CVE-2023-40567

Estado: ModificadaCrítica (9.8)—

FreeRDP es una implementación gratuita del Protocolo de Escritorio Remoto (RDP), publicado bajo la licencia Apache. Las versiones afectadas están sujetas a una escritura fuera de límites (Out-Of-Bounds Write) en la función 'clear_decompress_bands_data' en la que no hay validación de desplazamiento. El abuso de esta vulnerabilidad puede conducir a una escritura fuera de límites. Este problema ha sido solucionado en las versiones 2.11.0 y 3.0.0-beta3. Se recomienda a los usuarios actualizar. No existen soluciones alternativas conocidas para esta vulnerabilidad.
