      "value": "cumulative-distribution-function is an open source npm library used which calculates statistical cumulative distribution function from data array of x values. In versions prior to 2.0.0 apps using this library on improper data may crash or go into an infinite-loop. In the case of a nodejs server-app using this library to act on invalid non-numeric data, the nodejs server may crash. This may affect other users of this server and/or require the server to be rebooted for proper operation. In the case of a browser app using this library to act on invalid non-numeric data, that browser may crash or lock up. A flaw enabling an infinite-loop was discovered in the code for evaluating the cumulative-distribution-function of input data. Although the documentation explains that numeric data is required, some users may confuse an array of strings like [\"1\",\"2\",\"3\",\"4\",\"5\"] for numeric data [1,2,3,4,5] when it is in fact string data. An infinite loop is possible when the cumulative-distribution-function is evaluated for a given point when the input data is string data rather than type `number`. This vulnerability enables an infinite-cpu-loop denial-of-service-attack on any app using npm:cumulative-distribution-function v1.0.3 or earlier if the attacker can supply malformed data to the library. The vulnerability could also manifest if a data source to be analyzed changes data type from Arrays of number (proper) to Arrays of string (invalid, but undetected by earlier version of the library). Users should upgrade to at least v2.0.0, or the latest version. Tests for several types of invalid data have been created, and version 2.0.0 has been tested to reject this invalid data by throwing a `TypeError()` instead of processing it. Developers using this library may wish to adjust their app's code slightly to better tolerate or handle this TypeError. Apps performing proper numeric data validation before sending data to this library should be mostly unaffected by this patch. The vulnerability can be mitigated in older versions by ensuring that only finite numeric data of type `Array[number]` or `number` is passed to `cumulative-distribution-function` and its `f(x)` function, respectively."

      "value": "cumulative-distribution-function es una biblioteca npm de código abierto usada que calcula la función statistical cumulative distribution a partir de una matriz de datos de valores x. En versiones anteriores a la 2.0.0, las aplicaciones que utilizan esta biblioteca con datos malformados pueden presentar un fallo o entrar en un bucle infinito. En el caso de una aplicación de servidor de nodejs que use esta biblioteca para actuar sobre datos no numéricos no válidos, el servidor de nodejs puede bloquearse. Esto puede afectar a otros usuarios de este servidor y/o requerir que el servidor sea reiniciado para que funcione apropiadamente. En el caso de una aplicación de navegador que utilice esta biblioteca para actuar sobre datos no numéricos no válidos, ese navegador puede bloquearse o suspenderse. Se detectó un fallo que permite un bucle infinito en el código para evaluar la cumulative-distribution-function de los datos de la entrada. Aunque la documentación explica que se requieren datos numéricos, algunos usuarios pueden confundir una matriz de cadenas como [\"1\",\"2\",\"3\",\"4\",\"5\"] para datos numéricos [1,2,3,4,5] cuando es en efecto una cadena de datos. Un bucle infinito es posible cuando la cumulative-distribution-function es evaluada para un punto específico cuando el dato de la entrada es una cadena de datos en vez de un tipo “number”. Esta vulnerabilidad habilita un ataque de denegación de servicio en el bucle cpu infinito en cualquier aplicación que utilice npm: cumulative-distribution-function versiones v1.0.3 o anteriores si el atacante puede suministrar datos malformados a la biblioteca. La vulnerabilidad también podría manifestarse si una fuente de datos a analizar cambia el tipo de datos de Matrices de números (propiamente dichos) a Matrices de cadenas (no válidas, pero no detectadas por una versión anterior de la biblioteca). Los usuarios deben actualizar al menos a la versión v2.0.0 o la última versión. Se han creado pruebas para varios tipos de datos no válidos, y se ha probado la versión 2.0.0 para rechazar estos datos no válidos lanzando un “Typebug()” en lugar de procesarlos. Los desarrolladores que utilizan esta biblioteca pueden desear ajustar ligeramente el código de su aplicación para tolerar o manejar mejor este Typebug. Las aplicaciones que llevan a cabo una comprobación de datos numérica apropiada antes de enviar datos a esta biblioteca no deberían estar afectadas en su mayoría por este parche. La vulnerabilidad puede ser mitigada en versiones anteriores asegurándose de que solo se pasen datos numéricos finitos de tipo “Array[number]” o “number” a la \"cumulative-distribution-function\" y su función f(x), respectivamente."
