Description Agostino Sarubbo gentoo-dev 2017-04-05 10:42:36 UTC
From ${URL} :

Quick Emulator(Qemu) built with the virtio-9p back-end support is vulnerable
to a memory leakage issue. It could occur while doing a I/O operation via
v9fs_create/v9fs_lcreate routine.

A privileged user/process inside guest could use this flaw to leak host memory
resulting in Dos.
