"The remote SUSE Linux SLES15 / SLES_SAP15 / openSUSE 15 host has packages installed that are affected by multiple
vulnerabilities as referenced in the SUSE-SU-2024:1137-1 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)

  - Helm is a package manager for Charts for Kubernetes. Versions prior to 3.14.2 contain an uninitialized
    variable vulnerability when Helm parses index and plugin yaml files missing expected content. When either
    an `index.yaml` file or a plugins `plugin.yaml` file were missing all metadata a panic would occur in
    Helm. In the Helm SDK, this is found when using the `LoadIndexFile` or `DownloadIndexFile` functions in
    the `repo` package or the `LoadDir` function in the `plugin` package. For the Helm client this impacts
    functions around adding a repository and all Helm functions if a malicious plugin is added as Helm
    inspects all known plugins on each invocation. This issue has been resolved in Helm v3.14.2. If a
    malicious plugin has been added which is causing all Helm client commands to panic, the malicious plugin
    can be manually removed from the filesystem. If using Helm SDK versions prior to 3.14.2, calls to affected
    functions can use `recover` to catch the panic. (CVE-2024-26147)

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