The remote Ubuntu 18.04 ESM host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6538-2 advisory.

    USN-6538-1 fixed several vulnerabilities in PostgreSQL. This update provides the corresponding updates for     Ubuntu 18.04 LTS.

    Original advisory details:

    Jingzhou Fu discovered that PostgreSQL incorrectly handled certain unknown

    arguments in aggregate function calls. A remote attacker could possibly use

    this issue to obtain sensitive information. (CVE-2023-5868)

    Pedro Gallegos discovered that PostgreSQL incorrectly handled modifying

    certain SQL array values. A remote attacker could use this issue to obtain

    sensitive information, or possibly execute arbitrary code. (CVE-2023-5869)

    Hemanth Sandrana and Mahendrakar Srinivasarao discovered that PostgreSQL

    allowed the pg_signal_backend role to signal certain superuser processes,

    contrary to expectations. (CVE-2023-5870)

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.
