Note: Additionally, a problem within the indirector/file.rb terminus base class exists. However, the problematic code is not used outside of unit tests. SOLUTION: Apply hotfixes for Puppet Enterprise versions 1.0, 1.1, and 1.2.x or update to Puppet versions 2.6.11 or 2.7.5. PROVIDED AND/OR DISCOVERED BY: 1) Ricky Zhou 2, 3) Reported by the vendor.
