The remote Ubuntu 16.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-4527-1 advisory.

    It was discovered that the Conexant 23885 TV card device driver for the Linux kernel did not properly     deallocate memory in some error conditions. A local attacker could use this to cause a denial of service     (memory exhaustion). (CVE-2019-19054)

    It was discovered that the Atheros HTC based wireless driver in the Linux kernel did not properly     deallocate in certain error conditions. A local attacker could use this to cause a denial of service     (memory exhaustion). (CVE-2019-19073, CVE-2019-19074)

    Yue Haibing discovered that the Linux kernel did not properly handle reference counting in sysfs for     network devices in some situations. A local attacker could possibly use this to cause a denial of service.
    (CVE-2019-20811)

    It was discovered that the F2FS file system in the Linux kernel did not properly perform bounds checking     in some situations, leading to an out-of- bounds read. A local attacker could possibly use this to expose     sensitive information (kernel memory). (CVE-2019-9445)

    It was discovered that the F2FS file system in the Linux kernel did not properly validate xattr meta data     in some situations, leading to an out-of- bounds read. An attacker could use this to construct a malicious     F2FS image that, when mounted, could expose sensitive information (kernel memory). (CVE-2019-9453)

    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 the NFS client implementation in the Linux kernel did not properly perform bounds     checking before copying security labels in some situations. A local attacker could use this to cause a     denial of service (system crash) or possibly execute arbitrary code. (CVE-2020-25212)

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.
