"The version of cert-manager / helm installed on the remote Azure Linux 3.0 host is prior to tested version. It is,
therefore, affected by a vulnerability as referenced in the CVE-2024-25620 advisory.

  - Helm is a tool for managing Charts. Charts are packages of pre-configured Kubernetes resources. When
    either the Helm client or SDK is used to save a chart whose name within the `Chart.yaml` file includes a
    relative path change, the chart would be saved outside its expected directory based on the changes in the
    relative path. The validation and linting did not detect the path changes in the name. This issue has been
    resolved in Helm v3.14.1. Users unable to upgrade should check all charts used by Helm for path changes in
    their name as found in the `Chart.yaml` file. This includes dependencies. (CVE-2024-25620)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
