From ${URL} : Quick Emulator(Qemu) built with the keyboard input event handlers support is vulnerable to a host memory leakage issue. It could occur if a guest user was to generate large keyboard events, faster than Qemu could process them. A privileged user inside guest could use this flaw to exhaust host memory, resulting in DoS. Upstream patch: --------------- -> https://lists.gnu.org/archive/html/qemu-devel/2017-04/msg05599.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.
