Changelog

postgresql-12 (12.7-0ubuntu0.20.04.1) focal-security; urgency=medium

  * New upstream version (LP: #1928773).

    + 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)

 Header files and static library for compiling C programs to link
 with the libpq library in order to communicate with a PostgreSQL
 database backend.
 .
 PostgreSQL is an object-relational SQL database management system.

libpq5: PostgreSQL C client library

 libpq is a C library that enables user programs to communicate with
 the PostgreSQL database server. The server can be on another machine
 and accessed through TCP/IP. This version of libpq is compatible
 with servers from PostgreSQL 8.2 or later.
 .
 This package contains the run-time library, needed by packages using
 libpq.
 .

postgresql-12: object-relational SQL database, version 12 server

 PostgreSQL is a powerful, open source object-relational database
 system. It is fully ACID compliant, has full support for foreign
 keys, joins, views, triggers, and stored procedures (in multiple
 languages). It includes most SQL:2008 data types, including INTEGER,
 NUMERIC, BOOLEAN, CHAR, VARCHAR, DATE, INTERVAL, and TIMESTAMP. It
 also supports storage of binary large objects, including pictures,
 sounds, or video. It has native programming interfaces for C/C++,
 Java, .Net, Perl, Python, Ruby, Tcl, ODBC, among others, and
 exceptional documentation.
