Description Prasad J Pandit 2017-04-26 03:13:45 EDT 
Quick Emulator(Qemu) built with the VMWARE PVSCSI paravirtual SCSI bus
emulation support is vulnerable to an infinite loop issue.
It could occur while initialising SCSI message ring buffer in pvscsi_log2().

A privileged user inside guest could use this flaw to consume host cpu cycles
or crash the Qemu process resulting in DoS.
