Security Updates for Firebird 2.5.2 and Firebird 2.1.5 are released

Leave a comment

The Firebird Project releases important security updates addressing a remote stack buffer overflow discovered in the Firebird Server during March, 2013.

This vulnerability allows an unauthenticated user to crash the server and opens a gate for remote code execution, so it’s highly recommended to upgrade your server installations. Security updates are available for Firebird 2.5.2 and Firebird 2.1.5 versions. They don’t include any changes other than the bugfix for the aforementioned buffer overrun.

German court case confirms validity of the LGPL on Firebird related project FreeadhocUDF

Leave a comment

Buhl Data Service GmbH, the developer of the WISO Mein BüroGerman language link2009 software has agreed to pay €15,000 (approximately £13,000) to adhoc dataservice GmbH for using its LGPL-licensed FreeadhocUDF open source library in his business software without observing the LGPL’s licensing terms. The GNU Lesser Public Licence allows software to be used free of charge, but it stipulates that developers must give prominent notice to where the licensed code was used, point out that the code is under the LGPL, include a copy of the LGPL, and make the library’s source code available.

The payment was negotiated as a settlement between the involved parties and concludes a court case. Back in January 2011, the regional court in Bochum, Germany, had ruledGerman language linkthat the use of the FreeadhocUDF library in WISO Mein Büro 2009 was not legitimate because it violated the LGPL’s licensing terms. The court ruled that adhoc dataservice GmbH was, therefore, entitled to know in which products the library was used, what product quantities were released, and how much revenue was generated.

New implementation for wire protocol in Jaybird and all drivers need a faster wire protocol

4 comments

Mark Rotteveel wrote on twitter about the Jaybird improvement:

Writing a new implementation of the wire protocol in Jaybird. I fear it is going to cascade into a total rewrite of the driver

Jiri chatted later:

IMO the whole “communication layer” needs redesign. It’s (way) too legacy.

And later on the twitter channel Brent Rowland wrote:

Contemplating creating a new wire protocol. Stop me now…
I have a replication system for Firebird I need to extend across a WAN. Firebird has no built-in replication and the protocol is chatty.

Editor:All these conversations are around Firebird 2.5.x protocol , there is work conducted by Dmitry Yemanov on improving the Firebird 3.x protocol

SplendidCRM on FirebirdSQL demo page and Database structure

Leave a comment

SplendidCRM (version C# of SugarCRM) is ported from MSSQL over to
FirebirdSQL 2.5.2

It is in a “testable” debug version on this url http://zeos.tetrasys.eu

username : user
password : user

This changes from the usual will/will 🙂

It is the “community” version and I would like to have your feedback on their added value in a CRM, before carrying over the enterprise modules.

Two precision/information points:
1) One is on a small DSL in Finland, so your GSM has more disponibility and bandwidth
2) the data structure is available for viewing here http://blog.tetrasys.eu/zeos-firebirdsql-structure.aspx

Your comments are welcome 🙂

I will add one more comment from the Firebird porter :

Thanks to Firebird, the memory and processing space has been reduced with two thirds when migrated from MSSQL to FirebirdSQL.
Why don’t everybody switch over to Firebird? 🙂

 

New IBExpertBenchmark tool: Compare your db server performance on different hardware, OS’s and Firebird server version

Leave a comment

Have you ever tried to compare the database speed of your Firebird server with new server hardware? Is a XEON Machine better than an Opteron? What improvements can you expect from fast SAS hard disks, RAID controllers or Enterprise SSDs? Is SuperClassic really better than Superserver?
We’ve created a new tool which offers a reproducible speed index for your computer working as a Firebird Server: IBExpertBenchmark
