Advisories for Gem/Backup-Agoddard package

(1) lib/backup/cli/utility.rb in the backup-agoddard gem and (2) lib/backup/cli/utility.rb in the backup_checksum gem for Ruby place credentials on the openssl command line, which allows local users to obtain sensitive information by listing the process.

If it is used in the context of a RoR application, since the user input isn't properly sanitized, the method decrypt in /lib/backup/cli/utility.rb is vulnerable to command injection.
