libcurl would reuse a previously created connection even when a TLS or SSHrelated option had been changed that should have prohibited reuse.libcurl keeps previously used connections in a connection pool for subsequenttransfers to reuse if one of them matches the setup. However, several TLS andSSH settings were left out from the configuration match checks, making themmatch too easily.
libcurl reusaba una conexión creada previamente incluso cuando había sido cambiada una opción relacionada con TLS o SSH que debería haber prohibido el reúso. libcurl mantiene las conexiones usadas previamente en un pool de conexiones para que las transferencias posteriores las reúsen si una de ellas coincide con la configuración. Sin embargo, varias opciones relacionadas con TLS y SSH se dejaron fuera de las comprobaciones de coincidencia de la configuración, lo que hizo que coincidieran con demasiada facilidad
