SnappyFrameDecoder doesn't restrict chunk length and may buffer skippable chunks in an unnecessary way
CVE: CVE-2021-37137
Component: netty-codec
CWE: CWE-400
Severity: Moderate
CVSS v3: 7.5/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
Release date: 2021-09-09T00:00:00+00:00

A flaw was found in the Netty's netty-codec due to unrestricted chunk lengths in the SnappyFrameDecoder. By sending a specially-crafted input, a remote attacker could cause excessive memory usage resulting in a denial of service.

Statement: In OpenShift Container Platform (OCP), the Hive/Presto/Hadoop components that comprise the OCP Metering stack, ship the vulnerable version of netty-codec package.
Since the release of OCP 4.6, the Metering product has been deprecated [1], hence the affected components are marked as wontfix.
This may be fixed in the future.

Starting in OCP 4.7, the elasticsearch component is shipping as a part of the OpenShift Logging product (openshift-logging/elasticsearch6-rhel8). The elasticsearch component delivered in OCP 4.6 is marked as `Out of support scope` because these versions are already under Maintenance Phase of the support.
