Product:           Red Hat Satellite
Advisory URL:      https://rhn.redhat.com/errata/RHSA-2015-0856.html

=====================================================================

1. Summary:

Updated postgresql packages that fix multiple security issues are now
available for Red Hat Satellite 5.7.

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.

2. Relevant releases/architectures:

Red Hat Satellite 5.7 (RHEL v.6) - s390x, x86_64
Red Hat Satellite Managed DB 5.7 (RHEL v.6) - s390x, x86_64

3. Description:

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.
