CVE-2018-10839 [MEDIUM] QEMU vulnerabilities
Title: QEMU vulnerabilities
Summary: Several security issues were fixed in QEMU.
Daniel Shapira and Arash Tohidi discovered that QEMU incorrectly handled
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)

QEMU: rtl8139: integer overflow leads to buffer overflow
Qemu has a Buffer Overflow in rtl8139_do_receive in hw/net/rtl8139.c because an incorrect integer data type is used.
An integer overflow issue was found in the RTL8139 NIC emulation in QEMU. It could occur while receiving packets over the network if the size value is greater than INT_MAX. Such overflow would lead to stack buffer overflow issue. A user inside guest could use this flaw to crash the QEMU process, resulting in DoS scenario.
