The remote Oracle Linux 5 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2015-0869 advisory. - Resolves: bz1152982 CVE-2014-3610 kernel: kvm: noncanonical MSR writes rhel-5.11.z Tenable has extracted the preceding description block directly fro...
kernel: kvm: noncanonical MSR writes
It was found that KVM's Write to Model Specific Register WRMSR instruction emulation would write non-canonical values passed in by the guest to certain MSRs in the host's context. A privileged guest user could use this flaw to crash the host...

CVE-2014-7890
The CVE-2014-7890 issue affects HP Point of Sale systems using OPOS drivers (OPOS CCOs) prior to version 1.13.003. The root cause is in OPOSToneIndicator.ocx used by HP POS Keyboard and POS Keyboard with MSR, allowing remote code execution when an attacker can influence inputs to the Open method ...
CVE-2014-7891
The CVE-2014-7891 issue affects HP Point of Sale PCs running Windows with OPOS Drivers, specifically the OPOSPOSKeyboard.ocx component. The Open method input validation flaw leads to a buffer overflow that could enable remote code execution. Products impacted include OPOS CCO drivers (pre‑1.13.00...
CVE-2015-0239
The emsysenter function in arch/x86/kvm/emulate.c in the Linux kernel before 3.18.5, when the guest OS lacks SYSENTER MSR initialization, allows guest OS users to gain guest OS privileges or cause a denial of service guest OS crash by triggering use of a 16-bit code segment for emulation of a...
