The remote Ubuntu 16.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-3312-1 advisory.

  - The xc2028_set_config function in drivers/media/tuners/tuner-xc2028.c in the Linux kernel before 4.6     allows local users to gain privileges or cause a denial of service (use-after-free) via vectors involving     omission of the firmware name from a certain data structure. (CVE-2016-7913)

  - The nfnetlink_rcv_batch function in net/netfilter/nfnetlink.c in the Linux kernel before 4.5 does not     check whether a batch message's length field is large enough, which allows local users to obtain sensitive     information from kernel memory or cause a denial of service (infinite loop or out-of-bounds read) by     leveraging the CAP_NET_ADMIN capability. (CVE-2016-7917)

  - The tipc_msg_build function in net/tipc/msg.c in the Linux kernel through 4.8.11 does not validate the     relationship between the minimum fragment length and the maximum packet size, which allows local users to     gain privileges or cause a denial of service (heap-based buffer overflow) by leveraging the CAP_NET_ADMIN     capability. (CVE-2016-8632)

  - drivers/vfio/pci/vfio_pci.c in the Linux kernel through 4.8.11 allows local users to bypass integer     overflow checks, and cause a denial of service (memory corruption) or have unspecified other impact, by     leveraging access to a vfio PCI device file for a VFIO_DEVICE_SET_IRQS ioctl call, aka a state machine     confusion bug. (CVE-2016-9083)

  - drivers/vfio/pci/vfio_pci_intrs.c in the Linux kernel through 4.8.11 misuses the kzalloc function, which     allows local users to cause a denial of service (integer overflow) or have unspecified other impact by     leveraging access to a vfio PCI device file. (CVE-2016-9084)

  - It was discovered in the Linux kernel before 4.11-rc8 that root can gain direct access to an internal     keyring, such as '.dns_resolver' in RHEL-7 or '.builtin_trusted_keys' upstream, by joining it as its     session keyring. This allows root to bypass module signature verification by adding a new public key of     its own devising to the keyring. (CVE-2016-9604)

  - The nested_vmx_check_vmptr function in arch/x86/kvm/vmx.c in the Linux kernel through 4.9.8 improperly     emulates the VMXON instruction, which allows KVM L1 guest OS users to cause a denial of service (host OS     memory consumption) by leveraging the mishandling of page references. (CVE-2017-2596)

  - The ping_unhash function in net/ipv4/ping.c in the Linux kernel through 4.10.8 is too late in obtaining a     certain lock and consequently cannot ensure that disconnect function calls are safe, which allows local     users to cause a denial of service (panic) by leveraging access to the protocol value of IPPROTO_ICMP in a     socket system call. (CVE-2017-2671)

  - Race condition in kernel/events/core.c in the Linux kernel before 4.9.7 allows local users to gain     privileges via a crafted application that makes concurrent perf_event_open system calls for moving a     software group into a hardware context. NOTE: this vulnerability exists because of an incomplete fix for     CVE-2016-6786. (CVE-2017-6001)

  - The KEYS subsystem in the Linux kernel before 4.10.13 allows local users to cause a denial of service     (memory consumption) via a series of KEY_REQKEY_DEFL_THREAD_KEYRING keyctl_set_reqkey_keyring calls.
    (CVE-2017-7472)

  - crypto/ahash.c in the Linux kernel through 4.10.9 allows attackers to cause a denial of service (API     operation calling its own callback, and infinite recursion) by triggering EBUSY on a full queue.
    (CVE-2017-7618)

  - The NFSv2/NFSv3 server in the nfsd subsystem in the Linux kernel through 4.10.11 allows remote attackers     to cause a denial of service (system crash) via a long RPC reply, related to net/sunrpc/svc.c,     fs/nfsd/nfs3xdr.c, and fs/nfsd/nfsxdr.c. (CVE-2017-7645)

  - The mm subsystem in the Linux kernel through 3.2 does not properly enforce the CONFIG_STRICT_DEVMEM     protection mechanism, which allows local users to read or write to kernel memory locations in the first     megabyte (and bypass slab-allocation access restrictions) via an application that opens the /dev/mem file,     related to arch/x86/mm/init.c and drivers/char/mem.c. (CVE-2017-7889)

  - The NFSv2 and NFSv3 server implementations in the Linux kernel through 4.10.13 lack certain checks for the     end of a buffer, which allows remote attackers to trigger pointer-arithmetic errors or possibly have     unspecified other impact via crafted requests, related to fs/nfsd/nfs3xdr.c and fs/nfsd/nfsxdr.c.
    (CVE-2017-7895)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
