"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.
    0.5 for detailed instructions and scripts.

    nt-altnames-vulnerability/

  - 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)"
