"From Red Hat Security Advisory 2008:0039 :

Updated postgresql packages that fix several security issues are now
available for Red Hat Enterprise Linux 3.

This update has been rated as having moderate security impact by the
Red Hat Security Response Team.

PostgreSQL is an advanced Object-Relational database management system
(DBMS). The postgresql packages include the client programs and
libraries needed to access a PostgreSQL DBMS server.

A privilege escalation flaw was discovered in PostgreSQL. An
authenticated attacker could create an index function that would be
executed with administrator privileges during database maintenance
tasks, such as database vacuuming. (CVE-2007-6600)

A privilege escalation flaw was discovered in PostgreSQL's Database
Link library (dblink). An authenticated attacker could use dblink to
possibly escalate privileges on systems with 'trust' or 'ident'
authentication configured. Please note that dblink functionality is
not enabled by default, and can only by enabled by a database
administrator on systems with the postgresql-contrib package
installed. (CVE-2007-3278, CVE-2007-6601)

All postgresql users should upgrade to these updated packages, which
include PostgreSQL 7.3.21 and resolve these issues."
