Ubuntu Security Notice 3414-2 - 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. Leo Gaspard discovered that QEMU incorrectly handled VirtFS access control. A guest attacker could use this issue to elevate privileges inside the guest. 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. Various other issues were also addressed.
