QEMU is vulnerable to denial of service(DoS) through divide by zero attacks. This occurs in the serial_update_parameters function in hw/char/serial.c which allows local guest OS administrators to cause divide-by-zero error and QEMU process crash via vectors involving a value of divider greater than baud base.
