Synopsis:          Moderate: postgresql84 security update
Advisory ID:       RHSA-2010:0430-01
Product:           Red Hat Enterprise Linux
Advisory URL:      https://access.redhat.com/errata/RHSA-2010:0430.html
Issue date:        2010-05-19
CVE Names:         CVE-2010-1169 CVE-2010-1170 
====================================================================
1. Summary:

Updated postgresql84 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). PL/Perl and PL/Tcl allow users to write PostgreSQL functions in the
Perl and Tcl languages, and are installed in trusted mode by default. In
trusted mode, certain operations, such as operating system level access,
are restricted.

A flaw was found in the way PostgreSQL enforced permission checks on
scripts written in PL/Perl. If the PL/Perl procedural language was
registered on a particular database, an authenticated database user running
a specially-crafted PL/Perl script could use this flaw to bypass intended
PL/Perl trusted mode restrictions, allowing them to run arbitrary Perl
scripts with the privileges of the database server. (CVE-2010-1169)

Red Hat would like to thank Tim Bunce for responsibly reporting the
CVE-2010-1169 flaw.

A flaw was found in the way PostgreSQL enforced permission checks on

scripts with the privileges of the database server. (CVE-2010-1170)

These packages upgrade PostgreSQL to version 8.4.4. Refer to the PostgreSQL
Release Notes for a list of changes:

https://https://www.postgresql.org/docs/8.4/release.html

All PostgreSQL users are advised to upgrade to these updated packages,
which 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
