The remote Ubuntu 16.04 ESM host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-6602-1 advisory.

    Jana Hofmann, Emanuele Vannacci, Cedric Fournet, Boris Kopf, and Oleksii Oleksenko discovered that some     AMD processors could leak stale data from division operations in certain situations. A local attacker     could possibly use this to expose sensitive information. (CVE-2023-20588)

    It was discovered that a race condition existed in the Linux kernel when performing operations with kernel     objects, leading to an out-of-bounds write. A local attacker could use this to cause a denial of service     (system crash) or execute arbitrary code. (CVE-2023-45863)

    It was discovered that the CIFS network file system implementation in the Linux kernel did not properly     validate the server frame size in certain situation, leading to an out-of-bounds read vulnerability. An     attacker could use this to construct a malicious CIFS image that, when operated on, could cause a denial     of service (system crash) or possibly expose sensitive information. (CVE-2023-6606)

    Budimir Markovic, Lucas De Marchi, and Pengfei Xu discovered that the perf subsystem in the Linux kernel     did not properly validate all event sizes when attaching new events, leading to an out-of-bounds write     vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly     execute arbitrary code. (CVE-2023-6931)

    It was discovered that the IGMP protocol implementation in the Linux kernel contained a race condition,     leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service     (system crash) or possibly execute arbitrary code. (CVE-2023-6932)

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.
