From ${URL} : Quick Emulator(Qemu) built with the VirtFS, host directory sharing via Plan 9 File System(9pfs) support, is vulnerable to memory leakage issue. It could occur via its '9p-handle' or '9p-proxy' backend drivers as they do not free their respective allocated data objects. A privileged user inside guest could use this flaw to leak host memory, thus affecting other services on the host and/or potentially crash the Qemu process on the host. Upstream patches: ----------------- -> https://lists.gnu.org/archive/html/qemu-devel/2016-11/msg03278.html @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.
