CVE-2023-39354

Estado: ModificadaAlta (7.5)—

FreeRDP es una implementación gratuita del Protocolo de Escritorio Remoto (RDP), publicado bajo la licencia Apache. Las versiones afectadas están sujetas a una lectura fuera de límites (Out-Of-Bounds Read) en la función 'nsc_rle_decompress_data'. La lectura fuera de límites (Out-Of-Bounds Read) ocurre porque procesa 'context->Planes' sin verificar si contiene datos de longitud suficiente. Si un atacante pudiera aprovechar esta vulnerabilidad, podría causar un fallo. Este problema ha sido solucionado en las versiones 2.11.0 y 3.0.0-beta3. Se aconseja a los usuarios actualizar. No se conocen soluciones alternativas para esta vulnerabilidad.
