Descriptions

The serial_update_parameters function in hw/char/serial.c in QEMU (aka Quick Emulator) allows local guest OS administrators to cause a denial of service (divide-by-zero error and QEMU process crash) via vectors involving a value of divider greater than baud base.

La función serial_update_parameters en hw/char/serial.c en QEMU (también conocido como Quick Emulator) permite a administradores locales del SO invitado provocar una denegación de servicio (error de división por cero y caída del proceso QEMU) a través de vectores que involucran un valor de divisor mayor que la base baud.
