"This is an upstream security release. It addresses a number of issues
found in puppet-2.6.x. The Red Hat security team has rated this update
as having low security impact.

Refer to the upstream release notes and bugzilla entries for further
details.

http://projects.puppetlabs.com/projects/1/wiki/Release_Notes#2.6.17

NetworkManager compatibility should be improved in this release,
thanks to Orion Poplawski (any bugs in implementing Orion's suggested
dispatcher script are my own).

Note that Tenable Network Security has extracted the preceding
description block directly from the Fedora security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."

"Directory traversal vulnerability in lib/puppet/reports/store.rb in
Puppet before 2.6.17 and 2.7.x before 2.7.18, and Puppet Enterprise
before 2.5.2, when Delete is enabled in auth.conf, allows remote
authenticated users to delete arbitrary files on the puppet master
server via a .. (dot dot) in a node name.

Puppet before 2.6.17 and 2.7.x before 2.7.18, and Puppet Enterprise
before 2.5.2, allows remote authenticated users to read arbitrary
files on the puppet master server by leveraging an arbitrary user's
certificate and private key in a GET request.

lib/puppet/ssl/certificate_authority.rb in Puppet before 2.6.17 and
2.7.x before 2.7.18, and Puppet Enterprise before 2.5.2, does not
properly restrict the characters in the Common Name field of a
Certificate Signing Request (CSR), which makes it easier for
user-assisted remote attackers to trick administrators into signing a
crafted agent certificate via ANSI control sequences.

lib/puppet/defaults.rb in Puppet 2.7.x before 2.7.18, and Puppet
Enterprise before 2.5.2, uses 0644 permissions for
last_run_report.yaml, which allows local users to obtain sensitive
configuration information by leveraging access to the puppet master
server to read this file."
