The remote OracleVM system is missing necessary patches to address critical security updates :
add disable monitor to default ntp.conf [CVE-2013-5211]
don’t limit rate of packets from sources (CVE-2016-7426)
don’t change interface from received packets (CVE-2016-7429)
fix calculation of root distance again (CVE-2016-7433)
require authentication for trap commands (CVE-2016-9310)
fix crash when reporting peer event to trappers (CVE-2016-9311)
