postgresql-12 12.17-0ubuntu0.20.04.1 source package in Ubuntu

Changelog

postgresql-12 (12.17-0ubuntu0.20.04.1) focal-security; urgency=medium

  * New upstream version (LP: #2040469).

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

    + However, if you use GiST indexes, it may be advisable to reindex them.

    + Also, if you are upgrading from a version earlier than 12.16, see
      those release notes as well please.

    + Fix handling of unknown-type arguments in DISTINCT "any" aggregate
      functions (Tom Lane)

      This error led to a text-type value being interpreted as an unknown-type
      value (that is, a zero-terminated string) at runtime. This could result
      in disclosure of server memory following the text value.
      (CVE-2023-5868)

    + Detect integer overflow while computing new array dimensions
      (Tom Lane)

      When assigning new elements to array subscripts that are outside the
      current array bounds, an undetected integer overflow could occur in edge
      cases. Memory stomps that are potentially exploitable for arbitrary code
      execution are possible, and so is disclosure of server memory.
      (CVE-2023-5869)

    + Prevent the <literal>pg_signal_backend</literal> role from
      signalling background workers and autovacuum processes (Noah Misch,
      Jelte Fennema-Nio)

      The documentation says that pg_signal_backend cannot issue signals to
      superuser-owned processes. It was able to signal these background
      processes, though, because they advertise a role OID of zero. Treat that
      as indicating superuser ownership. The security implications of
      cancelling one of these process types are fairly small so far as the
      core code goes (we'll just start another one), but extensions might add
      background workers that are more vulnerable.

      Also ensure that the is_superuser parameter is set correctly in such
      processes. No specific security consequences are known for that
      oversight, but it might be significant for some extensions.
      (CVE-2023-5870)

    + Fix misbehavior during recursive page split in GiST index build
      (Heikki Linnakangas)

      Fix a case where the location of a page downlink was incorrectly
      tracked, and introduce some logic to allow recovering from such
      situations rather than silently doing the wrong thing.  This error
      could result in incorrect answers from subsequent index searches.
      It may be advisable to reindex all GiST indexes after installing
      this update.

    + Details about these and many further changes can be found at:
      https://www.postgresql.org/docs/12/release-12-17.html.

  * d/p/libpgport-pkglibdir: Adjust patch to reflect upstream changes.

  * d/p/50-per-version-dirs.patch: Adjust TestLib.pm's
    scan_server_header and check_pg_config to account for
    unrelocatability of pg_config.
    These changes are needed because, during build time,
    we want to be able to run the upstream tests using the pg_config
    binary from inside the "debian/" directory, but that doesn't work out
    of the box because it will print includedir paths that also point to
    "debian/", instead of to "/usr/include".  Therefore, we need to catch
    this specific scenario and print the proper includedir paths instead.
