CVE-2014-3615
The VGA emulator in QEMU allows local guest users to read host memory by setting the display to a high resolution...
Qemu: information leakage when guest sets high resolution
An information leak flaw was found in the way QEMU's VGA emulator accessed frame buffer memory for high resolution displays. A privileged guest user could use this flaw to leak memory contents of the host to the guest by setting the display to use a high resolution in the guest...
Qemu: qcow1: validate L2 table size to avoid integer overflows
An integer overflow flaw was found in the QEMU block driver for QCOW version 1 disk images. A user able to alter the QEMU disk image files loaded by a guest could use this flaw to corrupt QEMU process memory on the host, which could potentially result in arbitrary code execution on the host with...
Qemu: qcow1: validate image size to avoid out-of-bounds memory access
An integer overflow flaw was found in the QEMU block driver for QCOW version 1 disk images. A user able to alter the QEMU disk image files loaded by a guest could use this flaw to corrupt QEMU process memory on the host, which could potentially result in arbitrary code execution on the host with...

qemu: virtio: insufficient validation of num_sg when mapping
An user able to alter the savevm data either on the disk or over the wire during migration could use this flaw to to corrupt QEMU process memory on the destination host, which could potentially result in arbitrary code execution on the host with the privileges of the QEMU process...
kernel: kvm: out-of-bounds access in ioapic indirect register reads
The ioapicreadindirect function in virt/kvm/ioapic.c in the Linux kernel through 3.8.4 does not properly handle a certain combination of invalid IOAPICREGSELECT and IOAPICREGWINDOW operations, which allows guest OS users to obtain sensitive information from host OS memory or cause a denial of...
kernel: kvm: buffer overflow in handling of MSR_KVM_SYSTEM_TIME
The kvmsetmsrcommon function in arch/x86/kvm/x86.c in the Linux kernel through 3.8.4 does not ensure a required timepage alignment during an MSRKVMSYSTEMTIME operation, which allows guest OS users to cause a denial of service buffer overflow and host OS memory corruption or possibly have...
