Description Prasad Pandit 2016-05-25 11:29:01 UTC 
Quick Emulator(Qemu) built with the MegaRAID SAS 8708EM2 Host Bus Adapter
emulation support is vulnerable to an out-of-bounds write access issue. It
could occur while processing MegaRAID Firmware Interface(MFI) command to set
controller properties in 'megasas_dcmd_set_properties'.

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