Ubuntu Security Notice USN-3414-2
September 20, 2017

qemu regression
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 17.04
- Ubuntu 16.04 LTS
- Ubuntu 14.04 LTS

Summary:

USN-3414-1 introduced a regression in QEMU.

Software Description:
- qemu: Machine emulator and virtualizer

Details:

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)

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-2017-8112)
It was discovered that QEMU incorrectly handled MegaRAID SAS 8708EM2 Host
Bus Adapter emulation support. A privileged attacker inside the guest could

possibly to obtain sensitive host memory. This issue only affected Ubuntu
16.04 LTS and Ubuntu 17.04. (CVE-2017-8380)
Li Qiang discovered that QEMU incorrectly handled the Virtio GPU device. An
attacker inside the guest could use this issue to cause QEMU to consume
resources and crash, resulting in a denial of service. This issue only
affected Ubuntu 17.04. (CVE-2017-9060)
Li Qiang discovered that QEMU incorrectly handled the e1000e device. A
privileged attacker inside the guest could use this issue to cause QEMU to
hang, resulting in a denial of service. This issue only affected Ubuntu
17.04. (CVE-2017-9310)
Li Qiang discovered that QEMU incorrectly handled USB OHCI emulation
support. An attacker inside the guest could use this issue to cause QEMU to
crash, resulting in a denial of service. (CVE-2017-9330)
