Red Hat Security Advisory 2017-2672-01

Red Hat Security Advisory 2017-2672-01
Posted Sep 8, 2017
Authored by Red Hat | Site access.redhat.com

Red Hat Security Advisory 2017-2672-01 - The qs module for Node.js is a querystring parser that supports nesting and arrays with a depth limit. The following packages have been upgraded to a later upstream version: rh-nodejs6-nodejs-qs. Security Fix: It was found that ljharb's qs module for Node.js did not properly parse query strings. An attacker could send a specially crafted query that overwrites the resulting object's prototype properties or hasOwnProperty()), resulting in a denial of service when the overwritten function would be executed.
