Helm - v3.11.1

Security
Verified

Helm v3.11.1 is a security (patch) release. Users are strongly recommended to update to this release.

The template function getHostByName can be used to disclose information. More details are available in the CVE.

This release introduces a breaking changes to Helm:

  • When using the helm client for the template, install, and upgrade commands there is a new flag. --enable-dns needs to be set for the getHostByName template function to attempt to lookup an IP address for a given hostname. If the flag is not set the template function will return an empty string and skip looping up an IP address for the host.
  • The Helm SDK has added the EnableDNS property to the install action, the upgrade action, and the Engine. This property must be set to true for the in order for the getHostByName template function to attempt to lookup an IP address.

The default for both of these cases is false.

Philipp Stehle at SAP disclosed the vulnerability to the Helm project.
