Quick Emulator(Qemu) built with the VMWARE PVSCSI paravirtual SCSI bus emulation support is vulnerable to an OOB r/w access issue. It could occur while processing SCSI commands ‘PVSCSI_CMD_SETUP_RINGS’ or ‘PVSCSI_CMD_SETUP_MSG_RING’. A privileged user inside guest could use this flaw to crash the Qemu process resulting in DoS.
