UBUNTU-CVE-2015-6855

hw/ide/core.c in QEMU does not properly restrict the commands accepted by an ATAPI device, which allows guest users to cause a denial of service or possibly have unspecified other impact via certain IDE commands, as demonstrated by a WINREADNATIVE_MAX command to an empty drive, which triggers a divide-by-zero error and instance crash.
