The remote Ubuntu 14.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-3470-1 advisory.

  - 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)

  - Race condition in fs/timerfd.c in the Linux kernel before 4.10.15 allows local users to gain privileges or     cause a denial of service (list corruption or use-after-free) via simultaneous file-descriptor operations     that leverage improper might_cancel queueing. (CVE-2017-10661)

  - The sanity_check_raw_super function in fs/f2fs/super.c in the Linux kernel before 4.11.1 does not validate     the segment count, which allows local users to gain privileges via unspecified vectors. (CVE-2017-10662)

  - The sanity_check_ckpt function in fs/f2fs/super.c in the Linux kernel before 4.12.4 does not validate the     blkoff and segno arrays, which allows local users to gain privileges via unspecified vectors.
    (CVE-2017-10663)

  - The make_response function in drivers/block/xen-blkback/blkback.c in the Linux kernel before 4.11.8 allows     guest OS users to obtain sensitive information from host OS (or other guest OS) kernel memory by     leveraging the copying of uninitialized padding fields in Xen block-interface response structures, aka     XSA-216. (CVE-2017-10911)

  - The mq_notify function in the Linux kernel through 4.11.9 does not set the sock pointer to NULL upon entry     into the retry logic. During a user-space close of a Netlink socket, it allows attackers to cause a denial     of service (use-after-free) or possibly have unspecified other impact. (CVE-2017-11176)

  - The XFS_IS_REALTIME_INODE macro in fs/xfs/xfs_linux.h in the Linux kernel before 4.13.2 does not verify     that a filesystem has a realtime device, which allows local users to cause a denial of service (NULL     pointer dereference and OOPS) via vectors related to setting an RHINHERIT flag on a directory.
    (CVE-2017-14340)

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