Created undertow tracking bugs for this issue:

Affects: fedora-all [bug 1748604]

Comment 40 Sam Fowler 2019-09-04 07:06:56 UTC

Statement:

This issue affects the version of grafana(embeds gRPC) as shipped with Red Hat Ceph Storage 3 as it include the support for HTTP/2.
This flaw has no available mitigation for nodejs package. It will be updated once the available fixes are released for Red Hat Enterprise Linux and Red Hat Software Collections.

The nodejs RPM shipped in OpenShift Container Platform 3.9 and 3.10 is not affected by this flaw as it does not contain the vulnerable code.
