Description Kurt Seifried 2013-08-14 07:26:26 UTC 
Moses Mendoza (moses) reports:

Puppet Module Tool does not control permissions of modules it
installs, instead transferring permissions that existed when the
module is built. This could allow a malicious user to write to modify
the puppet module if their local username is the same as the username
originally used to create the module and the user has write permission
to the puppet module directory.
