CVE-2015-7295
Jason Wang of Red Hat Inc. discovered that the Virtual Network
Device support is vulnerable to denial-of-service, 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-2015-7549
Qinghao Tang of Qihoo 360 Inc. and Ling Liu of Qihoo 360
Inc. discovered that the PCI MSI-X emulator is vulnerable to a
null pointer dereference issue, that could lead to
denial-of-service (via application crash).

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-2015-8550
Felix Wilhelm of ERNW Research that the PV backend drivers are
vulnerable to double fetch vulnerabilities, possibly resulting in
arbitrary code execution.

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-2015-8567 CVE-2015-8568
Qinghao Tang of Qihoo 360 Inc. discovered that the vmxnet3 device
emulator could be used to intentionally leak host memory, thus
resulting in denial-of-service.

CVE-2015-8613
Qinghao Tang of Qihoo 360 Inc. discovered that the SCSI MegaRAID
SAS HBA emulation support is vulnerable to a stack-based buffer
overflow issue, that could lead to denial-of-service (via
application crash).

CVE-2015-8619
Ling Liu of Qihoo 360 Inc. discovered that the Human Monitor
Interface support is vulnerable to an out-of-bound write access
issue that could result in denial-of-service (via application
crash).

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-2015-8744
The vmxnet3 driver incorrectly processes small packets, which could
result in denial-of-service (via application crash).

CVE-2015-8745
The vmxnet3 driver incorrectly processes Interrupt Mask Registers,
which could result in denial-of-service (via application crash).

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).

CVE-2016-1981
The e1000 driver is vulnerable to an infinite loop issue that
could lead to denial-of-service (via application crash).");
