3. Description:

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)

described in this advisory, refer to:
