Description Agostino Sarubbo gentoo-dev 2016-10-10 13:21:33 UTC 
From ${URL} :

Quick Emulator(Qemu) built with the virtio-9p back-end support is vulnerable 
to a null pointer dereference issue. It could occur while doing an I/O vector 
unmarshalling operation in v9fs_iov_vunmarshal() routine.

A privileged user/process inside guest could use this flaw to crash the Qemu 
process instance resulting in Dos.
