Description Victor Pereira 2016-09-08 09:27:32 UTC 
rh#1373504

Quick emulator(Qemu) built with the LSI SAS1068 Host Bus emulation support,
is vulnerable to an invalid memory access issue. It could occur while building
configuration page headers in 'mptsas_config_manufacturing_1'.

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