The Joomla team just released versions 3.3.5, 3.2.6 and 2.5.26, patching security issues. The first one is an Remote File Include (RFI) vulnerability and the second one is a Denial of Service (DoS) vulnerability that affect all previous versions. If you are using Joomla, stop what you are doing and update it now!

What’s very exciting for us, me especially, is to see how our Zero Day response mechanism and the custom Virtual Hardening feature were able to work together to proactively protect users. This is an example of how to address the unknowns of website attacks. In short, this means that while any Joomla! user within our stack might be susceptible to the vulnerability, our technology was able to proactively stop a potential attack. This is what drives our team, this is why we build our technology. To learn more visit our Website Firewall product page.
