CVE-2017-9375 [HIGH] QEMU regression
Title: QEMU regression
Summary: USN-3414-1 introduced a regression in QEMU.
USN-3414-1 fixed vulnerabilities in QEMU. The patch backport for
CVE-2017-9375 was incomplete and caused a regression in the USB xHCI
controller emulation support. This update fixes the problem.
We apologize for the inconvenience.
Original advisory details:
Leo Gaspard discovered that QEMU incorrectly handled VirtFS access control.
A guest attacker could use this issue to elevate privileges inside the
guest. (CVE-2017-7493)
Li Qiang discovered that QEMU incorrectly handled VMWare PVSCSI emulation.
A privileged attacker inside the guest could use this issue to cause QEMU
to consume resources or crash, resulting in a denial of service.

CVE-2017-9374 Qemu: usb: ehci host memory leakage during hotunplug
Quick Emulator(Qemu) built with the USB EHCI Emulation support is vulnerable
to a memory leakage issue. It could occur while hotunplugging the device, as
it does not release the memory allocated at initialisation.
A guest user/process could use this issue to leak host memory, resulting in
DoS for host.
