Synopsis
========

PostgreSQL is vulnerable to several buffer overflows in the PL/PgSQL
parser leading to execution of arbitrary code.

Background
==========

PostgreSQL is a SQL compliant, open source object-relational database
management system.

Affected packages
=================

    -------------------------------------------------------------------
     Package            /  Vulnerable  /                    Unaffected
    -------------------------------------------------------------------
  1  dev-db/postgresql     < 8.0.1-r1                      >= 8.0.1-r1
                                                          *>= 7.4.7-r1
                                                          *>= 7.3.9-r1

Description
===========

PostgreSQL is vulnerable to several buffer overflows in the PL/PgSQL
parser.

Impact
======

A remote attacker could send a malicious query resulting in the
execution of arbitrary code with the permissions of the user running
PostgreSQL.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All PostgreSQL users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=dev-db/postgresql-7.4.7-r1"
