CVE-2013-4344 [HIGH] QEMU vulnerabilities
Title: QEMU vulnerabilities
Summary: Several security issues were fixed in QEMU.
Asias He discovered that QEMU incorrectly handled SCSI controllers with
more than 256 attached devices. A local user could possibly use this flaw
to elevate privileges. (CVE-2013-4344)
It was discovered that QEMU incorrectly handled Xen disks. A local guest
could possibly use this flaw to consume resources, resulting in a denial of
service. This issue only affected Ubuntu 12.10 and Ubuntu 13.10.

CVE-2013-4377 qemu: hot-unplugging virtio devices in guest can crash host qemu process
A dangling pointer access flaw was found in the way qemu handled hot-unplugging virtio devices. This flaw was introduced by virtio refactoring and exists in the virtio-pci implementation. When the virtio-blk-pci device is deleted, the virtio-blk-device is removed first (removal is done in post-order). Later, the virtio-blk-device is accessed again, but proxy->vdev->vq is no longer valid (a dangling pointer) and kvm_set_ioeventfd_pio fails.
A privileged guest user could use this flaw to crash the qemu process on the host system, causing a denial of service to it and any other running virtual machines.
