Descriptions

VDSM in Red Hat Enterprise Virtualization 3 and 3.2 allows privileged guest users to cause the host to become "unavailable to the managment server" via guestInfo dictionaries with "unexpected fields."

VDSM en Red Hat Enterprise Virtualization 3 y 3.2, permite a usuarios invitados con privilegios provocar que la maquina anfitriona "no esté disponible para el servidor de gestión" a través de diccionarios "guestInfo" con "campos inesperados".

The rhev-hypervisor6 package provides a Red Hat Enterprise Virtualization Hypervisor ISO disk image. The Red Hat Enterprise Virtualization Hypervisor is a dedicated Kernel-based Virtual Machine hypervisor. It includes everything necessary to run and manage virtual machines: A subset of the Red Hat Enterprise Linux operating environment and the Red Hat Enterprise Virtualization Agent. Note: Red Hat Enterprise Virtualization Hypervisor is only available for the Intel 64 and AMD64 architectures with virtualization extensions. A flaw was found in the way KVM initialized a guest's registered pv_eoi indication flag when entering the guest. An unprivileged guest user could potentially use this flaw to crash the host.
