Descriptions

The qs module before 1.0.0 in Node.js does not call the compact function for array data, which allows remote attackers to cause a denial of service (memory consumption) by using a large index value to create a sparse array.

El módulo qs anterior a 1.0.0 en Node.js no llama a la función 'compact' en la matriz de datos, lo que permite a atacantes remotos causar una denegación de servicio (consumo de memoria) usando un valor largo del index para crear una matriz dispersa.

The nodejs-qs module has the ability to create sparse arrays during parsing. By specifying a high index in a querystring parameter it is possible to create a large array that will eventually take up all the allocated memory of the running process, resulting in a crash.

Node.js is a software development platform for building fast and scalable network applications in the JavaScript programming language. Security Fix: The nodejs-qs module has the ability to create sparse arrays during parsing. By specifying a high index in a querystring parameter it is possible to create a large array that will eventually take up all the allocated memory of the running process, resulting in a crash.
