===================================================
  Hello,

Quick Emulator(Qemu) built with the VirtFS, host directory sharing via Plan 9
File System(9pfs) support, is vulnerable to memory leakage issue. It could
occur via its '9p-handle' or '9p-proxy' backend drivers as they do not free
their respective allocated data objects.


A privileged user inside guest could use this flaw to leak host memory, thus
affecting other services on the host and/or potentially crash the Qemu process
on the host.
