QEMU < 2.6.0 - Denial of Service via SCSI Controller DMA Length Check

Title source: llm
STIX 2.1

Description

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.
