TITLE

Red Hat Security Advisory 2022-1081-01

DESCRIPTION

curl 7.1.1 to and including 7.75.0 is vulnerable to an "Exposure of Private Personal Information to an Unauthorized Actor" by leaking credentials in the HTTP Referer: header. libcurl does not strip off user credentials from the URL when automatically populating the Referer: HTTP request header field in outgoing HTTP requests, and therefore risks leaking sensitive data to the server that is the target of the second HTTP request. This could lead to exposure of the credentials to the server to which requests were redirected. (CVE-2021-22876) A vulnerability was found in curl where a flaw in the option parser for sending NEW_ENV variables libcurl can pass uninitialized data from a stack-based buffer to the server. The highest threat from this vulnerability is to confidentiality. (CVE-2021-22898). -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 ==================================================================== Red Hat Security Advisory Synopsis: Moderate: Gatekeeper Operator v0.2 security updates and bug fixes Advisory ID: RHSA-2022:1081-01 Product: Red Hat ACM Advisory URL: https://access.redhat.com/errata/RHSA-2022:1081 Issue date: 2022-03-28 CVE Names: CVE-2019-5827 CVE-2019-13750 CVE-2019-13751 CVE-2019-17594 CVE-2019-17595 CVE-2019-18218 CVE-2019-19603 CVE-2019-20838 CVE-2020-12762 CVE-2020-13435 CVE-2020-14155 CVE-2020-16135 CVE-2020-24370 CVE-2021-3200 CVE-2021-3445 CVE-2021-3521 CVE-2021-3580 CVE-2021-3712 CVE-2021-3800 CVE-2021-3999 CVE-2021-20231 CVE-2021-20232 CVE-2021-22876 CVE-2021-22898 CVE-2021-22925 CVE-2021-23177 CVE-2021-28153 CVE-2021-31566 CVE-2021-33560 CVE-2021-36084 CVE-2021-36085 CVE-2021-36086 CVE-2021-36087 CVE-2021-42574 CVE-2021-43565 CVE-2022-23218 CVE-2022-23219 CVE-2022-23308 CVE-2022-23806 CVE-2022-24407 ==================================================================== 1. 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.
