The remote Ubuntu 16.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-3910-1 advisory.

    It was discovered that the f2fs filesystem implementation in the Linux kernel did not handle the     noflush_merge mount option correctly. An attacker could use this to cause a denial of service (system     crash). (CVE-2017-18241)

    It was discovered that the procfs filesystem did not properly handle processes mapping some memory     elements onto files. A local attacker could use this to block utilities that examine the procfs filesystem     to report operating system state, such as ps(1). (CVE-2018-1120)

    Hui Peng and Mathias Payer discovered that the Option USB High Speed driver in the Linux kernel did not     properly validate metadata received from the device. A physically proximate attacker could use this to     cause a denial of service (system crash). (CVE-2018-19985)

    It was discovered that multiple integer overflows existed in the hugetlbfs implementation in the Linux     kernel. A local attacker could use this to cause a denial of service (system crash). (CVE-2018-7740)

    Jann Horn discovered a race condition in the fork() system call in the Linux kernel. A local attacker     could use this to gain access to services that cache authorizations. (CVE-2019-6133)

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.
