The remote Ubuntu 16.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-3361-1 advisory.

  - The VFS subsystem in the Linux kernel 3.x provides an incomplete set of requirements for setattr     operations that underspecifies removing extended privilege attributes, which allows local users to cause a     denial of service (capability stripping) via a failed invocation of a system call, as demonstrated by     using chown to remove a capability from the ping or Wireshark dumpcap program. (CVE-2015-1350)

  - The ext4_fill_super function in fs/ext4/super.c in the Linux kernel through 4.9.8 does not properly     validate meta block groups, which allows physically proximate attackers to cause a denial of service (out-     of-bounds read and system crash) via a crafted ext4 image. (CVE-2016-10208)

  - An information disclosure vulnerability in kernel components including the ION subsystem, Binder, USB     driver and networking subsystem could enable a local malicious application to access data outside of its     permission levels. This issue is rated as Moderate because it first requires compromising a privileged     process. Product: Android. Versions: Kernel-3.10, Kernel-3.18. Android ID: A-31651010. (CVE-2016-8405)

  - Integer overflow in the mem_check_range function in drivers/infiniband/sw/rxe/rxe_mr.c in the Linux kernel     before 4.9.10 allows local users to cause a denial of service (memory corruption), obtain sensitive     information from kernel memory, or possibly have unspecified other impact via a write or read request     involving the RDMA protocol over infiniband (aka Soft RoCE) technology. (CVE-2016-8636)

  - 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)

  - The cgroup offline implementation in the Linux kernel through 4.8.11 mishandles certain drain operations,     which allows local users to cause a denial of service (system hang) by leveraging access to a container     environment for executing a crafted application, as demonstrated by trinity. (CVE-2016-9191)

  - 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 netfilter subsystem in the Linux kernel before 4.9 mishandles IPv6 reassembly, which allows local     users to cause a denial of service (integer overflow, out-of-bounds write, and GPF) or possibly have     unspecified other impact via a crafted application that makes socket, connect, and writev system calls,     related to net/ipv6/netfilter/nf_conntrack_reasm.c and net/ipv6/netfilter/nf_defrag_ipv6_hooks.c.
    (CVE-2016-9755)

  - The load_segment_descriptor implementation in arch/x86/kvm/emulate.c in the Linux kernel before 4.9.5     improperly emulates a MOV SS, NULL selector instruction, which allows guest OS users to cause a denial     of service (guest OS crash) or gain guest OS privileges via a crafted application.
