    Debian-specific: no
    CVE ID         : CVE-2012-3488 CVE-2012-3489
    
    Two vulnerabilities related to XML processing were discovered in
    PostgreSQL, an 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 natural of these vulnerabilities, it is possible that
    attackers who have only indirect address to the database can supply
    crafted XML data which exploits this vulnerability.
    
    For the stable distribution (squeeze), these problems have been fixed
    in version 8.4.13-0squeeze1.
    
    For the unstable distribution (sid), these problems have been fixed in
    version 9.1.5-1 of the postgresql-9.1 package.
    
    We recommend that you upgrade your postgresql-8.4 packages.
