device. An attacker inside the guest could use this issue to cause QEMU to
crash, resulting in a denial of service. (CVE-2016-10028)

It was discovered that QEMU incorrectly handled the JAZZ RC4030 device. A
privileged attacker inside the guest could use this issue to cause QEMU to
crash, resulting in a denial of service. (CVE-2016-8667)

Jann Horn discovered that QEMU incorrectly handled VirtFS directory
sharing. A privileged attacker inside the guest could use this issue to
access files on the host file system outside of the shared directory and
possibly escalate their privileges. In the default installation, when QEMU
is used with libvirt, attackers would be isolated by the libvirt AppArmor
profile. (CVE-2016-9602)

Gerd Hoffmann discovered that QEMU incorrectly handled the Cirrus VGA
device when being used with a VNC connection. A privileged attacker inside
the guest could use this issue to cause QEMU to crash, resulting in a
denial of service, or possibly execute arbitrary code on the host. In the
default installation, when QEMU is used with libvirt, attackers would be
isolated by the libvirt AppArmor profile. (CVE-2016-9603)

Li Qiang discovered that QEMU incorrectly handled the Virtio GPU device. An
attacker inside the guest could use this issue to cause QEMU to leak
contents of host memory. (CVE-2016-9908)

Li Qiang discovered that QEMU incorrectly handled the Virtio GPU device. An
attacker inside the guest could use this issue to cause QEMU to crash,
resulting in a denial of service. (CVE-2016-9912, CVE-2017-5552,
CVE-2017-5578)

Li Qiang discovered that QEMU incorrectly handled VirtFS directory sharing.
A privileged attacker inside the guest could use this issue to cause QEMU
to crash, resulting in a denial of service. (CVE-2016-9914)

Jiang Xin and Wjjzhang discovered that QEMU incorrectly handled SDHCI
device emulation. A privileged attacker inside the guest could use this
issue to cause QEMU to crash, resulting in a denial of service.
(CVE-2017-5987)

Li Qiang discovered that QEMU incorrectly handled USB OHCI controller
emulation. A privileged attacker inside the guest could use this issue to
cause QEMU to hang, resulting in a denial of service. (CVE-2017-6505)");
