[] 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.

http://git.qemu.org/?p=qemu.git;a=commit;h=eb7a20a3616085d46aa6b4b4224e15587ec67e6e

Use CVE-2016-10155 for this (i.e., a memory consumption issue, not an
information disclosure issue).
