An out-of-bounds read/write access flaw was found in the USB emulator of the QEMU in versions before 5.2.0. This issue occurs while processing USB packets from a guest when USBDevice 'setup_len' exceeds its 'data_buf[4096]' in the do_token_in, do_token_out routines. This flaw allows a guest user to crash the QEMU process, resulting in a denial of service, or the potential execution of arbitrary code with the privileges of the QEMU process on the host.

Title: QEMU vulnerabilities
Summary: Several security issues were fixed in QEMU.
USN-4467-1 fixed several vulnerabilities in QEMU. This update provides
the corresponding update for Ubuntu 14.04 ESM.
Original advisory details:
It was discovered that the QEMU SD memory card implementation incorrectly
handled certain memory operations. An attacker inside a guest could
possibly use this issue to cause QEMU to crash, resulting in a denial of
service. (CVE-2020-13253)
Ren Ding and Hanqing Zhao discovered that the QEMU ES1370 audio driver
incorrectly handled certain invalid frame counts. An attacker inside a

CVE-2020-14364 QEMU vulnerability
Title: QEMU vulnerability
Summary: QEMU could be made to crash or run programs.
Ziming Zhang, Xiao Wei, Gonglei Arei, and Yanyu Zhang discovered that QEMU
incorrectly handled certain USB packets. 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.
Instructions: After a standard system update you need to restart all QEMU virtual
machines to make all the necessary changes.
