CVE-2012-6639 cloud-init: insecure transmission of EC2 instance data can lead to root privilege escalation
It was reported [1],[2] that 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 issue was found and silently fixed in 2012; version 0.7.0 contains the fix [3].
