Overview

puppet is an automated configuration management tool.

Affected versions of this package are vulnerable to Deserialization of Untrusted Data. It allows deserializing data off the wire (from the agent to the server, in this case) with an attacker-specified format. This could be used to force YAML deserialization in an unsafe manner, which would lead to remote code execution. This change constrains the format of data on the wire to PSON or safely decoded YAML.
