postgresql-9.5 9.5.24-0ubuntu0.16.04.1 source package in Ubuntu

Changelog

postgresql-9.5 (9.5.24-0ubuntu0.16.04.1) xenial-security; urgency=medium

  * New upstream version.
    + 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.
      (CVE-2020-25696)

 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

  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

  seg - Confidence-interval datatype (GiST indexing example)
  sepgsql - mandatory access control (MAC) based on SELinux
  spi - PostgreSQL Server Programming Interface; 4 examples of
                   its use:

                   moddatetime - Update modification timestamps
                   refint - Functions for implementing referential
                                integrity (foreign keys). Note that this is

                   timetravel - Re-implements in user code the time travel
                                feature that was removed in 6.3.
