CentOS Errata and Security Advisory CESA-2012:0678

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)

When configured to do SSL certificate verification, PostgreSQL only checked
the first 31 characters of the certificate’s Common Name field. Depending
on the configuration, this could allow an attacker to impersonate a server
or a client using a certificate from a trusted Certificate Authority issued
for a different name. (CVE-2012-0867)

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)

These updated packages upgrade PostgreSQL to version 8.4.11, which fixes
these issues as well as several data-corruption issues and lesser
non-security issues. 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 these issues. If the postgresql service is running, it will
be automatically restarted after installing this update.
