A new threat for PHPBB users. Here’s a post from the PHP Security Blog.

“At Halloween 2005 I had disclosed a number of bugs in phpBB, including a remote code execution exploit through the signature_bbcode_uid variable. You will not find this vulnerability in the phpBB security tracker because it is phpBB project’s practise to blame their bugs on PHP and/or otherwise downplay them or hide them. Unfortunately there is now a public exploit for this vulnerability, which was released yesterday while most of us were celebrating christmas.”
