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