CVE-2017-2292 Information

Description

Versions of MCollective prior to 2.10.4 deserialized YAML from agents without calling safe_load allowing the potential for arbitrary code execution on the server. The fix for this is to call YAML.safe_load on input. This has been tested in all Puppet-supplied MCollective plugins but there is a chance that third-party plugins could rely on this insecure behavior.
