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

  - x86/HVM: properly bound x2APIC MSR range This is     XSA-108. Additional changelog comments added to     4.1.3-25.el5.94.1.3 (CVE-2014-7188)

  - Fix for bug 19698532

  - 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.
    (CVE-2014-7156)

  - x86/emulate: check cpl for all privileged instructions     Without this, it is possible for userspace to load its     own IDT or GDT. This is XSA-105. (CVE-2014-7155)

The remote host is affected by the vulnerability described in GLSA-201412-42 (Xen: Denial of Service)

    Multiple vulnerabilities have been discovered in Xen. Please review the       CVE identifiers referenced below for details.
  Impact :

    A local user could possibly cause a Denial of Service condition.
  Workaround :

    There is no known workaround at this time.
