Synopsis
=======

PostgreSQL is vulnerable to Denial of Service attacks and possibly allows unprivileged users to gain administrator rights.

Background
=========

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

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

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 dev-db/postgresql lt; 8.0.2-r1 *gt;= 7.4.7-r2
*gt;= 8.0.1-r3
gt;= 8.0.2-r1

Description
==========

PostgreSQL gives public EXECUTE access to a number of character conversion routines, but doesn't validate the given arguments (CAN-2005-1409). It has also been reported that the contrib/tsearch2 module of PostgreSQL misdeclares the return value of some functions as "internal" (CAN-2005-1410).

Impact
=====

An attacker could call the character conversion routines with specially setup arguments to crash the backend process of PostgreSQL or to potentially gain administrator rights. A malicious user could also call the misdeclared functions of the contrib/tsearch2 module, resulting in a Denial of Service or other, yet uninvestigated, impacts.

Workaround
=========

There is no known workaround at this time.

Resolution
=========

All PostgreSQL users should update to the latest available version and follow the guide at http://www.postgresql.org/about/news.315

# emerge --sync
# emerge --ask --oneshot --verbose dev-db/postgresql
