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

XSA-108. Additional changelog comments added to
- Fix for bug 19698535
- x86emul: only emulate software interrupt injection for
real mode Protected mode emulation currently lacks
proper privilege checking of the referenced IDT entry,
and there's currently no legitimate way for any of the
respective instructions to reach the emulator when the
guest is in protected mode. This is XSA-106.

Without this, it is possible for userspace to load its
own IDT or GDT. This is XSA-105. (CVE-2014-7155)
