"The remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has postgresql packages installed that are
affected by a vulnerability:

  - A flaw was found in postgresql in versions before 13.3, before 12.7, before 11.12, before 10.17 and before
    9.6.22. While modifying certain SQL array values, missing bounds checks let authenticated database users
    write arbitrary bytes to a wide area of server memory. The highest threat from this vulnerability is to
    data confidentiality and integrity as well as system availability. (CVE-2021-32027)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
