[] Quick Emulator(Qemu) built with the virtual hardware watchdog 'wdt_i6300esb' support is vulnerable to a memory leakage issue. It could occur while doing a 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 and/or potentially crash the Qemu process on the host. https://lists.nongnu.org/archive/html/qemu-devel/2016-12/msg03104.html https://bugzilla.redhat.com/show_bug.cgi?id=1415199 http://git.qemu.org/?p=qemu.git;a=commit;h=eb7a20a3616085d46aa6b4b4224e15587ec67e6e
