Comment 1 Laura Pardo 2018-12-19 19:49:26 UTC

Created nodejs tracking bugs for this issue:

Affects: epel-all [bug 1661007]
Affects: fedora-all [bug 1661006]

Comment 2 Cedric Buissart 2019-01-15 17:05:33 UTC

Quick correction on nodejs 6 : the commit 5d9005c35 is also required. The fixed version is actually 6.15.1

Comment 8 Sam Fowler 2019-06-13 05:16:17 UTC

Statement:

The nodejs RPMs shipped in Red Hat OpenShift Container Platform (OCP) versions 3.6 through 3.10 are vulnerable to this flaw because they contain the affected code. Later versions of OCP used nodejs RPMs delivered from Red Hat Software Collections and Red Hat Enterprise Linux channels.

Comment 11 Cedric Buissart 2019-06-19 09:20:12 UTC

Mitigation:

The use of a Load Balancer or a Reverse Proxy will increase the difficulty of the attack.
