Description Prasad Pandit 2016-05-24 09:16:13 UTC
Quick Emulator(Qemu) built with the LSI SAS1068 Host Bus Adapter emulation
support is vulnerable to an infinite loop issue. It could occur while fetching
new requests in mptsas_fetch_requests().

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