Echo: postgresql-13: security update to 13.11

medium Tenable Cloud Security Plugin ID 462399

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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)

Solution

Update the postgresql-13 library and its related packages to version 13.11 or later.
