Red Hat Security Advisory 2012-0677-01

Red Hat Security Advisory 2012-0677-01
Posted May 22, 2012
Authored by Red Hat | Site access.redhat.com

Red Hat Security Advisory 2012-0677-01 - PostgreSQL is an advanced object-relational database management system. The pg_dump utility inserted object names literally into comments in the SQL script it produces. An unprivileged database user could create an object whose name includes a newline followed by an SQL command. This SQL command might then be executed by a privileged user during later restore of the backup dump, allowing privilege escalation. CREATE TRIGGER did not do a permissions check on the trigger function to be called. This could possibly allow an authenticated database user to call a privileged trigger function on data of their choosing.

Red Hat Security Advisory

Synopsis: Moderate: postgresql security update
Advisory ID: RHSA-2012:0677-01
Product: Red Hat Enterprise Linux
Advisory URL: https://rhn.redhat.com/errata/RHSA-2012-0677.html
Issue date: 2012-05-21
CVE Names: CVE-2012-0866 CVE-2012-0868
=====================================================================

1. Summary:

Updated postgresql packages that fix two security issues are now available
for Red Hat Enterprise Linux 5.

The Red Hat Security Response Team 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:

RHEL Desktop Workstation (v. 5 client) - i386, x86_64
Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64
Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64

3. Description:

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

The pg_dump utility inserted object names literally into comments in the
SQL script it produces. An unprivileged database user could create an
object whose name includes a newline followed by an SQL command. This SQL
command might then be executed by a privileged user during later restore of
the backup dump, allowing privilege escalation. (CVE-2012-0868)

CREATE TRIGGER did not do a permissions check on the trigger function to
be called. This could possibly allow an authenticated database user to
call a privileged trigger function on data of their choosing.
(CVE-2012-0866)

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.

4. Solution:

Before applying this update, make sure all previously-released errata
relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to
use the Red Hat Network to apply this update are available at
https://access.redhat.com/knowledge/articles/11258

5. Bugs fixed (http://bugzilla.redhat.com/):

797222 - CVE-2012-0866 postgresql: Absent permission checks on trigger function to be called when creating a trigger
797917 - CVE-2012-0868 postgresql: SQL injection due unsanitized newline characters in object names
