postgresql-14 (14.8-0ubuntu0.22.10.1) kinetic-security; urgency=medium

  * New upstream version (LP: #2019214).

    + A dump/restore is not required for those running 14.X.

    + Also, if you are upgrading from a version earlier than 14.4, see
      those release notes as well please.

    + Prevent CREATE SCHEMA from defeating changes in search_path
      (Alexander Lakhin)

      Within a CREATE SCHEMA command, objects in the prevailing
      search_path, as well as those in the newly-created schema, would be
      visible even within a called function or script that attempted to set
      a secure search_path. This could allow any user having permission to
      create a schema to hijack the privileges of a security definer
      function or extension script.
      (CVE-2023-2454)

    + Enforce row-level security policies correctly after inlining a
      set-returning function (Stephen Frost, Tom Lane)

      If a set-returning SQL-language function refers to a table having
      row-level security policies, and it can be inlined into a calling
      query, those RLS policies would not get enforced properly in some
      cases involving re-using a cached plan under a different role. This
      could allow a user to see or modify rows that should have been
      invisible.
      (CVE-2023-2455)
