The remote OracleVM system is missing necessary patches to address critical security updates :
Fix and enable tests (%check).
Backport a change which makes tests exit with nonzero status when they fail.
Add a fix for upstream tests for CVE-2018-7750 (broken in previous).
Fix a security flaw (CVE-2018-7750) in Paramiko’s server mode (emphasis on server mode this doesnot impact client use!) Backported from 1.10: Resolves #1557140
