postgresql-8.4 8.4.11-1 source package in Ubuntu


postgresql-8.4 (8.4.11-1) unstable; urgency=medium

  * Urgency medium due to security fixes.
  * New upstream bug fix/security release:
    - Require execute permission on the trigger function for "CREATE
      This missing check could allow another user to execute a trigger
      function with forged input data, by installing it on a table he
      owns. This is only of significance for trigger functions marked
      SECURITY DEFINER, since otherwise trigger functions run as the
      table owner anyway. (CVE-2012-0866)
    - Remove arbitrary limitation on length of common name in SSL
      Both libpq and the server truncated the common name extracted from
      an SSL certificate at 32 bytes. Normally this would cause nothing
      worse than an unexpected verification failure, but there are some
      rather-implausible scenarios in which it might allow one
      certificate holder to impersonate another. The victim would have to
      have a common name exactly 32 bytes long, and the attacker would
      have to persuade a trusted CA to issue a certificate in which the
      common name has that string as a prefix. Impersonating a server
      would also require some additional exploit to redirect client
      connections. (CVE-2012-0867)
    - Convert newlines to spaces in names written in pg_dump comments.
      pg_dump was incautious about sanitizing object names that are
      emitted within SQL comments in its output script. A name containing
      a newline would at least render the script syntactically incorrect.
      Maliciously crafted object names could present a SQL injection risk
      when the script is reloaded. (CVE-2012-0868)
    - Fix btree index corruption from insertions concurrent with
      An index page split caused by an insertion could sometimes cause a
      concurrently-running "VACUUM" to miss removing index entries that
      it should remove. After the corresponding table rows are removed,
      the dangling index entries would cause errors (such as "could not
      read block N in file ...") or worse, silently wrong query results
      after unrelated rows are re-inserted at the now-free table
      locations. This bug has been present since release 8.2, but occurs
      so infrequently that it was not diagnosed until now. If you have
      reason to suspect that it has happened in your database, reindexing
      the affected index will fix things.
    - Update per-column permissions, not only per-table permissions, when
      changing table owner.
      Failure to do this meant that any previously granted column
      permissions were still shown as having been granted by the old
      owner. This meant that neither the new owner nor a superuser could
      revoke the now-untraceable-to-table-owner permissions.
    - Allow non-existent values for some settings in "ALTER USER/DATABASE
      Allow default_text_search_config, default_tablespace, and
      temp_tablespaces to be set to names that are not known. This is
      because they might be known in another database where the setting
      is intended to be used, or for the tablespace cases because the
      tablespace might not be created yet. The same issue was previously
      recognized for search_path, and these settings now act like that
    - Avoid crashing when we have problems deleting table files
      Dropping a table should lead to deleting the underlying disk files
      only after the transaction commits. In event of failure then (for
      instance, because of wrong file permissions) the code is supposed
      to just emit a warning message and go on, since it's too late to
      abort the transaction. This logic got broken as of release 8.4,
      causing such situations to result in a PANIC and an unrestartable
    - Track the OID counter correctly during WAL replay, even when it
      wraps around.
      Previously the OID counter would remain stuck at a high value until
      the system exited replay mode. The practical consequences of that
      are usually nil, but there are scenarios wherein a standby server
      that's been promoted to master might take a long time to advance
      the OID counter to a reasonable value once values are needed.
    - Fix regular expression back-references with - attached.
      Rather than enforcing an exact string match, the code would
      effectively accept any string that satisfies the pattern
      sub-expression referenced by the back-reference symbol.
      A similar problem still afflicts back-references that are embedded
      in a larger quantified expression, rather than being the immediate
      subject of the quantifier. This will be addressed in a future
      PostgreSQL release.
    - Fix recently-introduced memory leak in processing of inet/cidr
    - Fix dangling pointer after "CREATE TABLE AS"/"SELECT INTO" in a
      SQL-language function.
      In most cases this only led to an assertion failure in
      assert-enabled builds, but worse consequences seem possible.
    - Fix I/O-conversion-related memory leaks in plpgsql.
    - Improve pg_dump's handling of inherited table columns.
      pg_dump mishandled situations where a child column has a different
      default expression than its parent column. If the default is
      textually identical to the parent's default, but not actually the
      same (for instance, because of schema search path differences) it
      would not be recognized as different, so that after dump and
      restore the child would be allowed to inherit the parent's default.
      Child columns that are NOT NULL where their parent is not could
      also be restored subtly incorrectly.
    - Fix pg_restore's direct-to-database mode for INSERT-style table
      Direct-to-database restores from archive files made with
      "--inserts" or "--column-inserts" options fail when using
      pg_restore from a release dated September or December 2011, as a
      result of an oversight in a fix for another problem. The archive
      file itself is not at fault, and text-mode output is okay.
    - Allow AT option in ecpg DEALLOCATE statements.
      The infrastructure to support this has been there for awhile, but
      through an oversight there was still an error check rejecting the
    - Fix error in "contrib/intarray"'s int[] & int[] operator.
      If the smallest integer the two input arrays have in common is 1,
      and there are smaller values in either array, then 1 would be
      incorrectly omitted from the result.
    - Fix error detection in "contrib/pgcrypto"'s encrypt_iv() and
      These functions failed to report certain types of invalid-input
      errors, and would instead return random garbage values for
      incorrect input.
    - Fix one-byte buffer overrun in "contrib/test_parser".
      The code would try to read one more byte than it should, which
      would crash in corner cases. Since "contrib/test_parser" is only
      example code, this is not a security issue in itself, but bad
      example code is still bad.
    - Use __sync_lock_test_and_set() for spinlocks on ARM, if available.
      This function replaces our previous use of the SWPB instruction,
      which is deprecated and not available on ARMv6 and later. Reports
      suggest that the old code doesn't fail in an obvious way on recent
      ARM boards, but simply doesn't interlock concurrent accesses,
      leading to bizarre failures in multiprocess operation.
    - Use "-fexcess-precision=standard" option when building with gcc
      versions that accept it.
      This prevents assorted scenarios wherein recent versions of gcc
      will produce creative results.
    - Allow use of threaded Python on FreeBSD.
      Our configure script previously believed that this combination
      wouldn't work; but FreeBSD fixed the problem, so remove that error
  * Drop 04-armel-tas.patch, applied upstream.

