--- Comment #3 from Jason Shepherd jshepherd@redhat.com --- Statement:
OpenShift Container Platform ships a vulnerable netty library as part of the logging-elasticsearch5 container. ElasticSearch's security team has stated that the previous vulnerability, CVE-2019-16869, does not poses a substantial practical threat to ElasticSearch 6 [1]. We agree that this issue would be difficult to exploit both these vulnerabilities on OpenShift Container Platform, so we're reducing the impact of this issue to moderate and may fix it in the future release.

--- Doc Text *updated* by Jonathan Christison jochrist@redhat.com --- It was found Netty before 4.1.44 was found to accept multiple `Content-Length` headers and also accepted `Transfer-Encoding` as well as `Content-Length` headers where it should reject the message under such circumstances.
In circumstances where Netty is used in the context of a server it could result in a viable http smuggling vulnerability.

Red Hat Satellite ships a vulnerable version of netty embedded in Candlepin. However, the flaw can not be triggered in that context, because HTTP requests are handled by Tomcat, not by netty. A future release may fix this.

--- Comment #35 from Jonathan Christison jochrist@redhat.com --- Marking Red Hat Jboss Fuse 6 as having a moderate impact, Fuse 6 distributes affected versions of Netty, however its use in Fuse 6 fabric-gateway is not susceptible to the vulnerability as the fabric-gateway will create a new http client upon each gateway invocation, this means there is no multiplexing of connections, this is a prerequisite of HTTP smuggling/desynchronisation attacks.
This vulnerability is out of security support scope for the following products: * Red Hat JBoss Fuse 6
