Now, Bugtraq contains a lot of people that are not that smart. Just for the record, there are also a lot of people there that are really smart though ;)
Anyway, I just got pointed to this vulnerability that was recently posted. It seems that in phpBB 1.4.4, there is a vulnerability in the image bbcode.
To explain my ... uhm ... panicked response for those not in the know: phpBB 1.4.4 is a very very very old version of phpBB, and has been unsupported since the release of phpBB 2.0. That was quite a while ago. phpBB 2.2 is already on it's way. Yes, it's THAT long ago.
