The get_cmd function in hw/scsi/esp.c in the 53C9X Fast SCSI Controller (FSC) support in QEMU does not properly check DMA length, which allows local guest OS administrators to cause a denial of service (out-of-bounds write and QEMU process crash) via unspecified vectors, involving an SCSI command.

issue to cause QEMU to crash, resulting in a denial of service, or possibly

is used with libvirt, attackers would be isolated by the libvirt AppArmor
profile. This issue only applied to Ubuntu 14.04 LTS and Ub

CVE-2016-4441 Qemu: scsi: esp: OOB write while writing to 's->cmdbuf' in get_cmd
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.
