Descriptions
The kvm_set_msr_common function in arch/x86/kvm/x86.c in the Linux kernel through 3.8.4 does not ensure a required time_page alignment during an MSR_KVM_SYSTEM_TIME operation, which allows guest OS users to cause a denial of service (buffer overflow and host OS memory corruption) or possibly have unspecified other impact via a crafted application.
La función kvm_set_msr_common en arch/x86/kvm/x86.c en el kernel de Linux hasta v3.8.4 no asegura una alineación time_page requerido durante una operación MSR_KVM_SYSTEM_TIME, que permite a usuarios de sistemas operativos invitados para causar una denegación de servicios (desbordamiento de memoria y corrupción de memoria en el sistema operativo anfitrión) o posiblemente tener un impacto no especificado a través de una aplicación diseñada.
