CVE-2025-55198

Ein entfernter, anonymer Angreifer kann mehrere Schwachstellen in Red Hat OpenShift Container Platform ausnutzen, um einen Denial of Service Angriff durchzuführen.

A Helm contributor discovered an improper validation of type error when parsing Chart.yaml and index.yaml files that can lead to a panic. ### Impact There are two areas of YAML validation that were impacted. First, when a `Chart.yaml` file had a `null` maintainer or the `child` or `parent` of a dependencies `import-values` could be parsed as something other than a string, `helm lint` would panic. Second, when an `index.yaml` had an empty entry in the list of chart versions Helm would panic on interactions with that repository. ### Patches This issue has been resolved in Helm v3.18.5. ### Workarounds Ensure YAML files are formatted as Helm expects prior to processing them with Helm. ### References Helm's security policy is spelled out in detail in our [SECURITY](https://github.com/helm/community/blob/master/SECURITY.md) document. ### Credits Disclosed by Jakub Ciolek at AlphaSense.

Helm is a package manager for Charts for Kubernetes. Prior to version 3.18.5, when parsing Chart.yaml and index.yaml files, an improper validation of type error can lead to a panic. This issue has been resolved in Helm 3.18.5. A workaround involves ensuring YAML files are formatted as Helm expects prior to processing them with Helm.
