NE2000 device emulation. An attacker inside the guest could use this issue
to cause QEMU to crash, resulting in a denial of service. (CVE-2018-10839)

It was discovered that QEMU incorrectly handled the Slirp networking
back-end. 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.
This issue only affected Ubuntu 14.04 LTS, Ubuntu 16.04 LTS and Ubuntu
18.04 LTS. (CVE-2018-11806)

Fakhri Zulkifli discovered that the QEMU guest agent incorrectly handled
certain QMP commands. An attacker could possibly use this issue to crash
the QEMU guest agent, resulting in a denial of service. (CVE-2018-12617)

Li Qiang discovered that QEMU incorrectly handled NVM Express Controller
emulation. An 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. This
issue only affected Ubuntu 18.04 LTS and Ubuntu 18.10. (CVE-2018-16847)

Daniel Shapira and Arash Tohidi discovered that QEMU incorrectly handled
RTL8139 device emulation. An attacker inside the guest could use this issue
to cause QEMU to crash, resulting in a denial of service. (CVE-2018-17958)

Daniel Shapira and Arash Tohidi discovered that QEMU incorrectly handled
PCNET device emulation. An attacker inside the guest could use this issue
to cause QEMU to crash, resulting in a denial of service. (CVE-2018-17962)

Daniel Shapira discovered that QEMU incorrectly handled large packet sizes.
An attacker inside the guest could use this issue to cause QEMU to crash,
resulting in a denial of service. (CVE-2018-17963)

It was discovered that QEMU incorrectly handled LSI53C895A device
emulation. An attacker inside the guest could use this issue to cause QEMU
