RedHat: RHSA-2021-3925:01 Important: Red Hat Advanced Cluster Management
Summary
Red Hat Advanced Cluster Management for Kubernetes 2.3.3 images
Red Hat Advanced Cluster Management for Kubernetes provides the
capabilities to address common challenges that administrators and site
reliability engineers face as they work across a range of public and
private cloud environments. Clusters and applications are all visible and
managed from a single console—with
security policy built in.
This advisory contains the container images for Red Hat Advanced Cluster
Management for Kubernetes, which fix several bugs and provide security
updates. See the following Release Notes documentation, which will be
updated shortly for this release, for additional details about this
release:
gement_for_kubernetes/2.3/html/release_notes/
Note: Because Red Hat OpenShift Container Platform version 4.9 was just
released, the functional testing of the compatibility between Red Hat
Advanced Cluster Management 2.3.3 and Red Hat OpenShift Container Platform
version 4.9 is still in progress.
Security fixes:
* nginx: Off-by-one in ngx_resolver_copy() when labels are followed by a
pointer to a root domain name (CVE-2021-23017)
* redis: Lua scripts can overflow the heap-based Lua stack (CVE-2021-32626)
* redis: Integer overflow issue with Streams (CVE-2021-32627)
* redis: Integer overflow bug in the ziplist data structure
(CVE-2021-32628)
* redis: Integer overflow issue with intsets (CVE-2021-32687)
* redis: Integer overflow issue with strings (CVE-2021-41099)
* redis: Out of bounds read in lua debugger protocol parser
(CVE-2021-32672)
* redis: Denial of service via Redis Standard Protocol (RESP) request
(CVE-2021-32675)
* helm: information disclosure vulnerability (CVE-2021-32690)
Bug fixes:
* KUBE-API: Support move agent to different cluster in the same namespace
(BZ# 1977358)
* Add columns to the Agent CRD list (BZ# 1977398)
* ClusterDeployment controller watches all Secrets from all namespaces (BZ#
1986081)
* RHACM 2.3.3 images (BZ# 1999365)
* Workaround for Network Manager not supporting nmconnections priority (BZ#
2001294)
* create cluster page empty in Safary Browser (BZ# 2002280)
* Compliance state doesn't get updated after fixing the issue causing
initially the policy not being able to update the managed object (BZ#
2002667)
* Overview page displays VMware based managed cluster as other (BZ#
2004188)
