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 qemu-nbd server incorrectly handled signals. A remote attacker could use this issue to cause the server to crash, resulting in a denial of service. (CVE-2017-10664) Li Qiang discovered that the QEMU USB redirector incorrectly handled logging debug messages. An attacker inside the guest could use this issue to cause QEMU to crash, resulting in a denial of service. (CVE-2017-10806) Anthony Perard discovered that QEMU incorrectly handled Xen block-interface responses. An attacker inside the guest could use this issue to cause QEMU to leak contents of host memory. (CVE-2017-10911) Reno Robert discovered that QEMU incorrectly handled certain DHCP options strings. An attacker inside the guest could use this issue to cause QEMU to crash, resulting in a denial of service. (CVE-2017-11434) Ryan Salsamendi discovered that QEMU incorrectly handled empty CDROM device drives. A privileged attacker inside the guest could use this issue to cause QEMU to crash, resulting in a denial of service. This issue only affected Ubuntu 16.04 LTS and Ubuntu 17.04. (CVE-2017-12809).
