✅ Remediation

For details on how to apply this update, which includes the changes described in this advisory, refer to: https://access.redhat.com/articles/11258 Workaround: Red Hat Enterprise Linux (RHEL) and OpenShift ships with SELinux in targeted enforcing mode, which prevents the container processes from accessing host content and mitigates this attack. Dockerfiles can be inspected on the 'RUN' and 'WORKDIR' directives to ensure that there are no escapes or malicious paths, which are an indication of compromise. Limiting access and only using trusted container images can help prevent unauthorized access and malicious attacks.
