Today we received reports about certain sites being defaced. Investigation has shown that a worm which utilizes a vulnerability in phpBB is responsible for this.

PhpBB is a very popular software to use for internet boards/forums, so this affects a lot of sites. Therefore we are putting a Red Alert on it.

Currently there is no patch for this problem, only a work-around, which can be found here.
