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)

CVE-2017-9503 Qemu: scsi: megasas: null pointer dereference while processing megasas command
Quick Emulator(Qemu) built with the MegaRAID SAS 8708EM2 Host Bus Adapter
emulation support is vulnerable to a null pointer dereference issue. It
could occur while processing megasas commands via megasas_command_complete().
A privileged user inside guest could use this flaw to crash the Qemu process
on the host resulting in DoS.
