Freedom Is Not Having To Ask Permission

Did you ever wonder why you're involved in the Free Software community? What makes you spend all this time on programming, patching, packaging, documenting, bug-fixing, and generally improving Free Software? What keeps you motivated?

Dave Neary of the GNOME project has a very good explanation: Freedom.

Free software taught me that I could learn and grow without someone telling me that I could.

Freedom is not having to ask permission.

Exploited Exploits

Someone on the security mailinglist Full-Disclosure has posted an interesting warning regarding proof-of-concept exploit code. It seems that multiple published exploits have been replaced with more malicious versions by unknown attackers.

The attackers replaced the shellcode in the demo exploits (which usually opens a root-shell) with more malicious versions like 'rm -rf /*'. As such shellcode usually consists of hex-encoded assembler instructions, most people don't have the slightest chance to understand it, and hence cannot verify what it really does. People who want to "just try out whether I'm vulnerable", might end up with a wiped hard drive (or worse).

The lesson (one of them, that is) we should learn here is to never execute any code we don't trust and/or fully understand.
