Issue Overview:

Puppet 2.7.x before 2.7.5, 2.6.x before 2.6.11, and 0.25.x, when running in --edit mode, uses a predictable file name, which allows local users to run arbitrary Puppet code or trick a user into editing arbitrary files.

Puppet 2.7.x before 2.7.5, 2.6.x before 2.6.11, and 0.25.x allows local users to modify the permissions of arbitrary files via a symlink attack on the SSH authorized_keys file.

Puppet 2.7.x before 2.7.5, 2.6.x before 2.6.11, and 0.25.x allows local users to overwrite arbitrary files via a symlink attack on the .k5login file.
