Quick Emulator(Qemu) built with the VirtFS, host directory sharing via Plan 9 
File System(9pfs) support, is vulnerable to an information leakage issue. It 
could occur by accessing xattribute value before it's written to.

A privileged user inside guest could use this flaw to leak host memory bytes.
