How to fix?

NVD Description

Note: Versions mentioned in the description apply only to the upstream postgresql-16 package and not the postgresql-16 package as distributed by Ubuntu. See How to fix? for Ubuntu:24.04 relevant fixed versions and status.

Observable response discrepancy in PostgreSQL SCRAM authentication allows an unauthenticated user to test the existence of a user via observing the SCRAM iteration count. This requires the probed user to have a non-default scram_iterations count, because the authentication challenge for a nonexistent user reports the default scram_iterations. Within major versions 16-18, minor versions before PostgreSQL 18.6, 17.11, and 16.15 are affected. Versions before PostgreSQL 16 are unaffected.
