Red Hat: RHSA-2012-0677-01 Moderate: PostgreSQL Security Fix

red hat
Calendar Grey May 21, 2012
Dist Redhat Esm H88
Oracle has issued a patch for MySQL tackling two significant vulnerabilities. Safeguard your databases accordingly.
Updated postgresql packages that fix two security issues are now available for Red Hat Enterprise Linux 5

Solution

Before applying this update, make sure all previously-released errata relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/articles/11258

Summary

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.
