Synopsis
========

The PostgreSQL server can be tricked by a local attacker to execute
arbitrary code.

Background
==========

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

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

    -------------------------------------------------------------------
     Package            /  Vulnerable  /                    Unaffected
    -------------------------------------------------------------------
  1  dev-db/postgresql       < 7.4.7                          >= 7.4.7

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

PostgreSQL's LOAD extension is vulnerable to a local privilege
escalation discovered by John Heasman. A local user can load any shared
library, but the initialization function will then be executed with the
permissions of the PostgreSQL server.

Impact
======

A malicious local user could exploit this to execute arbitrary code
with the privileges of the PostgreSQL server.

Workaround
==========

There is no know 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"
