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

    2024-02-29: CVE-2022-41862 was added to this 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)

    While CVE-2016-2193 fixed most interaction between row security and user ID changes, it missed a scenario     involving function inlining. This leads to potentially incorrect policies being applied in 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)

Tenable has extracted the preceding description block directly from the tested product security advisory.

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