3. Description:

PostgreSQL is an advanced object-relational database management system
(DBMS).

The following packages have been upgraded to a later upstream version:
postgresql (9.2.21). (BZ#1449706)

Security Fix(es):

* It was found that some selectivity estimation functions did not check
user privileges before providing information from pg_statistic, possibly
leaking information. A non-administrative database user could use this flaw
to steal some information from tables they are otherwise not allowed to
access. (CVE-2017-7484)

* It was found that the pg_user_mappings view could disclose information
about user mappings to a foreign database to non-administrative database
users. A database user with USAGE privilege for this mapping could, when
querying the view, obtain user mapping data, such as the username and
password used to connect to the foreign database. (CVE-2017-7486)

Red Hat would like to thank the PostgreSQL project for reporting these
issues. Upstream acknowledges Robert Haas as the original reporter of
CVE-2017-7484; and Andrew Wheelwright as the original reporter of
CVE-2017-7486.

Additional Changes:

For detailed information on changes in this release, see the Red Hat
Enterprise Linux 7.4 Release Notes linked from the References section.

4. Solution:

For details on how to apply this update, which includes the changes
described in this advisory, refer to:

https://access.redhat.com/articles/11258

If the postgresql service is running, it will be automatically restarted
after installing this update.

5. Bugs fixed (https://bugzilla.redhat.com/):

1305979 - feature request: include libpgport.a in postgresql-devel (or its dynamic version somewhere)
1448078 - CVE-2017-7484 postgresql: Selectivity estimators bypass SELECT privilege checks
1448089 - CVE-2017-7486 postgresql: pg_user_mappings view discloses foreign server passwords
