Summary

Node.js is a software development platform for building fast and scalable network applications in the JavaScript programming language.
The following packages have been upgraded to a later upstream version: rh-nodejs6-nodejs (6.11.3). (BZ#1476317)
Security Fix(es):
* It was found that Node.js was using a non-randomized seed when populating hash tables. An attacker, able to supply a large number of inputs, could send specially crafted entries to the Node.js application, maximizing hash collisions to trigger an excessive amount of CPU usage, resulting in a denial of service. (CVE-2017-11499)
