✅ Remediation

For details on how to apply this update, which includes the changes described in this advisory, refer to: https://access.redhat.com/articles/11258 If the postgresql service is running, it will be automatically restarted after installing this update. Workaround: If your use case requires SECURITY DEFINER functions, please follow the advice below to write them safely so they do not rely on search_path and restrict the set of users which can access them. https://www.postgresql.org/docs/devel/sql-createfunction.html#SQL-CREATEFUNCTION-SECURITY Workaround: While promptly updating PostgreSQL is the best remediation for most users, a user unable to do that can work around the vulnerability by disabling autovacuum and not manually running ANALYZE, CLUSTER, REINDEX, CREATE INDEX, VACUUM FULL, REFRESH MATERIALIZED VIEW, or a restore from output of the pg_dump command. Performance may degrade quickly under this workaround. Workaround: Using \gset with a prefix not found among specially treated variables, e.g. any lowercase string, precludes the attack in an unpatched psql.
