affects qemu < 2.7.0 Quick Emulator(Qemu) built with the ESP/NCR53C9x controller emulation support is vulnerable to an OOB write access issue. The controller uses 16-byte FIFO buffer for command and data transfer. The OOB write occurs while writing to this command buffer in routine get_cmd(). A privileged user inside guest could use this flaw to crash the Qemu process resulting in DoS.
