The remote Ubuntu 16.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-3055-1 advisory.

    Ben Hawkes discovered an integer overflow in the Linux netfilter implementation. On systems running 32 bit     kernels, a local unprivileged attacker could use this to cause a denial of service (system crash) or     possibly execute arbitrary code with administrative privileges. (CVE-2016-3135)

    It was discovered that the keyring implementation in the Linux kernel did not ensure a data structure was     initialized before referencing it after an error condition occurred. A local attacker could use this to     cause a denial of service (system crash). (CVE-2016-4470)

    Sasha Levin discovered that a use-after-free existed in the percpu allocator in the Linux kernel. A local     attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code     with administrative privileges. (CVE-2016-4794)

    Kangjie Lu discovered an information leak in the netlink implementation of the Linux kernel. A local     attacker could use this to obtain sensitive information from kernel memory. (CVE-2016-5243)

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.
