The remote OracleVM system is missing necessary patches to address critical security updates :
don’t generate weak control key for resolver (CVE-2014-9293)
don’t generate weak MD5 keys in ntp-keygen (CVE-2014-9294)
fix buffer overflows via specially-crafted packets (CVE-2014-9295)
don’t mobilize passive association when authentication fails (CVE-2014-9296)
