✅ 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 Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability. Workaround: There is no configuration change that fully prevents this issue; upgrading to a fixed version of Helm resolves it. As a workaround, verify that Helm charts obtained from third-party or untrusted sources do not contain zero-byte files before processing them with `helm template`, `helm install`, `helm upgrade`, `helm lint`, or the SDK Engine.Render function.
