Ruby on Rails receives the third security patch in less than a month

Ruby on Rails versions 3.0.20 and 2.3.16 fix an extremely critical remote code execution vulnerability

Developers of the Ruby on Rails Web development framework released versions 3.0.20 and 2.3.16 of the software on Monday in order to address a critical remote code execution vulnerability.

This is the third security update released in January for Ruby on Rails, an increasingly popular framework for developing Web applications using the Ruby programming language that was used to build websites like Hulu, GroupOn, GitHub, Scribd and others.

The Rails developers described the updates released Monday as "extremely critical" in a blog post and advised all users of the 3.0.x and 2.3.x Rails software branches to update immediately.

According to a corresponding security advisory, the newly released Rails versions address a vulnerability in the Rails JSON (JavaScript Object Notation) code that allows attackers to bypass authentication systems, inject arbitrary SQL (Structured Query Language) into an application's database, inject and execute arbitrary code or perform a denial-of-service (DoS) attack against an application.

The Rails developers pointed out that despite receiving this update, the Rails 3.0.x branch is no longer officially supported. "Please note that only the 2.3.x, 3.1.x and 3.2.x series are supported at present," they said in the advisory.

Users of Rails versions that are no longer supported were advised to upgrade as soon as possible to a newer, supported version, because the continued availability of security fixes for unsupported versions cannot be guaranteed. The newer 3.1.x and 3.2.x Rails branches are not affected by this vulnerability.

This latest Rails vulnerability is identified as CVE-2013-0333 and is different from CVE-2013-0156, a critical SQL injection vulnerability patched in the framework on Jan. 8. The Rails developers stressed that users of Rails 2.3 or 3.0 who previously installed the fix for CVE-2013-0156 are still required to install the new fix released this week.

A smarter way to print for busy small business owners, combining speedy printing with scanning and copying, making it easier to produce high quality documents and images at a touch of a button.

I've had a multifunction printer in the office going on 10 years now. It was a neat bit of kit back in the day -- print, copy, scan, fax -- when printing over WiFi felt a bit like magic. It’s seen better days though and an upgrade’s well overdue. This HP OfficeJet Pro 8730 looks like it ticks all the same boxes: print, copy, scan, and fax. (Really? Does anyone fax anything any more? I guess it's good to know the facility’s there, just in case.) Printing over WiFi is more-or- less standard these days.

I’d happily recommend this touchscreen laptop and Windows 10 as a great way to get serious work done at a desk or on the road.

Ultimately, I think the Windows 10 environment is excellent for me as it caters for so many different uses. The inclusion of the Xbox app is also great for when you need some downtime too!

For me, the Xbox Play Anywhere is a great new feature as it allows you to play your current Xbox games with higher resolutions and better graphics without forking out extra cash for another copy. Although available titles are still scarce, but I’m sure it will grow in time.
