RDPGFX channel that allows a malicious RDP server to read uninitialized heap memory by sending a crafted WIRE_TO_SURFACE_2 PDU with a `bitmapDataLength` value larger than the actual data in the packet. This can lead to information disclosure or client crashes when a user connects to a malicious server. Versions 2.11.8 and 3.23.0 fix the issue."

      "value": "FreeRDP es una implementación gratuita del Protocolo de Escritorio Remoto. Las versiones de la rama 2.x anteriores a la 2.11.8 y de la rama 3.x anteriores a la 3.23.0 tienen una vulnerabilidad de lectura fuera de límites en el canal RDPGFX del cliente FreeRDP que permite a un servidor RDP malicioso leer memoria de pila no inicializada al enviar una PDU WIRE_TO_SURFACE_2 manipulada con un valor 'bitmapDataLength' mayor que los datos reales en el paquete. Esto puede llevar a la revelación de información o a fallos del cliente cuando un usuario se conecta a un servidor malicioso. Las versiones 2.11.8 y 3.23.0 corrigen el problema."
