RHEL 7 : postgresql (RHSA-2016:0346)

high Nessus Plugin ID 89096

Synopsis

The remote Red Hat host is missing a security update for postgresql.

Description

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2016:0346 advisory.

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.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL postgresql package based on the guidance in RHSA-2016:0346.
