The remote Ubuntu 16.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-4419-1 advisory.

    It was discovered that a race condition existed in the Precision Time Protocol (PTP) implementation in the     Linux kernel, leading to a use-after- free vulnerability. A local attacker could possibly use this to     cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2020-10690)

    Matthew Sheets discovered that the SELinux network label handling implementation in the Linux kernel could     be coerced into de-referencing a NULL pointer. A remote attacker could use this to cause a denial of     service (system crash). (CVE-2020-10711)

    It was discovered that the SCSI generic (sg) driver in the Linux kernel did not properly handle certain     error conditions correctly. A local privileged attacker could use this to cause a denial of service     (system crash). (CVE-2020-12770)

    It was discovered that the USB Gadget device driver in the Linux kernel did not validate arguments passed     from configfs in some situations. A local attacker could possibly use this to cause a denial of service     (system crash) or possibly expose sensitive information. (CVE-2020-13143)

    Shijie Luo discovered that the ext4 file system implementation in the Linux kernel did not properly check     for a too-large journal size. An attacker could use this to construct a malicious ext4 image that, when     mounted, could cause a denial of service (soft lockup). (CVE-2020-8992)

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.
