Description Agostino Sarubbo gentoo-dev 2016-09-19 14:54:53 UTC
From ${URL} :

Quick emulator(Qemu) built with the LSI SAS1068 Host Bus emulation support,
is vulnerable to an invalid memory access issue. It could occur while
processing scsi io requests in mptsas_process_scsi_io_request.

A privileged user inside guest could use this flaw to crash the Qemu process
instance on the host resulting in DoS.
