The weakness is caused due to a boundary error within the "scsi_disk_emulate_command()" function (hw/scsi-disk.c) of the SCSI subsystem and can be exploited to cause a buffer overflow and crash a guest by e.g. sending a specially crafted "READ CAPACITY" command. SOLUTION: Restrict access to trusted users. PROVIDED AND/OR DISCOVERED BY: Red Hat credits Paolo Bonzini.
