      "value": "A read buffer overrun can be triggered in X.509 certificate verification,\nspecifically in name constraint checking. Note that this occurs\nafter certificate chain signature verification and requires either a\nCA to have signed the malicious certificate or for the application to\ncontinue certificate verification despite failure to construct a path\nto a trusted issuer.\n\nThe read buffer overrun might result in a crash which could lead to\na denial of service attack. In theory it could also result in the disclosure\nof private memory contents (such as private keys, or sensitive plaintext)\nalthough we are not aware of any working exploit leading to memory\ncontents disclosure as of the time of release of this advisory.\n\nIn a TLS client, this can be triggered by connecting to a malicious\nserver. In a TLS server, this can be triggered if the server requests\nclient authentication and a malicious client connects.\n\n"

      "value": "Un desbordamiento del b\u00fafer de lectura puede activarse en la verificaci\u00f3n de certificados X.509, espec\u00edficamente en la verificaci\u00f3n de restricciones de nombre. Tenga en cuenta que esto ocurre despu\u00e9s de la verificaci\u00f3n de la firma de la cadena de certificados y requiere que una CA haya firmado el certificado malicioso o que la aplicaci\u00f3n contin\u00fae con la verificaci\u00f3n del certificado a pesar de no poder construir una ruta a un emisor de confianza. El desbordamiento del b\u00fafer de lectura puede provocar un bloqueo que podr\u00eda conducir a un ataque de denegaci\u00f3n de servicio. En teor\u00eda, tambi\u00e9n podr\u00eda provocar la divulgaci\u00f3n de contenidos de memoria privada (como claves privadas o texto plano confidencial), aunque no conocemos ning\u00fan exploit en funcionamiento que conduzca a la divulgaci\u00f3n de contenidos de memoria al momento de la publicaci\u00f3n de este aviso. En un cliente TLS, esto puede activarse al conectarse a un servidor malicioso. En un servidor TLS, esto puede activarse si el servidor solicita la autenticaci\u00f3n del cliente y un cliente malicioso se conecta."
