      "value": "A flaw was found in python-cryptography versions between >=1.9.0 and <2.3. The finalize_with_tag API did not enforce a minimum tag length. If a user did not validate the input length prior to passing it to finalize_with_tag an attacker could craft an invalid payload with a shortened tag (e.g. 1 byte) such that they would have a 1 in 256 chance of passing the MAC check. GCM tag forgeries can cause key leakage."

      "value": "Se ha encontrado un error en python-cryptography, desde la versi\u00f3n 1.9.0 hasta la 2.3. La API finalize_with_tag no forzaba una longitud de etiqueta m\u00ednima. Si un usuario no validaba la longitud de la entrada antes de pasarla a finalize_with_tag, un atacante podr\u00eda manipular una carga \u00fatil no v\u00e1lida con una etiqueta acortada (p.ej., 1 byte) para as\u00ed tener 1 posibilidad entre 256 de pasar la comprobaci\u00f3n MAC. Las falsificaciones de etiquetas GCM pueden provocar un filtrado de claves."
