Description Vincent Danen 2011-09-30 21:33:20 UTC 
A flaw was found in the way puppet handled the k5login type.  The k5login type is typically used to manage a file in the home directory of a user.  It would write to the target file, as root, without doing anything to secure the file.  This would allow the owner of the home directory to symlink to anything on the system, and have the contents replaced, as root.

This is corrected in upstream 2.6.11 and 2.7.5 releases.
