Details
It was discovered that Puppet incorrectly handled the non-default
“certdnsnames” option when generating certificates. If this setting was
added to puppet.conf, the puppet primary server’s DNS alt names were added
to the X.509 Subject Alternative Name field of all certificates, not just
the puppet primary server’s certificate. An attacker that has an incorrect
agent certificate in his possession can use it to impersonate the puppet
primary server in a machine-in-the-middle attack.
