Echo: helm.sh/helm/v3: security update to 3.17.4

high Tenable Cloud Security Plugin ID 465223

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Helm is a package manager for Charts for Kubernetes. Prior to 3.18.4, a specially crafted Chart.yaml file
 along with a specially linked Chart.lock file can lead to local code execution when dependencies are
 updated. Fields in a Chart.yaml file, that are carried over to a Chart.lock file when dependencies are
 updated and this file is written, can be crafted in a way that can cause execution if that same content
 were in a file that is executed (e.g., a bash.rc file or shell script). If the Chart.lock file is
 symlinked to one of these files updating dependencies will write the lock file content to the symlinked
 file. This can lead to unwanted execution. Helm warns of the symlinked file but did not stop execution due
 to symlinking. This issue has been resolved in Helm v3.18.4. (CVE-2025-53547)

Solution

Update the helm.sh/helm/v3 library and its related packages to version 3.17.4 or later.
