CVE-2020-24659

Se detectó un problema en GnuTLS versiones anteriores a 3.6.15. Un servidor puede desencadenar una desreferencia del puntero NULL en un cliente TLS versión 1.3, si una alerta no_renegotiation es enviada con una sincronización no prevista y luego se produce un segundo protocolo de enlace no válido. El bloqueo ocurre en la ruta de manejo de errores de la aplicación, donde la función gnutls_deinit es llamada después de detectar un fallo en el protocolo de enlace
