Description Adam Mariš 2016-06-14 11:16:02 EDT 
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.
