some reading on the subject. 1) PostgreSQL uses ephemeral keying, for its connections (good thing) 2) PostgreSQL doesn't set the cipher list that it allows (bad thing, fixed) 3) PostgreSQL's renegotiation code wasn't text book correct (could be bad, fixed) 4) The rate of renegotiating was insanely low (as Tom pointed out, set to a more reasonable level) I haven't checked around much to see if there are any other SSL bits that need some review, but I'm doing some OpenSSL work right now and'll send patches for improvements along the way (if I find them). At the very least, the changes in this patch will make security folks happier for sure. The constant renegotiation of sessions was likely a boon to systems that had bad entropy gathering means (read: Slowaris /dev/rand|/dev/urand != ANDIrand). The new limit for renegotiations is 512MB which should be much more reasonable. Sean Chittenden |

PostgreSQL Database Management System ===================================== This directory contains the source code distribution of the PostgreSQL database management system. PostgreSQL is an advanced object-relational database management system that supports an extended subset of the SQL standard, including transactions, foreign keys, subqueries, triggers, user-defined types and functions. This distribution also contains several language bindings, including C, Perl, Python, and Tcl, as well as a JDBC driver. The ODBC and C++ interfaces have been moved to the PostgreSQL Projects Web Site at http://gborg.postgresql.org for separate maintenance. See the file INSTALL for instructions on how to build and install PostgreSQL. That file also lists supported operating systems and hardware platforms and contains information regarding any other software packages that are required to build or run the PostgreSQL system. Changes between all PostgreSQL releases are recorded in the file HISTORY. Copyright and license information can be found in the file COPYRIGHT. A comprehensive documentation set is included in this distribution; it can be read as described in the installation instructions. The latest version of this software may be obtained at ftp://ftp.postgresql.org/pub/. For more information look at our web site located at http://www.postgresql.org/.
