      "value": "In OpenSSL 1.1.0 before 1.1.0c, applications parsing invalid CMS structures can crash with a NULL pointer dereference. This is caused by a bug in the handling of the ASN.1 CHOICE type in OpenSSL 1.1.0 which can result in a NULL value being passed to the structure callback if an attempt is made to free certain invalid encodings. Only CHOICE structures using a callback which do not handle NULL value are affected."

      "value": "En OpenSSL 1.1.0 anterior a 1.1.0c, las aplicaciones que analizan estructuras CMS inv\u00e1lidas pueden dejar de dar servicio por una referencia a puntero nulo. Esto se produce por un fallo en la gesti\u00f3n del tipo ASN.1 CHOICE en OpenSSL 1.1.0, lo que puede derivar en que un valor NULL sea enviado a la devoluci\u00f3n de la llamada si se intenta utilizar varias codificaciones inv\u00e1lidas. S\u00f3lo est\u00e1n afectadas estructuras CHOICE que utilicen una devoluci\u00f3n de llamada que no gestione valores NULL."
