MEDIUM 5.3EPSS 1.27%
Does this matter?
Lower severity and a low EPSS score (1.27%). Track it; it rarely justifies an emergency change on its own.
Description
The Puppet Communications Protocol (PCP) Broker incorrectly validates message header sizes. An attacker could use this to crash the PCP Broker, preventing commands from being sent to agents. This is resolved in Puppet Enterprise 2016.4.3 and 2016.5.2.
