libcurl did not check the server certificate of TLS connections done to a host specified as an IP address, when built to use mbedTLS. libcurl would wrongly avoid using the set hostname function when the specified hostname was given as an IP address, therefore completely skipping the certificate check. This affects all uses of TLS protocols (HTTPS, FTPS, IMAPS, POPS3, SMTPS, etc).
libcurl no verificó el certificado del servidor de las conexiones TLS realizadas a un host especificado como dirección IP, cuando se creó para usar mbedTLS. libcurl evitaría erróneamente el uso de la función establecer nombre de host cuando el nombre de host especificado se proporcionara como dirección IP, por lo que se saltaría por completo la verificación del certificado. Esto afecta a todos los usos de los protocolos TLS (HTTPS, FTPS, IMAPS, POPS3, SMTPS, etc).
