Summary

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.

    descriptionThe qs module has the ability to create sparse arrays during parsing. By specifying a high index 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. More information: https://github.com/visionmedia/node-querystring/issues/104 Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
