CVE-2018-21029

systemd 239 through 245 accepts any certificate signed by a trusted certificate authority for DNS Over TLS. Server Name Indication (SNI) is not sent, and there is no hostname validation with the GnuTLS backend. NOTE: This has been disputed by the developer as not a vulnerability since hostname validation does not have anything to do with this issue (i.e. there is no hostname to be sent)

** EN DISPUTA ** systemd versiones 239 hasta la versión 245, acepta cualquier certificado firmado por parte de una autoridad de certificación de confianza para DNS Over TLS. La indicación de nombre de servidor (SNI) no se envía y no existe comprobación de nombre de host con el backend GnuTLS. NOTA: Esto ha sido discutido por el desarrollador como una vulnerabilidad, ya que la validación del hostname no tiene nada que ver con este problema (es decir, no hay ningún nombre de host que se envíe)
