The remote Ubuntu 14.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-3932-2 advisory.

    USN-3932-1 fixed vulnerabilities in the Linux kernel for Ubuntu 16.04 LTS. This update provides the     corresponding updates for the Linux Hardware Enablement (HWE) kernel from Ubuntu 16.04 LTS for Ubuntu     14.04 LTS.

    It was discovered that a race condition existed in the f2fs file system implementation in the Linux     kernel. A local attacker could use this to cause a denial of service. (CVE-2017-18249)

    Wen Xu discovered that the f2fs file system implementation in the Linux kernel did not properly validate     metadata. An attacker could use this to construct a malicious f2fs image that, when mounted, could cause a     denial of service (system crash). (CVE-2018-13097, CVE-2018-13099, CVE-2018-13100, CVE-2018-14614,     CVE-2018-14616)

    Wen Xu and Po-Ning Tseng discovered that btrfs file system implementation in the Linux kernel did not     properly validate metadata. An attacker could use this to construct a malicious btrfs image that, when     mounted, could cause a denial of service (system crash). (CVE-2018-14610, CVE-2018-14611, CVE-2018-14612,     CVE-2018-14613)

    Vasily Averin and Evgenii Shatokhin discovered that a use-after-free vulnerability existed in the NFS41+     subsystem when multiple network namespaces are in use. A local attacker in a container could use this to     cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2018-16884)

    It was discovered that a use-after-free vulnerability existed in the PPP over L2TP implementation in the     Linux kernel. A privileged local attacker could use this to possibly execute arbitrary code.
    (CVE-2018-9517)

    Shlomi Oberman, Yuli Shapiro, and Ran Menscher discovered an information leak in the Bluetooth     implementation of the Linux kernel. An attacker within Bluetooth range could use this to expose sensitive     information (kernel memory). (CVE-2019-3459, CVE-2019-3460)

    Jann Horn discovered that the KVM implementation in the Linux kernel contained a use-after-free     vulnerability. An attacker in a guest VM with access to /dev/kvm could use this to cause a denial of     service (guest VM crash). (CVE-2019-6974)

    Jim Mattson and Felix Wilhelm discovered a use-after-free vulnerability in the KVM subsystem of the Linux     kernel, when using nested virtual machines. A local attacker in a guest VM could use this to cause a     denial of service (system crash) or possibly execute arbitrary code in the host system. (CVE-2019-7221)

    Felix Wilhelm discovered that an information leak vulnerability existed in the KVM subsystem of the Linux     kernel, when nested virtualization is used. A local attacker could use this to expose sensitive     information (host system memory to a guest VM). (CVE-2019-7222)

    Jann Horn discovered that the mmap implementation in the Linux kernel did not properly check for the mmap     minimum address in some situations. A local attacker could use this to assist exploiting a kernel NULL     pointer dereference vulnerability. (CVE-2019-9213)

    Muyu Yu discovered that the CAN implementation in the Linux kernel in some situations did not properly     restrict the field size when processing outgoing frames. A local attacker with CAP_NET_ADMIN privileges     could use this to execute arbitrary code. (CVE-2019-3701)

    Vladis Dronov discovered that the debug interface for the Linux kernel's HID subsystem did not properly     validate passed parameters in some situations. A local privileged attacker could use this to cause a     denial of service (infinite loop). (CVE-2019-3819)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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