✅ Remediation

For details on how to apply this update, which includes the changes described in this advisory, refer to: https://images.redhat.com/ Workaround: Avoid building container images using BuildKit frontends from untrusted sources. A BuildKit frontend is typically specified using a "# syntax" directive at the top of a Dockerfile, or with the "--frontend" option to the "buildctl build" command. Only use frontend images that come from a trusted source. Workaround: Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
