Hello,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.
Upstream patch: --------------- -> https://lists.gnu.org/archive/html/qemu-devel/2016-09/msg07143.html This issue was reported by Li Qiang of 360.cn Inc. Thank you. -- Prasad J Pandit / Red Hat Product Security Team 47AF CE69 3A90 54AA 9045 1053 DD13 3D32 FE5B 041F
