TITLE

curl  Vulnerability in resource initialization deficiency in

DESCRIPTION

curl 7.7 through 7.76.1 suffers from an information disclosure when the `-t` command line option, known as `CURLOPT_TELNETOPTIONS` in libcurl, is used to send variable=content pairs to TELNET servers. Due to a flaw in the option parser for sending NEW_ENV variables, libcurl could be made to pass on uninitialized data from a stack based buffer to the server, resulting in potentially revealing sensitive internal information to the server using a clear-text network protocol. curl Exists in a flaw in resource initialization.Information may be obtained. Solution: For OpenShift Container Platform 4.8 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 errata update: https://docs.openshift.com/container-platform/4.8/release_notes/ocp-4-8-release-notes.html For Red Hat OpenShift Logging 5.1, see the following instructions to apply this update: https://docs.openshift.com/container-platform/4.8/logging/cluster-logging-upgrading.html 4.

Summary: Gatekeeper Operator v0.2 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: Gatekeeper Operator v0.2 Gatekeeper is an open source project that applies the OPA Constraint Framework to enforce policies on your Kubernetes clusters. This advisory contains the container images for Gatekeeper that include security updates, and container upgrades. 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. Note: Gatekeeper support from the Red Hat support team is limited cases where it is integrated and used with Red Hat Advanced Cluster Management for Kubernetes. For support options for any other use, see the Gatekeeper open source project website at: https://open-policy-agent.github.io/gatekeeper/website/docs/howto/. Security updates: * golang.org/x/crypto: empty plaintext packet causes panic (CVE-2021-43565) * golang: crypto/elliptic IsOnCurve returns true for invalid field elements (CVE-2022-23806) 3. Solution: Before applying this update, make sure all previously released errata relevant to your system have been applied. The requirements to apply the upgraded images are different whether or not you used the operator. Complete the following steps, depending on your installation: - - Upgrade gatekeeper operator: The gatekeeper operator that is installed by the gatekeeper operator policy has `installPlanApproval` set to `Automatic`. This setting means the operator will be upgraded automatically when there is a new version of the operator. No further action is required for upgrade. If you changed the setting for `installPlanApproval` to `manual`, then you must view each cluster to manually approve the upgrade to the operator. - - Upgrade gatekeeper without the operator: The gatekeeper version is specified as part of the Gatekeeper CR in the gatekeeper operator policy. To upgrade the gatekeeper version: a) Determine the latest version of gatekeeper by visiting: https://catalog.redhat.com/software/containers/rhacm2/gatekeeper-rhel8/5fadb4a18d9a79d2f438a5d9. b) Click the tag dropdown, and find the latest static tag. An example tag is 'v3.3.0-1'. c) Edit the gatekeeper operator policy and update the image tag to use the latest static tag. For example, you might change this line to image: 'registry.redhat.io/rhacm2/gatekeeper-rhel8:v3.3.0-1'. Refer to https://open-policy-agent.github.io/gatekeeper/website/docs/howto/ for additional information. 4.
