Summary

Aliases are never checked in helm

Details

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.

Severity

3.7 (Low)

Vulnerability from cvelistv5 – Published: 2020-09-17 20:40 – Updated: 2024-08-04 13:08

Title

Aliases are never checked in Helm

Summary

In Helm before versions 2.16.11 and 3.3.2 there is 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. This issue has been patched in Helm 3.3.2 and 2.16.11. A possible workaround is to 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.

Severity

3.7 (Low)
