Debian DSA-2534-1 : postgresql-8.4 - several vulnerabilities

medium Nessus Plugin ID 61662

Synopsis

The remote Debian host is missing a security-related update.

Description

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.

Solution

Upgrade the postgresql-8.4 packages.

For the stable distribution (squeeze), these problems have been fixed in version 8.4.13-0squeeze1.
