In this paper we are going to describe a kind of vulnerability that is known in the literature but also poor documented. In fact, the problem that is going to be analyzed can be reduced to a memory adjacent overwriting attack but usually it is obtained exploiting the last null byte of a buffer, hence we are going to show that the same result is still possible writing behind a buffer, under certain conditions. To fully understand the subject of this article it's necessary to describe the memory organization1 of running processes, then the memory adjacent overwrite attack, concluding with our analysis.

In 1998, I knew one person who used Linux. He and I ran Red Hat 4.2 and 5.0 on fast 486 Intel processors at Cap Gemini. One day I asked him who to call for support and he answered, "What"? So, I started a Linux call center.

GPL-licensed software poses no special threat to companies covered by the Sarbanes-Oxley Act of 2002 (SOX), according to a whitepaper released by the Software Freedom Law Center (SFLC). The paper rebuts recent statements to the contrary from Wasabi Systems, an embedded software publisher that advocates a competing open source license.

DistroWatch reports - The ParallelKnoppix live CD has been updated. What's new? Open MPI at version 1.0.1, the pi example for C shows how to use it; mpich.tar.gz is included in the 'Examples' directory, this shows how to compile and install software on a running cluster, and lets you run a very cool parallel Mandelbrot set plotter; Ganglia removed for the time being; missing MPITB source included; montecarlo.m does dynamic load balancing and is robust to node failure; tutorial updated.

OSDir captured ParallelKnoppix 2006-02-20 nicely in their recent Screenshot Tour.

Michael Dell, chairman of Dell Inc. believes in offering Linux on the desktop, server, and workstation. What he doesn't believe in, for now, is giving Linux full support on the desktop. In an exclusive interview, Dell explained his company's Linux desktop strategy to DesktopLinux.com's Steven J. Vaughan Nichols.

The Docebo project combines a learning management system (LMS), content management system (CMS), and knowledge management system (KMS) in one suite, available under the GNU General Public License (GPL). The integration of these components into a single suite saves users a lot of time, and provides a clean and convenient single window interface. I found Docebo to be very capable, though it does have a few glitches.

The one-year-old company Vyatta is attempting to grow a community around the Open Flexible Router (OFR) it has compiled with several already available pieces of software -- and perhaps bring something new to the router market.

The final minutes of the battle between BlackBerry maker Research In Motion (RIM) and NTP Incorporated hinged on five patents that, when the dust settles, may not be enforceable. You know the outcome. Over $612 million slid from RIM's checking account into NTP's. Everybody picked sides, based largely on principle... or BlackBerry ownership. But once you've read the patents for yourself, you may find yourself switching sides.

There was once a time when Sharp was a cutting-edge producer of PDAs, and the company's Zaurus was a market leader. But as the market has matured (and declined), the Zaurus line has devolved into little more than a pocket dictionary, giving it something of a second life in countries like Japan and Korea, where such products are still popular, but continuing to marginalize it as a portable computer. Still, the latest Zaurus, the SL-C3200, does have a few nice features, including a 6GB hard drive, SD slot and 3.7-inch VGA touchscreen display.

IBM switching to Linux destops in Germany according to a Linux Forum 2006 presentation by their head of open source and Linux sales in Germany.

A man writes in asking for help in removing a file that just doesn't want to be deleted. (When I say you are deleted, you are deleted! - Scott)

Even if American voters are ready to use open source systems to cast their ballots -- meaning publicly available code under an open source license -- no vendor offers open source software and systems that are ready for voting.

[ED: Why not some effort to do it? Any vendor not wanting to play can be excluded. Remember, a republic is built on the belief you have some say in your vote. If that proves true, over throwing the current holders of power becomes the only option. Hence, this is too important an issue to say it's a nice concept. - HC]

As RedHat's community-supported Linux distribution, Fedora Core, amps up for its fifth release, the third test release has come out to give us an idea of what to expect when the final release hits in March. So, what's changed, what's new, and should you bother looking Fedora again? Full Review at http://linuxcult.com/story/03052006/fedora_core_5_test_3_rev...

  
"Windows Server System outperforms Linux on TCO, reliability, security, and indemnification." No, your Linux News editor in the Netherlands is not joking, it is really true. I read it on MS' "Get the Facts" page, so it has to be. On the other hand, Windows bla bla also outperforms Linux on indirect costs for marketing FUD and paying people to create studies, etc. They also outperform Linux in getting lawyers to do their bidding, fixing software bugs which tie customers to them, and money going to political parties in the US.

IBM has launched new open source development software enhancements for Web developers to use popular browser tools to build, test and run new voice applications. With the tools, developers can build serious speech recognition technology for everything from a cellphone to a TV.

Last month I wrote about buying a shiny new digital camera, and figuring out what computing platform to use for digital editing and archiving. Much to my shame, I actually tried Windows first. That didn't work very well. Then I thought, well hey, Macs are way cool and this kind of work is just what Macs excel at.

Well, I still don't own a Mac, as lovely and tempting as they are. Linux is working out great for my needs. Here's a quick outline.
