"Several vulnerabilities were discovered in qemu-kvm, a full
virtualization solution on x86 hardware.

  - CVE-2015-5278
    Qinghao Tang of QIHU 360 Inc. discovered an infinite
    loop issue in the NE2000 NIC emulation. A privileged
    guest user could use this flaw to mount a denial of
    service (QEMU process crash).

  - CVE-2015-5279
    Qinghao Tang of QIHU 360 Inc. discovered a heap buffer
    overflow flaw in the NE2000 NIC emulation. A privileged
    guest user could use this flaw to mount a denial of
    service (QEMU process crash), or potentially to execute
    arbitrary code on the host with the privileges of the
    hosting QEMU process.

  - CVE-2015-6815
    Qinghao Tang of QIHU 360 Inc. discovered an infinite
    loop issue in the e1000 NIC emulation. A privileged
    guest user could use this flaw to mount a denial of
    service (QEMU process crash).

  - CVE-2015-6855
    Qinghao Tang of QIHU 360 Inc. discovered a flaw in the
    IDE subsystem in QEMU occurring while executing IDE's
    WIN_READ_NATIVE_MAX command to determine the maximum
    size of a drive. A privileged guest user could use this
    flaw to mount a denial of service (QEMU process crash)."
