-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 ==================================================================== Red Hat Security Advisory Synopsis: Moderate: OpenShift Container Platform 4.7.12 bug fix and security update Advisory ID: RHSA-2021:1561-01 Product: Red Hat OpenShift Enterprise Advisory URL: https://access.redhat.com/errata/RHSA-2021:1561 Issue date: 2021-05-24 CVE Names: CVE-2020-27813 CVE-2020-28362 CVE-2021-3114 CVE-2021-21639 CVE-2021-21640 CVE-2021-28163 CVE-2021-28165 CVE-2021-30465 ==================================================================== 1. Summary: Red Hat OpenShift Container Platform release 4.7.12 is now available with updates to packages and images that fix several bugs. This release includes a security update for Red Hat OpenShift Container Platform 4.7.12. 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. 2. Description: Red Hat OpenShift Container Platform is Red Hat's cloud computing Kubernetes application platform solution designed for on-premise or private cloud deployments. 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. This advisory contains the container images for Red Hat OpenShift Container Platform 4.7.12. See the following advisory for the RPM packages for this release: https://access.redhat.com/errata/RHSA-1562 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: * Previously, the node-exporter daemonset's mountstats collector caused high memory usage on nodes with NFS mount points. By disabling the mountstats collector, this fix reduces memory usage. (BZ#1955469) * A previous change to gophercloud/utils introduced a custom HTTP client that uses a self-signed certificate. But because this change removed settings from DefaultTransport, including those for proxy environment variables, this caused failures for installations that use both self-signed certificates and proxies. In this update, the custom HTTP client inherits settings from DefaultTransport, so now OCP can be installed with self-signed certificates and proxies. (BZ#1943500) * Previously, bare metal deployments failed when large packet transfers between Ironic and the RAM disk resulted in connection failures. In this update, Ironic queries the RAM disk for information to work around the connection error, allowing deployments to succeed.(BZ#1958965) * Previously, when an IPv6 cluster was started on nodes that had IPv4 addresses, kublet sometimes used the nodes' IPv4 IP addresses instead of their IPv6 IP addresses, which prevented host-network pods from reaching IPv6-only pods. This update changes the way node IP addresses are chosen. Now, all nodes have IPv6 addresses. (BZ#1942488) * Previously, OVN changed the source IP addresses of hairpin traffic packets to the IP address of the load balancer, which sometimes blocked traffic when a network policy was in use. With this update, Kuryr opens traffic to the IP addresses of all services in a network policy's namespace, and hairpin traffic flows freely. (BZ#1959766) Security Fix(es): * golang-github-gorilla-websocket: integer overflow leads to denial of service (CVE-2020-27813) 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.
