An out-of-bounds flaw was found in the QEMU emulator built using
'address_space_translate' to map an address to a MemoryRegionSection. The
flaw could occur while doing pci_dma_read/write calls, resulting in an
out-of-bounds read-write access error. A privileged user inside a guest could
use this flaw to crash the guest instance (denial of service) (CVE-2015-8817,
CVE-2015-8818).

A NULL-pointer dereference flaw was found in the QEMU emulator built with TPR
optimization for 32-bit Windows guests support. The flaw occurs when doing
I/O-port write operations from the HMP interface. The 'current_cpu' value
remains null because it is not called from the cpu_exec() loop, and
dereferencing it results in the flaw. An attacker with access to the HMP
interface could use this flaw to crash the QEMU instance (denial of service)
(CVE-2016-1922).

It was discovered that QEMU incorrectly handled the e1000 device. An
attacker inside the guest could use this issue to cause QEMU to crash,
resulting in a denial of service (CVE-2016-1981).

Zuozhi Fzz discovered that QEMU incorrectly handled IDE AHCI emulation. An
attacker inside the guest could use this issue to cause QEMU to crash,
resulting in a denial of service (CVE-2016-2197).

Zuozhi Fzz discovered that QEMU incorrectly handled USB EHCI emulation. An
attacker inside the guest could use this issue to cause QEMU to crash,
resulting in a denial of service (CVE-2016-2198).

Zuozhi Fzz discovered that QEMU incorrectly handled USB OHCI emulation
support. A privileged attacker inside the guest could use this issue to
cause QEMU to crash, resulting in a denial of service (CVE-2016-2391).

Qinghao Tang discovered that QEMU incorrectly handled USB Net emulation
support. A privileged attacker inside the guest could use this issue to
cause QEMU to crash, resulting in a denial of service (CVE-2016-2392).

Qinghao Tang discovered that QEMU incorrectly handled USB Net emulation
support. A privileged attacker inside the guest could use this issue to
cause QEMU to crash, resulting in a denial of service, or possibly leak
host memory bytes (CVE-2016-2538).

Hongke Yang discovered that QEMU incorrectly handled NE2000 emulation
support. A privileged attacker inside the guest could use this issue to
cause QEMU to crash, resulting in a denial of service (CVE-2016-2841).

Ling Liu discovered that QEMU incorrectly handled IP checksum routines. An
attacker inside the guest could use this issue to cause QEMU to crash,
resulting in a denial of service, or possibly leak host memory bytes
(CVE-2016-2857).

It was discovered that QEMU incorrectly handled the PRNG back-end support.
An attacker inside the guest could use this issue to cause QEMU to crash,
resulting in a denial of service (CVE-2016-2858).

Wei Xiao and Qinghao Tang discovered that QEMU incorrectly handled access
in the VGA module. A privileged ... [Please see the references for more information on the vulnerabilities]");
