DESCRIPTION:
A security issue has been reported in PostgreSQL, which can be
exploited by malicious users to perform certain actions with
escalated privileges.

The security issue is caused due to an error in the application when
executing a function in the same session as another user. This can be
exploited to execute arbitrary SQL code with the privileges of that
user.

Successful exploitation requires that the functions and procedures of
the external procedural languages use SECURITY DEFINER functions, SET
ROLE, or SET SESSION AUTHORIZATION.

SOLUTION:
Update to version 9.0.1, 8.4.5, 8.3.12, 8.2.18, 8.1.22, 8.0.26, or
7.4.30, which fix the security issue in PL/perl and PL/tcl (a fix for
PL/PHP is reportedly in development).

PROVIDED AND/OR DISCOVERED BY:
The vendor credits Tim Bunce.
