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: slirp: heap buffer overflow while reassembling fragmented datagrams
m_cat in slirp/mbuf.c in Qemu has a heap-based buffer overflow via incoming fragmented datagrams.
A heap buffer overflow issue was found in the way SLiRP networking back-end in QEMU processes fragmented packets. It could occur while reassembling the fragmented datagrams of an incoming packet. A privileged user/process inside guest could use this flaw to crash the QEMU process resulting in DoS or potentially leverage it to execute arbitrary code on the host with privileges of the QEMU process.
