The remote Redhat Enterprise Linux 7 / 8 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2021:0958 advisory.
Red Hat OpenShift Container Platform is Red Hat's cloud computing Kubernetes application platform solution designed for on-premise or private cloud deployments.
This advisory contains the RPM packages for Red Hat OpenShift Container Platform 4.7.4. See the following advisory for the container images for this release:
https://access.redhat.com/errata/RHSA-2021:0957
All OpenShift Container Platform 4.7 users are advised to upgrade to these updated packages and images when they are available in the appropriate release channel. To check for available updates, use the OpenShift Console or the CLI oc command. Instructions for upgrading a cluster are available at https://docs.openshift.com/container-platform/4.7/updating/updating-cluster
-between-minor.html#understanding-upgrade-channels_updating-cluster-between
-minor.
Security Fix(es):
* golang: crypto/elliptic: incorrect operations on the P-224 curve (CVE-2021-3114)
For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
