===================================================================== Red Hat Security Advisory
Synopsis: Moderate: OpenShift Container Platform 4.7.4 security update Advisory ID: RHSA-2021:0957-01 Product: Red Hat OpenShift Enterprise Advisory URL: https://access.redhat.com/errata/RHSA-2021:0957 Issue date: 2021-03-30 CVE Names: CVE-2020-27827 CVE-2020-35498 CVE-2021-3114 =====================================================================
- Summary:
Red Hat OpenShift Container Platform release 4.7.4 is now available with updates to packages and images that fix several bugs and add enhancements.
Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
- Description:
Red Hat OpenShift Container Platform is Red Hat's cloud computing Kubernetes application platform solution designed for on-premise or private cloud deployments.
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 container images for Red Hat OpenShift Container Platform 4.7.4. See the following advisory for the RPM packages for this release:
https://access.redhat.com/errata/RHSA-2021:0958
Space precludes documenting all of the container images in this advisory. See the following Release Notes documentation, which will be updated shortly for this release, for details about these changes:
https://docs.openshift.com/container-platform/4.7/release_notes/ocp-4-7-rel ease-notes.html
This update fixes the following bugs among others:
-
A flaw was found in golang: crypto/elliptic, in which P-224 keys as generated could return incorrect inputs, which reduced the strength of the cryptography. (BZ#1918750)
-
This update adds new capabilities to the Baremetal Operator, allowing for different reboot modes to be utilized. This allows workloads to be relocated as quickly as possible in the event of a node failure. Additionally, it provides a path for clients to quickly power down systems for remediation purposes and to recover workloads. As a result, workload recovery time is significantly reduced. (BZ#1936407)

Summary:\n\nRed Hat OpenShift Container Platform release 4.7.4 is now available with\nupdates to packages and images that fix several bugs and add enhancements. \n\nRed Hat Product Security has rated this update as having a security impact\nof Moderate. A Common Vulnerability Scoring System (CVSS) base score, which\ngives a detailed severity rating, is available for each vulnerability from\nthe CVE link(s) in the References section. \n\n2.

See the following advisory for the RPM packages for this\nrelease:\n\nhttps://access.redhat.com/errata/RHSA-2021:0958\n\nSpace precludes documenting all of the container images in this advisory. \nSee the following Release Notes documentation, which will be updated\nshortly for this release, for details about these changes:\n\nhttps://docs.openshift.com/container-platform/4.7/release_notes/ocp-4-7-rel\nease-notes.html\n\nThis update fixes the following bugs among others:\n\n* A flaw was found in golang: crypto/elliptic, in which P-224 keys as\ngenerated could return incorrect inputs, which reduced the strength of the\ncryptography. (BZ#1918750)\n\n* This update adds new capabilities to the Baremetal Operator, allowing for\ndifferent reboot modes to be utilized. This allows workloads to be\nrelocated as quickly as possible in the event of a node failure. \nAdditionally, it provides a path for clients to quickly power down systems\nfor remediation purposes and to recover workloads. As a result, workload\nrecovery time is significantly reduced.
