3. Description:

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

The following packages have been upgraded to a later upstream version:
rh-postgresql94-postgresql (9.4.14). (BZ#1484635, BZ#1484638, BZ#1484644)

Security Fix(es):

* It was found that authenticating to a PostgreSQL database account with an
empty password was possible despite libpq's refusal to send an empty
password. A remote attacker could potentially use this flaw to gain access
to database accounts with empty passwords. (CVE-2017-7546)

* An authorization flaw was found in the way PostgreSQL handled access to
the pg_user_mappings view on foreign servers. A remote, authenticated
attacker could potentially use this flaw to retrieve passwords from the
user mappings defined by the foreign server owners without actually having
the privileges to do so. (CVE-2017-7547)

* An authorization flaw was found in the way PostgreSQL handled large
objects. A remote, authenticated attacker with no privileges on a large
object could potentially use this flaw to overwrite the entire content of
the object, thus resulting in denial of service. (CVE-2017-7548)

Red Hat would like to thank the PostgreSQL project for reporting these
issues. Upstream acknowledges Ben de Graaff, Jelte Fennema, and Jeroen van
der Ham as the original reporters of CVE-2017-7546; Jeff Janes as the
original reporter of CVE-2017-7547; and Chapman Flack as the original
reporter of CVE-2017-7548.

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/):

1477184 - CVE-2017-7546 postgresql: Empty password accepted in some authentication methods
1477185 - CVE-2017-7547 postgresql: pg_user_mappings view discloses passwords to users lacking server privileges
1477187 - CVE-2017-7548 postgresql: lo_put() function ignores ACLs
