Title: QEMU vulnerabilities
Summary: Several security issues were fixed in QEMU.
Li Qiang discovered that QEMU incorrectly handled VirtFS directory sharing.
A privileged attacker inside the guest could use this issue to cause QEMU
to crash, resulting in a denial of service. (CVE-2017-7377, CVE-2017-8086)
Jiangxin discovered that QEMU incorrectly handled the Cirrus VGA device. A
privileged attacker inside the guest could use this issue to cause QEMU to
crash, resulting in a denial of service. (CVE-2017-7718)
Li Qiang and Jiangxin discovered that QEMU incorrectly handled the Cirrus
VGA device when being used with a VNC connection. A privileged attacker
inside the guest could use this issue to cause QEMU to crash, resulting in
a denial of service, or possibly execute arbitrary code on the

CVE-2017-8086 Qemu: 9pfs: host memory leakage via v9pfs_list_xattr
Quick Emulator(Qemu) built with the virtio-9p back-end support is vulnerable
to a memory leakage issue. It could occur while querying file system extended
attributes via 9pfs_list_xattr() routine.
A privileged user/process inside guest could use this flaw to leak host memory
resulting in Dos.
