CVE-2020-14364

Priority
Description
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.
