VDSM and libvirt in Red Hat Enterprise Virtualization Hypervisor (aka RHEV-H) 7-7.x before 7-7.2-20151119.0 and 6-6.x before 6-6.7-20151117.0 as packaged in Red Hat Enterprise Virtualization before 3.5.6 when VSDM is run with -spice disable-ticketing and a VM is suspended and then restored, allows remote attackers to log in without authentication via unspecified vectors.

oVirt Engine discloses the ENGINE_HTTPS_PKI_TRUST_STORE_PASSWORD in /var/log/ovirt-engine/engine.log file in RHEV before 4.0.

Virtual Desktop Server Manager (VDSM) in Red Hat Enterprise Virtualization (RHEV) 2.2 does not properly accept TCP connections for SSL sessions, which allows remote attackers to cause a denial of service (daemon outage) via crafted SSL traffic.

The subpage MMIO initialization functionality in the subpage_register function in exec.c in QEMU-KVM, as used in the Hypervisor (aka rhev-hypervisor) in Red Hat Enterprise Virtualization (RHEV) 2.2 and KVM 83, does not properly select the index for access to the callback array, which allows guest OS users to cause a denial of service (guest OS crash) or possibly gain privileges via unspecified vectors.

The Hypervisor (aka rhev-hypervisor) in Red Hat Enterprise Virtualization (RHEV) 2.2, and KVM 83, when the Intel VT-x extension is enabled, allows guest OS users to cause a denial of service (NULL pointer dereference and host OS crash) via vectors related to instruction emulation.

QEMU-KVM, as used in the Hypervisor (aka rhev-hypervisor) in Red Hat Enterprise Virtualization (RHEV) 2.2 and KVM 83, does not properly validate guest QXL driver pointers, which allows guest OS users to cause a denial of service (invalid pointer dereference and guest OS crash) or possibly gain privileges via unspecified vectors.

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.

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 validate guest QXL driver pointers, which allows guest OS users to cause a denial of service (invalid pointer dereference and guest OS crash) or possibly gain privileges via unspecified vectors.
