CVE-2014-2894

kvm has been updated to fix issues in the embedded qemu:

* 

  CVE-2014-0223: 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 have used this flaw to
  corrupt QEMU process memory on the host, which could potentially have
  resulted in arbitrary code execution on the host with the privileges
  of the QEMU process.

* 

  CVE-2014-3461: A user able to alter the savevm data (either on the
  disk or over the wire during migration) could have used this flaw to
  to corrupt QEMU process memory on the (destination) host, which could
  have potentially resulted in arbitrary code execution on the host
  with the privileges of the QEMU process.

* 

  CVE-2014-0222: 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 have used this flaw to
  corrupt QEMU process memory on the host, which could have potentially
  resulted in arbitrary code execution on the host with the privileges
  of the QEMU process.

Non-security bugs fixed:

* Fix exceeding IRQ routes that could have caused freezes of guests.
  (bnc#876842)
* Fix CPUID emulation bugs that may have broken Windows guests with
  newer -cpu types (bnc#886535)

Off-by-one error in the cmd_smart function in the smart self test in hw/ide/core.c in QEMU before 2.0 allows local users to have unspecified impact via a SMART EXECUTE OFFLINE command that triggers a buffer underflow and memory corruption.

Michael S. Tsirkin discovered that QEMU incorrectly handled vmxnet3 devices. A local guest could possibly use this issue to cause a denial of service, or possibly execute arbitrary code on the host. This issue only applied to Ubuntu 13.10 and Ubuntu 14.04 LTS. (CVE-2013-4544)

Michael S. Tsirkin discovered that QEMU incorrectly handled virtio-net MAC addresses. A local guest could possibly use this issue to cause a denial of service, or possibly execute arbitrary code on the host. (CVE-2014-0150)

Benoît Canet discovered that QEMU incorrectly handled SMART self-tests. A local guest could possibly use this issue to cause a denial of service, or possibly execute arbitrary code on the host. (CVE-2014-2894)
