Changelog

postgresql-8.4 (8.4.12-0ubuntu11.04) natty-security; urgency=low

  * New upstream security/bug fix release: (LP: #1008317)
    - Fix incorrect password transformation in "contrib/pgcrypto"'s DES
      crypt() function.
      If a password string contained the byte value 0x80, the remainder
      of the password was ignored, causing the password to be much weaker
      than it appeared. With this fix, the rest of the string is properly
      included in the DES hash. Any stored password values that are
      affected by this bug will thus no longer match, so the stored
      values may need to be updated. (CVE-2012-2143)
    - Ignore SECURITY DEFINER and SET attributes for a procedural
      language's call handler.
      Applying such attributes to a call handler could crash the server.
      (CVE-2012-2655)
    - Allow numeric timezone offsets in timestamp input to be up to 16
      hours away from UTC.
      Some historical time zones have offsets larger than 15 hours, the
      previous limit. This could result in dumped data values being
      rejected during reload.
    - Fix timestamp conversion to cope when the given time is exactly the
      last DST transition time for the current timezone.
      This oversight has been there a long time, but was not noticed
      previously because most DST-using zones are presumed to have an
      indefinite sequence of future DST transitions.
    - Fix text to name and char to name casts to perform string
      truncation correctly in multibyte encodings.
    - Fix memory copying bug in to_tsquery().
    - Fix planner's handling of outer PlaceHolderVars within subqueries.
      This bug concerns sub-SELECTs that reference variables coming from
      the nullable side of an outer join of the surrounding query. In
      9.1, queries affected by this bug would fail with "ERROR:
      Upper-level PlaceHolderVar found where not expected". But in 9.0
      and 8.4, you'd silently get possibly-wrong answers, since the value
      transmitted into the subquery wouldn't go to null when it should.
    - Fix slow session startup when pg_attribute is very large.
      If pg_attribute exceeds one-fourth of shared_buffers, cache
      rebuilding code that is sometimes needed during session start would
      trigger the synchronized-scan logic, causing it to take many times
      longer than normal. The problem was particularly acute if many new
      sessions were starting at once.
    - Ensure sequential scans check for query cancel reasonably often.
      A scan encountering many consecutive pages that contain no live
      tuples would not respond to interrupts meanwhile.
    - Ensure the Windows implementation of PGSemaphoreLock() clears
      ImmediateInterruptOK before returning.
      This oversight meant that a query-cancel interrupt received later
      in the same query could be accepted at an unsafe time, with
      unpredictable but not good consequences.
    - Show whole-row variables safely when printing views or rules.
      Corner cases involving ambiguous names (that is, the name could be
      either a table or column name of the query) were printed in an
      ambiguous way, risking that the view or rule would be interpreted
      differently after dump and reload. Avoid the ambiguous case by
      attaching a no-op cast.
    - Fix "COPY FROM" to properly handle null marker strings that
      correspond to invalid encoding.
      A null marker string such as E'\\0' should work, and did work in
      the past, but the case got broken in 8.4.
    - Ensure autovacuum worker processes perform stack depth checking
      properly.
      Previously, infinite recursion in a function invoked by
      auto-"ANALYZE" could crash worker processes.
    - Fix logging collector to not lose log coherency under high load.
      The collector previously could fail to reassemble large messages if
      it got too busy.
    - Fix logging collector to ensure it will restart file rotation after
      receiving SIGHUP.
    - Fix WAL replay logic for GIN indexes to not fail if the index was
      subsequently dropped>
    - Fix memory leak in PL/pgSQL's "RETURN NEXT" command.
    - Fix PL/pgSQL's "GET DIAGNOSTICS" command when the target is the
      function's first variable.
    - Fix potential access off the end of memory in psql's expanded
      display ("\x") mode.
    - Fix several performance problems in pg_dump when the database
      contains many objects.
      pg_dump could get very slow if the database contained many schemas,
      or if many objects are in dependency loops, or if there are many
      owned sequences.
    - Fix "contrib/dblink"'s dblink_exec() to not leak temporary database
      connections upon error.
    - Fix "contrib/dblink" to report the correct connection name in error
      messages.
