Gain root on OSX by holding down CTRL-C

I haven't posted a lot recently on exploits / vulnerabilities since so many lists are doing a good job of that, its pretty redundant for me to do the same. However, today I just had to post this one, as it made me chuckle as I realized that Alan's PowerBook is mine :P

Security Tracker reports that if you have a USB keyboard and you hold CTRL-C during a boot/reboot it will cause "init" to fail and give you a shell. Of course, you have to have physical access to the box, and should thus consider the box suspect anyways if someone can plug in a USB keyboard and then perform the CTRL-C deed... but thats not the point.

There is a fix for it. I suggest if you run OSX, that you go get it.

Update: There is an article about this by the original reporter with step-by-step screenshots on compromising the box if you are interested.

Good think that os/x has already asked me if I wanted to install the update and has :)