postgresql-8.4: object-relational SQL database, version 8.4 server

 PostgreSQL is a fully featured object-relational database management
 system. It supports a large part of the SQL standard and is designed
 to be extensible by users in many aspects. Some of the features are:
 ACID transactions, foreign keys, views, sequences, subqueries,
 triggers, user-defined types and functions, outer joins, multiversion
 concurrency control. Graphical user interfaces and bindings for many
 programming languages are available as well.
 This package provides the database server for PostgreSQL 8.4. Servers
 for other major release versions can be installed simultaneously and
 are coordinated by the postgresql-common package. A package providing
 ident-server is needed if you want to authenticate remote connections
 with identd.

postgresql-client-8.4: front-end programs for PostgreSQL 8.4

 This package contains client and administrative programs for
 PostgreSQL: these are the interactive terminal client psql and
 programs for creating and removing users and databases.
 This is the client package for PostgreSQL 8.4. If you install
 PostgreSQL 8.4 on a standalone machine, you need the server package
 postgresql-8.4, too. On a network, you can install this package on
 many client machines, while the server package may be installed on
 only one machine.

postgresql-contrib-8.4: additional facilities for PostgreSQL

 The PostgreSQL contrib package provides several additional features
 for the PostgreSQL database. This version is built to work with the
 server package postgresql-8.4. contrib often serves as a testbed for
 features before they are adopted into PostgreSQL proper:
  adminpack - File and log manipulation routines, used by pgAdmin
  btree_gist - B-Tree indexing using GiST (Generalised Search Tree)
  chkpass - An auto-encrypted password datatype
  cube - Multidimensional-cube datatype (GiST indexing example)
  dblink - Functions to return results from a remote database
  earthdistance - Operator for computing the distance (in miles) between
                   two points on the earth's surface
  fuzzystrmatch - Levenshtein, metaphone, and soundex fuzzy string matching
  hstore - Store (key, value) pairs
  intagg - Integer aggregator/enumerator
  _int - Index support for arrays of int4, using GiST (benchmark
                   needs the libdbd-pg-perl package)
  isn - type extensions for ISBN, ISSN, ISMN, EAN13 product numbers
  lo - Large Object maintenance
  ltree - Tree-like data structures
  oid2name - Maps OIDs to table names
  pageinspect - Inspection of database pages
  pg_buffercache - Real time queries on the shared buffer cache
  pg_freespacemap- Displays the contents of the free space map (FSM)
  pg_trgm - Determine the similarity of text based on trigram matching
  pg_standby - Create a warm stand-by server
  pgbench - TPC-B like benchmark
  pgcrypto - Cryptographic functions
  pgrowlocks - A function to return row locking information
  pgstattuple - Returns the percentage of dead tuples in a table; this
                   indicates whether a vacuum is required.
  seg - Confidence-interval datatype (GiST indexing example)
  spi - PostgreSQL Server Programming Interface; 4 examples of
                   its use:
                   autoinc - A function for implementing AUTOINCREMENT/
                   insert_username - function for inserting user names
                   moddatetime - Update modification timestamps
                   refint - Functions for implementing referential
                                integrity (foreign keys). Note that this is
                                now superseded by built-in referential
                   timetravel - Re-implements in user code the time travel
                                feature that was removed in 6.3.
  tablefunc - examples of functions returning tables
  uuid-ossp - UUID generation functions
  vacuumlo - Remove orphaned large objects
