| 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.
