Subject: CVE request: Qemu: 9p: directory traversal flaw in 9p virtio
 backend

   Hello,

Quick Emulator(Qemu) built with the VirtFS, host directory sharing via Plan 9 
File System(9pfs) support, is vulnerable to a directory/path traversal issue. 
It could occur while creating or accessing files on a shared host directory.

A privileged user inside guest could use this flaw to access undue files on 
the host.
