rubygems-pwn: A Vulnerability in RubyGems

If you've seen people saying to run  gem install rubygems-pwn  on Twitter (which I don't advise!), it's because it's a proof of concept for a vulnerabilty in RubyGems.

The rubygems-pwn project on GitHub has more information about it, but essentially you can push arbitrary Ruby code into gemspec parameters which will then be executed later on.

The vulnerability has been discussed in the rubygems repo where a fix has already been made but, hopefully, more general fixes should be made available soon. (If you want to see the direct example of a malicious gemspec, look here.)

The Rails developers have pushed out three new releases in tandem to fix the same security vulnerabilities. All three major branches have been covered. The vulnerabilities include:

• A way for attackers to render a view without first calling the corresponding action
