The console in Puppet Enterprise 2015.x and 2016.x prior to 2016.4.0 includes unsafe string reads that potentially allows for remote code execution on the console node.

The pxp-agent component in Puppet Enterprise 2015.3.x before 2015.3.3 and Puppet Agent 1.3.x before 1.3.6 does not properly validate server certificates, which might allow remote attackers to spoof brokers and execute arbitrary commands via a crafted certificate.

Puppet Enterprise 2015.3 before 2015.3.1 allows remote attackers to bypass a host whitelist protection mechanism by leveraging the Puppet communications protocol.
