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

  - A flaw was discovered in postgresql versions 9.4.x before 9.4.24, 9.5.x before 9.5.19, 9.6.x before
    9.6.15, 10.x before 10.10 and 11.x before 11.5 where arbitrary SQL statements can be executed given a
    suitable SECURITY DEFINER function. An attacker, with EXECUTE permission on the function, can execute
    arbitrary SQL as the owner of the function. (CVE-2019-10208)

  - A flaw was found in PostgreSQL versions before 13.1, before 12.5, before 11.10, before 10.15, before
    9.6.20 and before 9.5.24. If a client application that creates additional database connections only reuses
    the basic connection parameters while dropping security-relevant parameters, an opportunity for a man-in-
    the-middle attack, or the ability to observe clear-text transmissions, could exist. The highest threat
    from this vulnerability is to data confidentiality and integrity as well as system availability.
    (CVE-2020-25694)

  - A flaw was found in PostgreSQL versions before 13.1, before 12.5, before 11.10, before 10.15, before
    9.6.20 and before 9.5.24. An attacker having permission to create non-temporary objects in at least one
    schema can execute arbitrary SQL functions under the identity of a superuser. The highest threat from this
    vulnerability is to data confidentiality and integrity as well as system availability. (CVE-2020-25695)

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