This was reported and fixed silently in 2012, so it would need a 2012 CVE name. (This issue is not specific to cloud-init, there seem to be some wget scripts out there which exhibit the same behavior, but it's probably some custom stuff that's not distributed anywhere, so no CVE is needed for that.) -- Florian Weimer / Red Hat Product Security Team
