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-2017-8379 [MEDIUM] CVE-2017-8379 Qemu: input: host memory lekage via keyboard events
CVE-2017-8379 Qemu: input: host memory lekage via keyboard events
Quick Emulator(Qemu) built with the keyboard input event handlers support is
vulnerable to a host memory leakage issue. It could occur if a guest user was
to generate large keyboard events, faster than Qemu could process them.
A privileged user inside guest could use this flaw to exhaust host memory,
resulting in DoS.
