Description Agostino Sarubbo gentoo-dev 2016-05-24 10:41:28 UTC
From ${URL} :

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.

Upstream patch:

This issue was discovered and reported by Li Qiang of Inc.

@maintainer(s): after the bump, in case we need to stabilize the package, please let us know if it is ready for the stabilization or not.
