Posted on 26 July 2021
RedHat===================================================================== Red Hat Security Advisory
Synopsis: Important: OpenShift Container Platform 4.7.21 security and bug fix update
Advisory ID: RHSA-2021:2763-01
Product: Red Hat OpenShift Enterprise
Advisory URL: https://access.redhat.com/errata/RHSA-2021:2763
Issue date: 2021-07-26
CVE Names: CVE-2021-33909 CVE-2021-33910
=====================================================================
1. Summary:
An update is now available for Red Hat OpenShift Container Platform 4.7.
Red Hat Product Security has rated this update as having a security impact
of Important. 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. Relevant releases/architectures:
Red Hat OpenShift Container Platform 4.7 - 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.
The kernel packages contain the Linux kernel, the core of any Linux
operating system.
The kernel-rt packages provide the Real Time Linux Kernel, which enables
fine-tuning for systems with extremely high determinism requirements.
Ansible is a SSH-based configuration management, deployment, and task
execution system. The openshift-ansible packages contain Ansible code and
playbooks for installing and upgrading OpenShift Container Platform 3.
The systemd packages contain systemd, a system and service manager for
Linux, compatible with the SysV and LSB init scripts. It provides
aggressive parallelism capabilities, uses socket and D-Bus activation for
starting services, offers on-demand starting of daemons, and keeps track of
processes using Linux cgroups. In addition, it supports snapshotting and
restoring of the system state, maintains mount and automount points, and
implements an elaborate transactional dependency-based service control
logic. It can also work as a drop-in replacement for sysvinit.
Security Fix(es):
* kernel: size_t-to-int conversion vulnerability in the filesystem layer
(CVE-2021-33909)
* systemd: uncontrolled allocation on the stack in function
unit_name_path_escape leads to crash (CVE-2021-33910)
For more details about the security issue(s), including the impact, a CVSS
score, acknowledgments, and other related information, refer to the CVE
page(s) listed in the References section.
Bug Fix(es):
* kernel-rt: update RT source tree to the RHEL-8.3.z source tree
(BZ#1957359)
* Placeholder bug for OCP 4.7.0 rpm release (BZ#1983534)
4. 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:
