The remote Ubuntu 16.04 LTS / 18.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-4390-1 advisory.

    It was discovered that the F2FS file system implementation in the Linux kernel did not properly perform     bounds checking on xattrs in some situations. A local attacker could possibly use this to expose sensitive     information (kernel memory). (CVE-2020-0067)

    It was discovered that memory contents previously stored in microarchitectural special registers after     RDRAND, RDSEED, and SGX EGETKEY read operations on Intel client and Xeon E3 processors may be briefly     exposed to processes on the same or different processor cores. A local attacker could use this to expose     sensitive information. (CVE-2020-0543)

    Piotr Krysiuk discovered that race conditions existed in the file system implementation in the Linux     kernel. A local attacker could use this to cause a denial of service (system crash). (CVE-2020-12114)

    It was discovered that the USB susbsystem's scatter-gather implementation in the Linux kernel did not     properly take data references in some situations, leading to a use-after-free. A physically proximate     attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code.
    (CVE-2020-12464)

    Xiumei Mu discovered that the IPSec implementation in the Linux kernel did not properly encrypt IPv6     traffic in some situations. An attacker could use this to expose sensitive information. (CVE-2020-1749)

    Dmitry Vyukov discovered that the SELinux netlink security hook in the Linux kernel did not validate     messages in some situations. A privileged attacker could use this to bypass SELinux netlink restrictions.
    (CVE-2020-10751)

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.
