Upgrade helm.sh/helm/v3/pkg/chartutil to version 3.18.5 or higher.
Overview
helm.sh/helm/v3/pkg/chartutil is a package manager for kubernetes.
Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling via the processing of JSON Schema files containing $ref fields that point to device files such as /dev/zero. An attacker can cause memory exhaustion and termination of the process by supplying a malicious chart with specially crafted schema references.
Workaround
This vulnerability can be mitigated by ensuring that all loaded charts do not contain $ref fields pointing to /dev/zero.
