"Two vulnerabilities related to XML processing were discovered in
PostgreSQL, a SQL database.

  - CVE-2012-3488
    contrib/xml2's xslt_process() can be used to read and
    write external files and URLs.

  - CVE-2012-3489
    xml_parse() fetches external files or URLs to resolve
    DTD and entity references in XML values.

This update removes the problematic functionality, potentially
breaking applications which use it in a legitimate way.

Due to the nature of these vulnerabilities, it is possible that
attackers who have only indirect access to the database can supply
crafted XML data which exploits this vulnerability."
