"The remote Rocky Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the
RLSA-2023:3714 advisory.

  - schema_element defeats protective search_path changes; It was found that certain database calls in
    PostgreSQL could permit an authed attacker with elevated database-level privileges to execute arbitrary
    code. (CVE-2023-2454)

  - 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)

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