I saw this post on the Andrew Max blog the other day and made a note to talk about it here. In his original post titled "Yet another security alert". This is a good summary of the recent 0-day exploit found, or rather exposed by Oracle with code relating to views. I won't elaborate too much!
The second post is quite an interesting read and is titled "Too late" and is where Andrew discusses his thoughts about his previous post and also the decision to remove it and to then put it back again!. What I find interesting is the speed of the internet in disseminating information, not just about security bugs and spreading it to the world. He originally quoted Alex's page on the same bug, Alex then updated his page with info from Andrew, Andrew removed his post and then decided he should put it back. Once security bugs get out there it is very difficult to remove them or the information spread by them. The only cure is a patch from Oracle, for which we all have to wait until the next CPU, or could it be longer if you do not happen to be on one of the core platforms where the patches are actually released on the CPU day!.
