Versions of Puppet prior to 4.10.1 will deserialize data off the wire (from the agent to the server, in this case) with a 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.

CVE-2017-10689 [MEDIUM] Puppet vulnerabilities
Title: Puppet vulnerabilities
Summary: Several security issues were fixed in Puppet.
It was discovered that Puppet installed modules with world writable
permissions. An attacker could use this vulnerability to execute arbitrary
code or cause a denial of service. (CVE-2017-10689)
It was discovered that Puppet could be used to force YAML deserialization in an
unsafe manner. A remote attacker could use this vulnerability for remote code
execution. (CVE-2017-2295)
Instructions: After a standard system update you need to restart Puppet to make
all the necessary changes.
