  * New upstream security release.

    + Make the server and libpq reject extraneous data after an SSL or GSS
      encryption handshake (Tom Lane)

      A man-in-the-middle with the ability to inject data into the TCP
      connection could stuff some cleartext data into the start of a
      supposedly encryption-protected database session.

      This could be abused to send faked SQL commands to the server, although
      that would only work if the server did not demand any authentication
      data.  (However, a server relying on SSL certificate authentication
      might well not do so.) (CVE-2021-23214)

      This could probably be abused to inject faked responses to the client's
      first few queries, although other details of libpq's behavior make that
      harder than it sounds.  A different line of attack is to exfiltrate the
      client's password, or other sensitive data that might be sent early in
      the session.  That has been shown to be possible with a server
      vulnerable to CVE-2021-23214. (CVE-2021-23222)

      The PostgreSQL Project thanks Jacob Champion for reporting these
      problems.

  * New upstream version.

    + Fix mis-planning of repeated application of a projection step (Tom Lane)

      The planner could create an incorrect plan in cases where two
      ProjectionPaths were stacked on top of each other.  The only known way
      to trigger that situation involves parallel sort operations, but there
      may be other instances.  The result would be crashes or incorrect query
      results. Disclosure of server memory contents is also possible.

    + Disallow SSL renegotiation more completely (Michael Paquier)

      SSL renegotiation has been disabled for some time, but the server would
      still cooperate with a client-initiated renegotiation request. A
      maliciously crafted renegotiation request could result in a server crash
      (see OpenSSL issue CVE-2021-3449).  Disable the feature altogether on
      OpenSSL versions that permit doing so, which are 1.1.0h and newer.

  * New upstream version.

    + Prevent integer overflows in array subscripting calculations (Tom Lane)

      The array code previously did not complain about cases where an array's
      lower bound plus length overflows an integer.  This resulted in later
      entries in the array becoming inaccessible (since their subscripts could
      not be written as integers), but more importantly it confused subsequent
      assignment operations.  This could lead to memory overwrites, with
      ensuing crashes or unwanted data modifications. (CVE-2021-32027)

    + Fix mishandling of junk columns in INSERT ... ON CONFLICT ... UPDATE
      target lists (Tom Lane)

      If the UPDATE list contains any multi-column sub-selects (which give
      rise to junk columns in addition to the results proper), the UPDATE path
      would end up storing tuples that include the values of the extra junk
      columns. That's fairly harmless in the short run, but if new columns are
      added to the table then the values would become accessible, possibly
      leading to malfunctions if they don't match the datatypes of the added
      columns.

      In addition, in versions supporting cross-partition updates, a
      cross-partition update triggered by such a case had the reverse problem:
      the junk columns were removed from the target list, typically causing an
      immediate crash due to malfunction of the multi-column sub-select
      mechanism. (CVE-2021-32028)

    + Fix possibly-incorrect computation of UPDATE ... RETURNING outputs for
      joined cross-partition updates (Amit Langote, Etsuro Fujita)

      If an UPDATE for a partitioned table caused a row to be moved to another
      partition with a physically different row type (for example, one with a
      different set of dropped columns), computation of RETURNING results for
      that row could produce errors or wrong answers.  No error is observed
      unless the UPDATE involves other tables being joined to the target
      table. (CVE-2021-32029)

  * New upstream version.

    + Fix failure to check per-column SELECT privileges in some join queries
      (Tom Lane)

      In some cases involving joins, the parser failed to record all the
      columns read by a query in the column-usage bitmaps that are used for
      permissions checking.  Although the executor would still insist on some
      sort of SELECT privilege to run the query, this meant that a user having
      SELECT privilege on only one column of a table could nonetheless read
      all its columns through a suitably crafted query.

      A stored view that is subject to this problem will have incomplete
      column-usage bitmaps, and thus permissions will still not be enforced
      properly on the view after updating.  In installations that depend on
      column-level permissions for security, it is recommended to CREATE OR
      REPLACE all user-defined views to cause them to be re-parsed.

      The PostgreSQL Project thanks Sven Klemm for reporting this problem.
      (CVE-2021-20229)

    + Fix information leakage in constraint-violation error messages
      (Heikki Linnakangas)

      If an UPDATE command attempts to move a row to a different partition but
      finds that it violates some constraint on the new partition, and the
      columns in that partition are in different physical positions than in
      the parent table, the error message could reveal the contents of columns
      that the user does not have SELECT privilege on. (CVE-2021-3393)

    + Fix incorrect detection of concurrent page splits while inserting into a
      GiST index (Heikki Linnakangas)

      Concurrent insertions could lead to a corrupt index with entries placed
      in the wrong pages.  It's recommended to reindex any GiST index that's
      been subject to concurrent insertions.

    + Fix CREATE INDEX CONCURRENTLY to wait for concurrent prepared
      transactions (Andrey Borodin)

      At the point where CREATE INDEX CONCURRENTLY waits for all concurrent
      transactions to complete so that it can see rows they inserted, it must
      also wait for all prepared transactions to complete, for the same
      reason.  Its failure to do so meant that rows inserted by prepared
      transactions might be omitted from the new index, causing queries
      relying on the index to miss such rows. In installations that have
      enabled prepared transactions (max_prepared_transactions > 0), it's
      recommended to reindex any concurrently-built indexes in case this
      problem occurred when they were built.

    + Block DECLARE CURSOR ... WITH HOLD and firing of deferred triggers
      within index expressions and materialized view queries (Noah Misch)

      This is essentially a leak in the security restricted operation sandbox
      mechanism.  An attacker having permission to create non-temporary SQL
      objects could parlay this leak to execute arbitrary SQL code as a
      superuser.

      The PostgreSQL Project thanks Etienne Stalmans for reporting this
      problem. (CVE-2020-25695)

    + Fix usage of complex connection-string parameters in pg_dump,
      pg_restore, clusterdb, reindexdb, and vacuumdb (Tom Lane)

      The -d parameter of pg_dump and pg_restore, or the --maintenance-db
      parameter of the other programs mentioned, can be a connection string
      containing multiple connection parameters rather than just a database
      name.  In cases where these programs need to initiate additional
      connections, such as parallel processing or processing of multiple
      databases, the connection string was forgotten and just the basic
      connection parameters (database name, host, port, and username) were
      used for the additional connections.  This could lead to connection
      failures if the connection string included any other essential
      information, such as non-default SSL or GSS parameters. Worse, the
      connection might succeed but not be encrypted as intended, or be
      vulnerable to man-in-the-middle attacks that the intended connection
      parameters would have prevented. (CVE-2020-25694)

    + When psql's \connect command re-uses connection parameters, ensure that
      all non-overridden parameters from a previous connection string are
      re-used (Tom Lane)

      This avoids cases where reconnection might fail due to omission of
      relevant parameters, such as non-default SSL or GSS options. Worse, the
      reconnection might succeed but not be encrypted as intended, or be
      vulnerable to man-in-the-middle attacks that the intended connection
      parameters would have prevented. This is largely the same problem as
      just cited for pg_dump et al, although psql's behavior is more complex
      since the user may intentionally override some connection parameters.
      (CVE-2020-25694)

    + Prevent psql's \gset command from modifying specially-treated variables
      (Noah Misch)

      \gset without a prefix would overwrite whatever variables the server
      told it to.  Thus, a compromised server could set specially-treated
      variables such as PROMPT1, giving the ability to execute arbitrary shell
      code in the user's session.

      The PostgreSQL Project thanks Nick Cleaton for reporting this problem.
