CVE-2016-4439
MEDIUM6.7

The esp_reg_write function in hw/scsi/esp.c in the 53C9X Fast SCSI Controller (FSC) support in QEMU does not properly check command buffer length, which allows local guest OS administrators to cause a denial of service (out-of-bounds write and QEMU process crash) or potentially execute arbitrary code on the QEMU host via unspecified vectors.

MEDIUM6.0

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.

CVE-2016-4454
MEDIUM6.0

The vmsvga_fifo_read_raw function in hw/display/vmware_vga.c in QEMU allows local guest OS administrators to obtain sensitive host memory information or cause a denial of service (QEMU process crash) by changing FIFO registers and issuing a VGA command, which triggers an out-of-bounds read.

CVE-2016-4952
MEDIUM6.0

QEMU (aka Quick Emulator), when built with VMWARE PVSCSI paravirtual SCSI bus emulation support, allows local guest OS administrators to cause a denial of service (out-of-bounds array access) via vectors related to the (1) PVSCSI_CMD_SETUP_RINGS or (2) PVSCSI_CMD_SETUP_MSG_RING SCSI command.
