[ubuntu/focal-security] postgresql-12 12.11-0ubuntu0.20.04.1 (Accepted)

[Marc Deslauriers]

postgresql-12 (12.11-0ubuntu0.20.04.1) focal-security; urgency=medium

  * New upstream version (LP: #1973627)

    + A dump/restore is not required for those running 12.X.

    + However, if you are upgrading from a version earlier than 12.10,
      see those release notes as well.

    + Confine additional operations within "security restricted operation"
      sandboxes (Sergey Shinderuk, Noah Misch).

      Autovacuum, CLUSTER, CREATE INDEX, REINDEX, REFRESH MATERIALIZED VIEW,
      and pg_amcheck activated the "security restricted operation" protection
      mechanism too late, or even not at all in some code paths. A user having
      permission to create non-temporary objects within a database could
      define an object that would execute arbitrary SQL code with superuser
      permissions the next time that autovacuum processed the object, or that
      some superuser ran one of the affected commands against it.

      The PostgreSQL Project thanks Alexander Lakhin for reporting this
      problem.
      (CVE-2022-1552)

postgresql-12 (12.10-0ubuntu0.20.04.1) focal; urgency=medium

  * New upstream version (LP: #1961127).

    + A dump/restore is not required for those running 12.X.

    + However, if you have applied REINDEX CONCURRENTLY to a TOAST table's
      index, or observe failures to access TOAST datums, there has been a
      fix for this problem. Any existing corrupted indexes can be repaired
      by reindexing again.

    + Also, if you are upgrading from a version earlier than 12.9, see
      those release notes as well please.
