M Alto vulnerabilidad

Vulnerabilidad de denegación de servicio en FreeRDP anterior a versión 3.29.0

FreeRDP versiones anteriores a 3.29.0 contiene una vulnerabilidad de denegación de servicio (DoS) en el manejador del canal RDPEI que no valida la longitud máxima del cuerpo PDU antes de asignar memoria. Un cliente RDP malicioso puede enviar un mensaje RDPEI solo con encabezado y una longitud de cuerpo declarada grande, forzando asignación excesiva de memoria en el servidor. Empresas en LATAM que utilizan FreeRDP en infraestructuras de acceso remoto deben actualizar inmediatamente para evitar interrupciones de servicios altas.
