CVE-2019-10150 atomic-openshift: OpenShift builds don't verify SSH Host Keys for the git repository
OpenShift builds don't seem to cache the SSH key of the git repository. This allows an attacker who can MiTM, take over DNS etc to supply their own content.
Discussion:
Created repro; confirmed against 3.9, 3.11 and 4.1 rc5.
---
Tracked to scmauth/sshkey.go within builder. Link here is for 3.11

Flagging 3.6 and later as all affected from observation of source code.
