The following security issues have been fixed :
Puppet’s certificate authority issued Puppet agent certificates capable of impersonating the Puppet master.
Compromised or rogue puppet agents could therefore use their certificates for MITM attacks. (CVE-2011-3872)
Note: If you’ve set the ‘certdnsnames’ option in your master’s puppet.conf file merely installing the updated packages is not sufficient to fix this problem. You need to either pick a new DNS name for the master and reconfigure all agents to use it or re-new certificates on all agents.
Please refer to the documentation in /usr/share/doc/packages/puppet/puppetlabs-cve20113872-0.

Directory traversal vulnerability in puppet allowed unauthenticated remote attackers to upload x.509 certificate signing requests to arbitrary locations.
(CVE-2011-3848)
Puppet was prone to several symlink attacks (CVE-2011-3870 / CVE-2011-3869 / CVE-2011-3871)
