3. Description:
PostgreSQL is an advanced object-relational database management system
(DBMS).
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)
Red Hat would like to thank the PostgreSQL project for reporting this
issue. Upstream acknowledges Ben de Graaff, Jelte Fennema, and Jeroen van
der Ham as the original reporters.

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.
