Security

+ - Security exploit in Flash Player 9->

SadSoupDragon writes: Through general code-hackery, I have stumbled upon a nasty little bug in the most recent version of Flash Player (and every other version I've tried so far). This happened when I made a mistake in creating an in-memory SWF file, loaded it via flash.display.Loader, and extracted an asset from it as a Sound object. The sound plays, but the Flash Player audio engine keeps playing past the end of the sound — As a result, you actually hear a buffer overflow. The usual result is nasty bleeps and bloops (not unlike loading a Spectrum or C64 game) coming out of your speakers, which you can even record and save as a raw sound file to view the data. My browser usually crashes seconds later, yet another symptom of buffer-related security badness.

It's bad enough that a simple SWF file can bring the browser down, but the really scary thing is what could be done with the data accessed (I know that at least a SWF program could analyse the spectrum of this data and send it back to a server) — or worse still, if an in-memory SWF could be crafted in such a way that it overruns the buffer with executable code, as many of the worst software exploits do.

I've written a proof of concept which you can download the source of here, or try the compiled nastiness for yourself.

Bug

+ - Giant bug found - and it's not in Windows!

jd writes: "A giant 8' bug — actually a sea scorpion — has been found in London. The claws are the same size as a man's head. It has been dead for the past few million years, but it's the thought that counts. Being a fossil, it will be hard to clone, though it would make a superb monster in the next Jurassic Park movie."

+ - Pi Runner, a computer game that teaches Pi digits->

SadSoupDragon writes: "Pi Runner is a game that guides you through the digits of Pi, helping you to memorize obscene amounts and impress your geekiest of friends.

The game revolves around a pixelated crocodile running across a bridge made of Pi digits. Your task is to enter the digits of Pi on your numpad in time to fill in the bridge blocks, preventing the croc from falling to his doom.

So far the digit leader board ranges from 50 digits to 60,000... so make your mark!

The game is written in Flash 9, so will run fine on Linux, Windows and Macs."

SadSoupDragon writes: "There's a cute little math game online that helps you learn the digits of Pi. It has retro graphics and sound, and features a small crocodile walking along a bridge of Pi digits. It's your job to fill in those digits to save him from falling to his doom!

This is a great, fun way to memorise Pi. There's a competitive element too, as you can submit your score against other people. Can you beat Rain Man and Kim Peek?"
