From ${URL} : Quick Emulator(Qemu) built with the USB xHCI controller emulation support is vulnerable to a memory leakage issue. It could occur while doing a USB device unplug operation; 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 instance on the host. Upstream patch: --------------- -> https://lists.gnu.org/archive/html/qemu-devel/2016-09/msg02773.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.
