## Overview

### Impact

During a security audit of Helm's code base, security researchers at Trail of Bits identified a bug in which the `alias` field on a `Chart.yaml` is not properly sanitized. This could lead to the injection of unwanted information into a chart.

### Patches

This issue has been patched in Helm 3.3.2 and 2.16.11

### Specific Go Packages Affected
helm.sh/helm/v3/pkg/chartutil

### Workarounds

Manually review the `dependencies` field of any untrusted chart, verifying that the `alias` field is either not used, or (if used) does not contain newlines or path characters.

## Affected packages

- `helm.sh/helm/v3 >= 3.0.0, < 3.3.2`
- `helm.sh/helm < 2.16.11`

## Remediation

Upgrade to a patched release:

- `helm.sh/helm/v3 3.3.2`
- `helm.sh/helm 2.16.11`
