✅ Remediation

For details on how to apply this update, which includes the changes described in this advisory, refer to: https://images.redhat.com/ Workaround: Mitigation for this issue is either not available or the currently available options do not meet the criteria for vulnerability selection or Red Hat Product Security recommendation. Avoid processing untrusted AWK scripts with the busybox awk applet. Workaround: No mitigation is required for the vast majority of Red Hat products, as they do not ship the affected BusyBox version. For any product confirmed to ship the affected version, limiting the ash shell to trusted, non-adversarial script input reduces exposure until an update is available.
