The remote Ubuntu 14.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-3821-2 advisory.

    USN-3821-1 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.

    Wen Xu discovered that the ext4 filesystem implementation in the Linux kernel did not properly ensure that     xattr information remained in inode bodies. An attacker could use this to construct a malicious ext4 image     that, when mounted, could cause a denial of service (system crash). (CVE-2018-10880)

    It was discovered that the alarmtimer implementation in the Linux kernel contained an integer overflow     vulnerability. A local attacker could use this to cause a denial of service. (CVE-2018-13053)

    Wen Xu discovered that the f2fs filesystem 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-2018-13096)

    Wen Xu and Po-Ning Tseng discovered that the btrfs filesystem implementation in the Linux kernel did not     properly handle relocations in some situations. An attacker could use this to construct a malicious btrfs     image that, when mounted, could cause a denial of service (system crash). (CVE-2018-14609)

    Wen Xu discovered that the HFS+ filesystem implementation in the Linux kernel did not properly handle     malformed catalog data in some situations. An attacker could use this to construct a malicious HFS+ image     that, when mounted, could cause a denial of service (system crash). (CVE-2018-14617)

    Jann Horn discovered that the procfs file system implementation in the Linux kernel did not properly     restrict the ability to inspect the kernel stack of an arbitrary task. A local attacker could use this to     expose sensitive information. (CVE-2018-17972)

    It was discovered that the KVM implementation in the Linux kernel on ARM 64bit processors did not properly     handle some ioctls. An attacker with the privilege to create KVM-based virtual machines could use this to     cause a denial of service (host system crash) or execute arbitrary code in the host. (CVE-2018-18021)

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.
