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-2017-8112)

 It was discovered that QEMU incorrectly handled MegaRAID SAS 8708EM2 Host
 Bus Adapter emulation support. A privileged attacker inside the guest could
 use this issue to cause QEMU to crash, resulting in a denial of service, or
 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)

 Li Qiang discovered that QEMU incorrectly handled IDE AHCI emulation
 support. A privileged attacker inside the guest could use this issue to
 cause QEMU to consume resources and crash, resulting in a denial of
 service. (CVE-2017-9373)

 Li Qiang discovered that QEMU incorrectly handled USB EHCI emulation
 support. A privileged attacker inside the guest could use this issue to
 cause QEMU to consume resources and crash, resulting in a denial of
 service. (CVE-2017-9374)

 Li Qiang discovered that QEMU incorrectly handled USB xHCI emulation
 support. A privileged attacker inside the guest could use this issue to
 cause QEMU to hang, resulting in a denial of service. (CVE-2017-9375)

 Zhangyanyu discovered that QEMU incorrectly handled MegaRAID SAS 8708EM2
 Host Bus Adapter emulation support. A privileged attacker inside the guest
 could use this issue to cause QEMU to crash, resulting in a denial of
 service. (CVE-2017-9503)

 It was discovered that the QEMU qemu-nbd server incorrectly handled
 initialization. A remote attacker could use this issue to cause the server
 to crash, resulting in a denial of service. (CVE-2017-9524)

 It was discovered that the QEMU ... [Please see the references for more information on the vulnerabilities]");
