Multiple security issues were discovered in QEMU, a fast processor

    An integer overflow in the sm501 display device may result in denial of
    service.

CVE-2020-14364

    An out-of-bands write in the USB emulation code may result in
    guest-to-host code execution.

CVE-2020-15863

    A buffer overflow in the XGMAC network device may result in denial of
    service or the execution of arbitrary code.

CVE-2020-16092

    A triggerable assert in the e1000e and vmxnet3 devices may result in
