It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2023-387 advisory.

  - In PostgreSQL, a modified, unauthenticated server can send an unterminated string during the establishment     of Kerberos transport encryption. In certain conditions a server can cause a libpq client to over-read and     report an error message containing uninitialized bytes. (CVE-2022-41862)

  - Row security policies disregard user ID changes after inlining; PostgreSQL could permit incorrect policies     to be applied in certain cases where role-specific policies are used and a given query is planned under     one role and then executed under other roles. This scenario can happen under security definer functions or     when a common user and query is planned initially and then re-used across multiple SET ROLEs. Applying an     incorrect policy may permit a user to complete otherwise-forbidden reads and modifications. This affects     only databases that have used CREATE POLICY to define a row security policy. (CVE-2023-2455)

  - A vulnerability was found in PostgreSQL with the use of the MERGE command, which fails to test new rows     against row security policies defined for UPDATE and SELECT. If UPDATE and SELECT policies forbid some     rows that INSERT policies do not forbid, a user could store such rows. (CVE-2023-39418)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
