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"
