Jan Rusnacko of Red Hat reports:

Katello code exposes potential to_sym Denial of Service attack vector from user input parameters. The two places identified are:

https://github.com/Katello/katello/blob/9231e24f93fa804e557fc95637cfa2c5bb92f6a7/app/controllers/katello/content_search_controller.rb#L617

This type of attack is documented here - http://docs.fedoraproject.org/en-US/Fedora_Security_Team/1/html/Secure_Ruby_Development_Guide/RubySymbols.html

This has been confirmed in testing by Eric Helms of Red Hat.
