From ${URL} : Quick Emulator(Qemu) built with the i8255x (PRO100) NIC emulation support is vulnerable to a memory leakage issue. It could occur while unplugging the device, and doing so repeatedly would result in leaking host memory affecting, other services on the host. A privileged user inside guest could use this flaw to cause a DoS on the host and/or potentially crash the Qemu process on the host. Upstream patch: --------------- -> https://lists.gnu.org/archive/html/qemu-devel/2016-10/msg03024.html Reference: ---------- -> https://bugzilla.redhat.com/show_bug.cgi?id=1389538 This issue was reported by Li Qiang of 360.cn 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.
