vulnerability from the CVE link(s) in the References section.

Spacewalk is an Open Source systems management solution that provides
system provisioning, configuration and patching capabilities.

Security Fix(es) :

* It was found that spacewalk-channel can be used by a non-admin user

authorization check in backend/server/rhnChannel.py. (CVE-2017-7470)
