libspice, as used in QEMU-KVM in the Hypervisor (aka rhev-hypervisor) in Red Hat Enterprise Virtualization (RHEV) 2.2 and qspice 0.3.0, does not properly restrict the addresses upon which memory-management actions are performed, which allows guest OS users to cause a denial of service (guest OS crash) or possibly gain privileges via unspecified vectors.
Weaknesses in this category are related to the management of permissions, privileges, and other security features that are used to perform access control.
