You may not have updated Firefox. And you may be sorry when you are hit with the command line url shell command injection. Yeah, easy for me to say. If you use windows, you are in luck, you are not affected. This exploit can only happen to users on *nix platforms. The remedy is easy: update to Firefox 1.0.7 – and do it now. This exploit would allow a malicious link to execute arbitrary shell commands on the target host. Translation: the malicious person on the other side owns your box!
