Solution

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

Summary

PostgreSQL is an advanced object-relational database management system (DBMS).
It was found that the optional PostgreSQL xml2 contrib module allowed local files and remote URLs to be read and written to with the privileges of the database server when parsing Extensible Stylesheet Language Transformations (XSLT). An unprivileged database user could use this flaw to read and write to local files (such as the database's configuration files) and remote URLs they would otherwise not have access to by issuing a specially-crafted SQL query. (CVE-2012-3488)
Red Hat would like to thank the PostgreSQL project for reporting this issue. Upstream acknowledges Peter Eisentraut as the original reporter.
All PostgreSQL users are advised to upgrade to these updated packages, which contain a backported patch to correct this issue. If the postgresql service is running, it will be automatically restarted after installing this update.
