The remote OracleVM system is missing necessary patches to address critical security updates :

  • add disable monitor to default ntp.conf [CVE-2013-5211]

  • fix buffer overflow in datum refclock driver (CVE-2017-6462)

  • fix crash with invalid unpeer command (CVE-2017-6463)

  • fix potential crash with invalid server command (CVE-2017-6464)

  • 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)

  • don’t allow spoofed packets to demobilize associations (CVE-2015-7979, CVE-2016-1547)

  • don’t allow spoofed packet to enable symmetric interleaved mode (CVE-2016-1548)

  • check mode of new source in config command (CVE-2016-2518)

  • make MAC check resilient against timing attack (CVE-2016-1550)
