"An update for nodejs-tough-cookie and nodejs is now available for Red
Hat OpenShift Container Platform 3.1, 3.2, and 3.3.

Red Hat Product Security has rated this update as having a security
impact of Moderate. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available for each
vulnerability from the CVE link(s) in the References section.

Red Hat OpenShift Container Platform is the company's cloud computing
Platform-as-a-Service (PaaS) solution designed for on-premise or
private cloud deployments.

Security Fix(es) :

* A regular expression denial of service flaw was found in
Tough-Cookie. An attacker able to make an application using
Touch-Cookie to parse a sufficiently large HTTP request Cookie header
could cause the application to consume an excessive amount of CPU.
(CVE-2016-1000232)

* It was found that the reason argument in ServerResponse#writeHead()
was not properly validated. A remote attacker could possibly use this
flaw to conduct an HTTP response splitting attack via a specially
crafted HTTP request. (CVE-2016-5325)
