prior to 15.8, or 16 prior to 16.4. As such, it is potentially affected by a vulnerability :

  - Time-of-check Time-of-use (TOCTOU) race condition in pg_dump in PostgreSQL allows an object creator to
    execute arbitrary SQL functions as the user running pg_dump, which is often a superuser. The attack
    involves replacing another relation type with a view or foreign table. The attack requires waiting for
    pg_dump to start, but winning the race condition is trivial if the attacker retains an open transaction.
    Versions before PostgreSQL 16.4, 15.8, 14.13, 13.16, and 12.20 are affected. (CVE-2024-7348)

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