Apple fixed a recently discovered security hole in its iTunes Music Store which could be abused to download songs without anti-piracy protection.
The exploit was discovered by Jon Johansen - DVD Jon - which also cracked the security of DVDs years ago. He found out that the iTunes Music Store didn't add DRM (Digital Right Management) protection until a track had been bought and downloaded and he figured out a way to download songs for free.
Apple said that they fixed the problem and that users with old versions of iTunes will need to upgrade to iTunes v4.7.
