3. Description:

PostgreSQL is an advanced object-relational database management system
(DBMS).

A stack-based buffer overflow flaw was found in the way PostgreSQL
processed certain tokens from an SQL query when the intarray module was
enabled on a particular database. An authenticated database user running a
specially-crafted SQL query could use this flaw to cause a temporary denial
of service (postgres daemon crash) or, potentially, execute arbitrary code
with the privileges of the database server. (CVE-2010-4015)

Red Hat would like to thank Geoff Keating of the Apple Product Security
team for reporting this issue.

These updated postgresql84 packages upgrade PostgreSQL to version 8.4.7.
Refer to the PostgreSQL Release Notes for a full list of changes:

http://www.postgresql.org/docs/8.4/static/release.html

All PostgreSQL users are advised to upgrade to these updated packages,
which correct this issue. If the postgresql service is running, it will be
automatically restarted after installing this update.
