Overview

puppet is an automated configuration management tool.

Affected versions of this package are vulnerable to Improper Input Validation. Puppet operated on a model that a node with a valid certificate was entitled to all information in the system and that a compromised certificate allowed access to everything in the infrastructure. When a node's catalog falls back to the default node, the catalog can be retrieved for a different node by modifying facts for the Puppet run. This issue can be mitigated by setting strict_hostname_checking = true in puppet.conf on your Puppet master.
