"details": "Zuozhi Fzz discovered that QEMU incorrectly handled USB OHCI emulation\nsupport. A privileged attacker inside the guest could use this issue to\ncause QEMU to crash, resulting in a denial of service. (CVE-2016-2391)\n\nQinghao Tang discovered that QEMU incorrectly handled USB Net emulation\nsupport. A privileged attacker inside the guest could use this issue to\ncause QEMU to crash, resulting in a denial of service. (CVE-2016-2392)\n\nQinghao Tang discovered that QEMU incorrectly handled USB Net emulation\nsupport. A privileged attacker inside the guest could use this issue to\ncause QEMU to crash, resulting in a denial of service, or possibly leak\nhost memory bytes. (CVE-2016-2538)\n\nHongke Yang discovered that QEMU incorrectly handled NE2000 emulation\nsupport. A privileged attacker inside the guest could use this issue to\ncause QEMU to crash, resulting in a denial of service. (CVE-2016-2841)\n\nLing Liu discovered that QEMU incorrectly handled IP checksum routines. An\nattacker inside the guest could use this issue to cause QEMU to crash,\nresulting in a denial of service, or possibly leak host memory bytes.\n(CVE-2016-2857)\n\nIt was discovered that QEMU incorrectly handled the PRNG back-end support.\nAn attacker inside the guest could use this issue to cause QEMU to crash,\nresulting in a denial of service. This issue only applied to Ubuntu 14.04\nLTS, Ubuntu 15.10 and Ubuntu 16.04 LTS. (CVE-2016-2858)\n\nWei Xiao and Qinghao Tang discovered that QEMU incorrectly handled access\nin the VGA module. A privileged attacker inside the guest could use this\nissue to cause QEMU to crash, resulting in a denial of service, or possibly\nexecute arbitrary code on the host. In the default installation, when QEMU\nis used with libvirt, attackers would be isolated by the libvirt AppArmor\nprofile. (CVE-2016-3710)\n\nZuozhi Fzz discovered that QEMU incorrectly handled access in the VGA\nmodule. A privileged attacker inside the guest could use this issue to\ncause QEMU to crash, resulting in a denial of service, or possibly\nexecute arbitrary code on the host. In the default installation, when QEMU\nis used with libvirt, attackers would be isolated by the libvirt AppArmor\nprofile.

A remote attacker could use\nthis issue to cause QEMU to crash, resulting in a denial of service.\n(CVE-2016-4001)\n\nOleksandr Bazhaniuk discovered that QEMU incorrectly handled MIPSnet\ncontroller emulation. A remote attacker could use this issue to cause QEMU\nto crash, resulting in a denial of service. (CVE-2016-4002)\n\nDonghai Zdh discovered that QEMU incorrectly handled the Task Priority\nRegister(TPR). A privileged attacker inside the guest could use this issue\nto possibly leak host memory bytes. This issue only applied to Ubuntu 14.04\nLTS, Ubuntu 15.10 and Ubuntu 16.04 LTS. (CVE-2016-4020)\n\nDu Shaobo discovered that QEMU incorrectly handled USB EHCI emulation\nsupport. A privileged attacker inside the guest could use this issue to\ncause QEMU to consume resources, resulting in a denial of service.\n(CVE-2016-4037)\n",
