Synopsis

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

Description

Updated postgresql packages that fix one security issue are now available for Red Hat Enterprise Linux 6.

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.

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