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.

There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - 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. (CVE-2014-7191)

The 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.
