Notable Security Fixes

Crunchy PostgreSQL 16.3-0, 15.7-0, and 14.12-0 include:

• CVE-2024-4317

  Restrict visibility of pg_stats_ext and pg_stats_ext_exprs entries to the table owner.

  These views failed to hide statistics for expressions that involve columns the accessing user does not have permission to read. View columns such as most_common_vals might expose security-relevant data. The potential interactions here are not fully clear, so in the interest of erring on the side of safety, make rows in these views visible only to the owner of the associated table.

  By itself, this fix will only fix the behavior in newly initdb'd database clusters. If you wish to apply this change in an existing cluster, you will need to do the following:

  1. Find the SQL script fix-CVE-2024-4317.sql in the share directory of the PostgreSQL installation. In Crunchy Data's PostgreSQL 16 RPM packages, the script can be found in folder /usr/pgsql-16/share/ after installing the postgresql16-server RPM. Be sure to use the script appropriate to your PostgreSQL major version. If you do not see this file, either your version is not vulnerable (only v14-v16 are affected) or your minor version is too old to have the fix.

  2. In each database of the cluster, run the fix-CVE-2024-4317.sql script as superuser. In psql this would look like

     \i /usr/pgsql-16/share/fix-CVE-2024-4317.sql

     (adjust the file path as appropriate). Any error probably indicates that you've used the wrong script version. It will not hurt to run the script more than once.

  3. Do not forget to include the template0 and template1 databases, or the vulnerability will still exist in databases you create later. To fix template0, you'll need to temporarily make it accept connections. Do that with:

     ALTER DATABASE template0 WITH ALLOW_CONNECTIONS true;

     and then after fixing template0, undo it with

     ALTER DATABASE template0 WITH ALLOW_CONNECTIONS false;

Features

• The monitoring stack has undergone a number of significant improvements in 5.5, including:
