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

  - CVE-2015-7295
    Jason Wang of Red Hat Inc. discovered that the Virtual
    Network Device support is vulnerable to
    denial-of-service (via resource exhaustion), that could
    occur when receiving large packets.

  - CVE-2015-7504
    Qinghao Tang of Qihoo 360 Inc. and Ling Liu of Qihoo 360
    Inc. discovered that the PC-Net II ethernet controller
    is vulnerable to a heap-based buffer overflow that could
    result in denial-of-service (via application crash) or
    arbitrary code execution.

  - CVE-2015-7512
    Ling Liu of Qihoo 360 Inc. and Jason Wang of Red Hat
    Inc. discovered that the PC-Net II ethernet controller
    is vulnerable to a buffer overflow that could result in
    denial-of-service (via application crash) or arbitrary
    code execution.

  - CVE-2015-8345
    Qinghao Tang of Qihoo 360 Inc. discovered that the
    eepro100 emulator contains a flaw that could lead to an
    infinite loop when processing Command Blocks, eventually
    resulting in denial-of-service (via application crash).

  - CVE-2015-8504
    Lian Yihan of Qihoo 360 Inc. discovered that the VNC
    display driver support is vulnerable to an arithmetic
    exception flaw that could lead to denial-of-service (via
    application crash).

  - CVE-2015-8558
    Qinghao Tang of Qihoo 360 Inc. discovered that the USB
    EHCI emulation support contains a flaw that could lead
    to an infinite loop during communication between the
    host controller and a device driver. This could lead to
    denial-of-service (via resource exhaustion).

  - CVE-2015-8743
    Ling Liu of Qihoo 360 Inc. discovered that the NE2000
    emulator is vulnerable to an out-of-bound read/write
    access issue, potentially resulting in information leak
    or memory corruption.

  - CVE-2016-1568
    Qinghao Tang of Qihoo 360 Inc. discovered that the IDE
    AHCI emulation support is vulnerable to a use-after-free
    issue, that could lead to denial-of-service (via
    application crash) or arbitrary code execution.

  - CVE-2016-1714
    Donghai Zhu of Alibaba discovered that the Firmware
    Configuration emulation support is vulnerable to an
    out-of-bound read/write access issue, that could lead to
    denial-of-service (via application crash) or arbitrary
    code execution.

  - CVE-2016-1922
    Ling Liu of Qihoo 360 Inc. discovered that 32-bit
    Windows guests support is vulnerable to a NULL pointer
    dereference issue, that could lead to denial-of-service
    (via application crash)."
