From ${URL} : Quick Emulator(Qemu) built with the virtio-9p back-end support is vulnerable to a null pointer dereference issue. It could occur while doing an I/O vector unmarshalling operation in v9fs_iov_vunmarshal() routine. A privileged user/process inside guest could use this flaw to crash the Qemu process instance resulting in Dos. Upstream patch: --------------- -> https://lists.gnu.org/archive/html/qemu-devel/2016-09/msg07143.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.
