TITLE

Windows  and  Linux  for  Intel(R) Graphics Drivers  Integer overflow vulnerability in

DESCRIPTION

Integer overflow in the firmware for some Intel(R) Graphics Drivers for Windows * before version 26.20.100.7212 and before Linux kernel version 5.5 may allow a privileged user to potentially enable an escalation of privilege via local access. There is a security vulnerability in Intel Graphics Drivers. There is no information about this vulnerability at present. Please pay attention to CNNVD or manufacturer announcements at any time. 8) - aarch64, noarch, ppc64le, s390x, x86_64 3. Description: 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 4.7.13. See the following advisory for the RPM packages for this release: https://access.redhat.com/errata/RHSA-2021:2122 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 bug among others: * Previously, resources for the ClusterOperator were being created early in the update process, which led to update failures when the ClusterOperator had no status condition while Operators were updating. This bug fix changes the timing of when these resources are created. As a result, updates can take place without errors. (BZ#1959238) Security Fix(es): * gogo/protobuf: plugin/unmarshal/unmarshal.go lacks certain index validation (CVE-2021-3121) You may download the oc tool and use it to inspect release image metadata as follows: (For x86_64 architecture) $ oc adm release info quay.io/openshift-release-dev/ocp-release:4.7.13-x86_64 The image digest is sha256:783a2c963f35ccab38e82e6a8c7fa954c3a4551e07d2f43c06098828dd986ed4 (For s390x architecture) $ oc adm release info quay.io/openshift-release-dev/ocp-release:4.7.13-s390x The image digest is sha256:4cf44e68413acad063203e1ee8982fd01d8b9c1f8643a5b31cd7ff341b3199cd (For ppc64le architecture) $ oc adm release info quay.io/openshift-release-dev/ocp-release:4.7.13-ppc64le The image digest is sha256:d47ce972f87f14f1f3c5d50428d2255d1256dae3f45c938ace88547478643e36 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 3. Solution: For OpenShift Container Platform 4.7 see the following documentation, which will be updated shortly for this release, for important instructions on how to upgrade your cluster and fully apply this asynchronous errata update: https://docs.openshift.com/container-platform/4.7/release_notes/ocp-4-7-rel ease-notes.html Details on how to access this content are available at https://docs.openshift.com/container-platform/4.7/updating/updating-cluster - -cli.html 4.
