Synopsis :

The remote Red Hat host is missing one or more security updates.

Description :

An update for postgresql is now available for Red Hat Enterprise Linux

Red Hat Product Security has rated this update as having a security
impact of Moderate. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available for each
vulnerability from the CVE link(s) in the References section.

PostgreSQL is an advanced object-relational database management system

The following packages have been upgraded to a later upstream version:
postgresql (9.2.23). (BZ#1484639, BZ#1484647)

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)

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; and Jeff Janes
as the original reporter of CVE-2017-7547.
