TITLE

Red Hat Security Advisory 2021-5127-05

DESCRIPTION

An issue was discovered in GNOME GLib before 2.66.8. When g_file_replace() is used with G_FILE_CREATE_REPLACE_DESTINATION to replace a path that is a dangling symlink, it incorrectly also creates the target of the symlink as an empty file, which could conceivably have security relevance if the symlink is attacker-controlled. (If the path is a symlink to a file that already exists, then the contents of that file correctly remain unchanged.). GNOME Glib is a multi-platform toolkit for creating graphical user interfaces, and is the underlying core library of GTK+ and GNOME projects. The vulnerability is caused by g_file_replace and G_FILE_CREATE_REPLACE_DESTINATION incorrectly creating the target of a symbolic link as an empty file. Bugs fixed (https://bugzilla.redhat.com/): 1944888 - CVE-2021-21409 netty: Request smuggling via content-length header 2004133 - CVE-2021-37136 netty-codec: Bzip2Decoder doesn't allow setting size restrictions for decompressed data 2004135 - CVE-2021-37137 netty-codec: SnappyFrameDecoder doesn't restrict chunk length and may buffer skippable chunks in an unnecessary way 2030932 - CVE-2021-44228 log4j-core: Remote code execution in Log4j 2.x when logs contain an attacker-controlled string value 5.

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.
