The remote Ubuntu 14.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-3776-2 advisory.

    USN-3776-1 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.

    Jann Horn discovered that the vmacache subsystem did not properly handle sequence number overflows,     leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service     (system crash) or execute arbitrary code. (CVE-2018-17182)

    It was discovered that the paravirtualization implementation in the Linux kernel did not properly handle     some indirect calls, reducing the effectiveness of Spectre v2 mitigations for paravirtual guests. A local     attacker could use this to expose sensitive information. (CVE-2018-15594)

    It was discovered that microprocessors utilizing speculative execution and prediction of return addresses     via Return Stack Buffer (RSB) may allow unauthorized memory reads via sidechannel attacks. An attacker     could use this to expose sensitive information. (CVE-2018-15572)

    It was discovered that a NULL pointer dereference could be triggered in the OCFS2 file system     implementation in the Linux kernel. A local attacker could use this to cause a denial of service (system     crash). (CVE-2017-18216)

    It was discovered that a race condition existed in the raw MIDI driver for the Linux kernel, leading to a     double free vulnerability. A local attacker could use this to cause a denial of service (system crash) or     possibly execute arbitrary code. (CVE-2018-10902)

    It was discovered that a stack-based buffer overflow existed in the iSCSI target implementation of the     Linux kernel. A remote attacker could use this to cause a denial of service (system crash).
    (CVE-2018-14633)

    It was discovered that the YUREX USB device driver for the Linux kernel did not properly restrict user     space reads or writes. A physically proximate attacker could use this to cause a denial of service (system     crash) or possibly execute arbitrary code. (CVE-2018-16276)

    It was discovered that a memory leak existed in the IRDA subsystem of the Linux kernel. A local attacker     could use this to cause a denial of service (kernel memory exhaustion). (CVE-2018-6554)

    It was discovered that a use-after-free vulnerability existed in the IRDA implementation in the Linux     kernel. A local attacker could use this to cause a denial of service (system crash) or possibly execute     arbitrary code. (CVE-2018-6555)

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.
