RHEL 6 / 7 : postgresql (RHSA-2015:0750)

critical Nessus Plugin ID 82466

Synopsis

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

Description

Updated postgresql packages that fix multiple security issues are now available for Red Hat Enterprise Linux 6 and 7.

Red Hat Product Security has rated this update as having Moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

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

An information leak flaw was found in the way the PostgreSQL database server handled certain error messages. An authenticated database user could possibly obtain the results of a query they did not have privileges to execute by observing the constraint violation error messages produced when the query was executed. (CVE-2014-8161)

A buffer overflow flaw was found in the way PostgreSQL handled certain numeric formatting. An authenticated database user could use a specially crafted timestamp formatting template to cause PostgreSQL to crash or, under certain conditions, execute arbitrary code with the permissions of the user running PostgreSQL. (CVE-2015-0241)

A stack-buffer overflow flaw was found in PostgreSQL's pgcrypto module. An authenticated database user could use this flaw to cause PostgreSQL to crash or, potentially, execute arbitrary code with the permissions of the user running PostgreSQL. (CVE-2015-0243)

A flaw was found in the way PostgreSQL handled certain errors that were generated during protocol synchronization. An authenticated database user could use this flaw to inject queries into an existing connection. (CVE-2015-0244)

Red Hat would like to thank the PostgreSQL project for reporting these issues. Upstream acknowledges Stephen Frost as the original reporter of CVE-2014-8161; Andres Freund, Peter Geoghegan, Bernd Helmle, and Noah Misch as the original reporters of CVE-2015-0241; Marko Tiikkaja as the original reporter of CVE-2015-0243; and Emil Lenngren as the original reporter of CVE-2015-0244.

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

Solution

Update the affected packages.
