Synopsis :

The remote Oracle Linux host is missing one or more security updates.

Description :

From Red Hat Security Advisory 2017:1983 :

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 (9.2.21). (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
