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_maintained cloud-init

Is cloud-init not used anymore?
Comment 4 Vincent Untz 2014-03-07 08:13:29 UTC
It's maintained by Robert, not by the SUSE Cloud team.
Comment 10 Marcus Meissner 2014-03-07 14:46:26 UTC
As we do not ship this anymore, and PubCloud uses 0.7.x, we can consider this fixed.
