We've released OSSIM 0.9.9 this week, release which was followed by a post to BugTraq regarding some XSS and SQL vulnerabilities present on OSSIM.
After having fixed those vulnerabilities we're now releasing:

• OSSIM Installer 1.0.4 (the recommended installation method)
• OSSIM Updater 1.0.4 (the recommended updating method for those running versions 1.0 - 1.0.3)
• OSSIM 0.9.9-3 Debian packages.
• OSSIM 0.9.9p1 for those who need source code.

We're proud to announce the soon-to-be-available 1.0.4 installer (versioning wise it could be 1.1 or even higher because of all of the changes but, well, we called it 1.0.4), both as a standalone ISO image as well as the updater.

We've been working very hard the past months on this, the updater has been a nightmare. It's much easier to make an installer than an updater...

For those wanting to try it out, just download update.pl and run it on a 1.0 - 1.0.3 installed image (should work with the images we've released inbetween on the forums too). Be warned tho, we're still on final testing phases and there might be some issues in there, any sort of testing will be more than welcome.

Basically the installer will backup all the databases and /etc/*, /usr/share/ossim*, install new packages (ossim 0.9.9), new deps (ossec, munin, fprobe) and tune some other things.
Anyway, as said, there are backups and it shouldn't be too hard to get it back working if something fails.

A few hints if you're going to try it out:

• Default values for most of questions are fine. If unsure just press enter.
• "auto" is the recommended way to go for new users, "expert" allows for a more fine grained setup.
• We experienced occassional hangs at the munin plugin setup step. Had to kill the following process on another terminal in order to continue with the installation process
• After everything has been installed you have to log in and upgrade the web part, it should work like a charm :-)
• Right now requires internet access; we'll publish an offline updater too of course

Check a sample installer output if you're curious.
