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: pcnet: integer overflow leads to buffer overflow
Qemu has a Buffer Overflow in pcnet_receive in hw/net/pcnet.c because an incorrect integer data type is used.
An integer overflow issue was found in the AMD PC-Net II NIC emulation in QEMU. It could occur while receiving packets, if the size value was 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.

## Abstract
This paper presents results from the MSR 2021 Hackathon. Our team investigates files/projects that contain known security vulnerabilities and how widespread they are throughout repositories in open source software.
These security vulnerabilities can potentially be propagated through code reuse even when the vulnerability is fixed in different versio

CVE-2018-17962 QEMU: pcnet: integer overflow leads to buffer overflow
Qemu emulator built with the AMD PC-Net II (Am79C970A) emulation support is vulnerable to an integer overflow, which could lead to buffer overflow issue. It could occur when receiving packets over the network.
A user inside guest could use this flaw to crash the Qemu process resulting in DoS.
