postgresql-16 (16.4-0ubuntu0.24.04.1) noble-security; urgency=medium

  * New upstream version (LP: #2076183).

    + A dump/restore is not required for those running 16.X.

    + However, if you are upgrading from a version earlier than 16.3, see
      those release notes as well please.

    + Prevent unauthorized code execution during pg_dump (Masahiko Sawada)

      An attacker able to create and drop non-temporary objects could inject
      SQL code that would be executed by a concurrent pg_dump session with the
      privileges of the role running pg_dump (which is often a superuser).
      The attack involves replacing a sequence or similar object with a view
      or foreign table that will execute malicious code.  To prevent this,
      introduce a new server parameter restrict_nonsystem_relation_kind that
      can disable expansion of non-builtin views as well as access to foreign
      tables, and teach pg_dump to set it when available.  Note that the
      attack is prevented only if both pg_dump and the server it is dumping
      from are new enough to have this fix.

      The PostgreSQL Project thanks Noah Misch for reporting this problem.
      (CVE-2024-7348)
