+
+  * New upstream version.
+
+    + Restrict visibility of pg_stats_ext and pg_stats_ext_exprs entries to
+      the table owner (Nathan Bossart)
+
+      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.
+
+      The PostgreSQL Project thanks Lukas Fittl for reporting this problem.
+      (CVE-2024-4317)
+
+      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:
+
+        In each database of the cluster, run the fix-CVE-2024-4317.sql script
+        as superuser. In psql this would look like
+          \i /usr/share/postgresql/15/fix-CVE-2024-4317.sql
+        Any error probably indicates that you've used the wrong script
+        version.  It will not hurt to run the script more than once.
+
+        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;
