Subject: [oss-security] CVE request: cloud-init DNS resolution fix
Prior to version 0.7.0, cloud-init could send requests for EC2 instance data to untrusted systems:
This could allow someone who has control over a suitable domain name to obtain root rights on an affected system.
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.)

revising last comment ...
Is cloud-init not used anymore?
It's maintained by Robert, not by the SUSE Cloud team.
As we do not ship this anymore, and PubCloud uses 0.7.x, we can consider this fixed.
