Synopsis
========
PostgreSQL contains a vulnerability that could result in SQL privilege
escalation.

Background
==========
PostgreSQL is an open source object-relational database management
system.

Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 dev-db/postgresql < 8.0.13 >= 8.0.13
*>= 7.4.17
*>= 7.3.19

Description
===========
An error involving insecure search_path settings in the SECURITY
DEFINER functions has been reported in PostgreSQL.

Impact
======
If allowed to call a SECURITY DEFINER function, an attacker could gain
the SQL privileges of the owner of the called function.

Workaround
==========
There is no known workaround at this time.

Resolution
==========
All PostgreSQL users should upgrade to the latest version and fix their
SECURITY DEFINER functions:

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

In order to fix the SECURITY DEFINER functions, PostgreSQL users are
advised to refer to the PostgreSQL documentation:
http://www.postgresql.org/docs/techdocs.77
