Two vulnerabilities have been discovered in Rails, a web application
framework written in Ruby. Both vulnerabilities affect Action Pack, which
handles the web requests for Rails.

Crafted requests to Action View, one of the components of Action Pack,

the result of an incomplete fix of CVE-2016-0752.
This bug was found by Jyoti Singh and Tobias Kraze from Makandra.

arbitrary ruby code.

Phenoelit.
