A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 17.04 - Ubuntu 16.04 LTS - Ubuntu 14.04 LTS

Summary:

Several security issues were fixed in QEMU.

Software Description: - qemu: Machine emulator and virtualizer

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 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)
