postgresql-12 12.4-0ubuntu0.20.04.1 source package in Ubuntu

Changelog

postgresql-12 (12.4-0ubuntu0.20.04.1) focal-security; urgency=medium

  * New upstream release (LP: #1892335).
    - Set a secure search_path in logical replication walsenders and apply
      workers (Noah Misch)

      A malicious user of either the publisher or subscriber database could
      potentially cause execution of arbitrary SQL code by the role running
      replication, which is often a superuser.  Some of the risks here are
      equivalent to those described in CVE-2018-1058, and are mitigated in
      this patch by ensuring that the replication sender and receiver execute
      with empty search_path settings. (As with CVE-2018-1058, that change
      might cause problems for under-qualified names used in replicated
      tables' DDL.)  Other risks are inherent in replicating objects that
      belong to untrusted roles; the most we can do is document that there is
      a hazard to consider.
      CVE-2020-14349

    - Make contrib modules' installation scripts more secure (Tom Lane)

      Attacks similar to those described in CVE-2018-1058 could be carried out
      against an extension installation script, if the attacker can create
      objects in either the extension's target schema or the schema of some
      prerequisite extension.  Since extensions often require superuser
      privilege to install, this can open a path to obtaining superuser
      privilege.  To mitigate this risk, be more careful about the search_path
      used to run an installation script; disable check_function_bodies within
      the script; and fix catalog-adjustment queries used in some contrib
      modules to ensure they are secure.  Also provide documentation to help
      third-party extension authors make their installation scripts secure.
      This is not a complete solution; extensions that depend on other
      extensions can still be at risk if installed carelessly.
      CVE-2020-14350

 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.
