Problembeschreibung

Multiple vulnerabilities has been discovered and corrected in
postgresql:

Prevent access to external files/URLs via contrib/xml2's xslt_process()
(Peter Eisentraut). libxslt offers the ability to read and write both
files and URLs through stylesheet commands, thus allowing unprivileged
database users to both read and write data with the privileges of the
database server. Disable that through proper use of libxslt's security
options (CVE-2012-3488). Also, remove xslt_process()'s ability to
fetch documents and stylesheets from external files/URLs. While this
was a documented feature, it was long regarded as a bad idea. The
fix for CVE-2012-3489 broke that capability, and rather than expend
effort on trying to fix it, we're just going to summarily remove it.

Prevent access to external files/URLs via XML entity references (Noah
Misch, Tom Lane). xml_parse() would attempt to fetch external files or
URLs as needed to resolve DTD and entity references in an XML value,
thus allowing unprivileged database users to attempt to fetch data
with the privileges of the database server. While the external data
wouldn't get returned directly to the user, portions of it could
be exposed in error messages if the data didn't parse as valid XML;
and in any case the mere ability to check existence of a file might
be useful to an attacker (CVE-2012-3489).

This advisory provides the latest versions of PostgreSQL that is not
vulnerable to these issues.
