postgresql security update

CentOS Errata and Security Advisory CESA-2012:0677

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

The pg_dump utility inserted object names literally into comments in the
SQL script it produces. An unprivileged database user could create an
object whose name includes a newline followed by an SQL command. This SQL
command might then be executed by a privileged user during later restore of
the backup dump, allowing privilege escalation. (CVE-2012-0868)

CREATE TRIGGER did not do a permissions check on the trigger function to
be called. This could possibly allow an authenticated database user to
call a privileged trigger function on data of their choosing.
(CVE-2012-0866)

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