"From Red Hat Security Advisory 2016:0346 :

Updated postgresql packages that fix one security issue are now
available for Red Hat Enterprise Linux 7.

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

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

An integer overflow flaw, leading to a heap-based buffer overflow, was
found in the PostgreSQL handling code for regular expressions. A
remote attacker could use a specially crafted regular expression to
cause PostgreSQL to crash or possibly execute arbitrary code.
(CVE-2016-0773)

Red Hat would like to thank PostgreSQL upstream for reporting this
issue. Upstream acknowledges Tom Lane and Greg Stark as the original
reporters.

This update upgrades PostgreSQL to version 9.2.15. Refer to the
Release Notes linked to in the References section for a detailed list
of changes since the previous version.

All PostgreSQL users are advised to upgrade to these updated packages,
which correct this issue. If the postgresql service is running, it
will be automatically restarted after installing this update."
