Echo: postgresql-15: security update to 15.19postgresql-17: security update to 17.11

medium Tenable Self-Hosted Container Security Plugin ID 465345

Description

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

 - Incomplete tracking in PostgreSQL of changes to role membership, role attributes, and database ownership
 allows a query to continue using cached row-level security policies after those changes require a
 different policy, via plan reuse. Stale policies continue until some other event invalidates the cache or
 connection termination ends the session. This permits a user to complete reads and modifications that were
 recently permitted but now forbidden. An attacker must tailor an attack to a particular application's
 pattern of privilege removal and role-specific row security policies. Versions before PostgreSQL 18.6,
 17.11, 16.15, 15.19, and 14.24 are affected. (CVE-2026-14666)

Solution

Update the postgresql-15 library and its related packages to version 15.19 or later.
