The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - In the Android kernel in F2FS touch driver there is a possible out of bounds read due to improper input     validation. This could lead to local information disclosure with system execution privileges needed. User     interaction is not needed for exploitation. (CVE-2019-9453)

Note that Nessus relies on the presence of the package as reported by the vendor.

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.
