As a Hop Studios client, we keep you informed about security updates that affect the software you use. This one is particularly important, as it concerns ExpressionEngine. In an nutshell:
- A small but serious security hole in ExpressionEngine has been discovered.
- Upgrading to 1.6.6 fixes this.
- Upgrading takes about an hour for a site with not much customization, and our standard hourly rate is $140.
- The license fee for the upgraded software is between free and $39.
Please let us know if you want to upgrade, and we will schedule you in; we expect many requests, and we’ll get to you as soon as possible in the order you respond.
Now, the details…
This email assumes you know what version site software you’re using.
In ExpressionEngine, this is the number at the bottom of every page of the control panel.
SECURITY UPDATES (ExpressionEngine)
The latest release of ExpressionEngine, 1.6.6, fixes a security hole. We have not been told exactly what security hole is patched. The developers say that it is a very minor issue that would only affect display of submitted text on the site, but that there’s is a very small chance that, with interactions with third-party software, it could be “quite serious.” Here is their blog post about it:
The last significant EE security problem was in 1.4.2, about three years ago. For a software product as large and powerful and widely used as EE, this is a tremendous safety record. Our confidence in EE is still very high. But we do recommend very strongly that you upgrade now to 1.6.6, no matter what earlier version of EE you are running.
GENERAL UPDATES (ExpressionEngine)
ExpressionEngine is now at version 1.6.6. We’ve been hoping for a 2.0 version to be released some time soon, but it has been pushed back several times. Meanwhile, new features keep showing up in the 1.6 branch, which is very stable and well-supported.
Here’s what’s new since 1.6.1, the last time we emailed you…
