## Description

lib/active\_support/json/backends/yaml.rb in Ruby on Rails 2.3.x before
2.3.16 and 3.0.x before 3.0.20 does not properly convert JSON data to YAML
data for processing by a YAML parser, which allows remote attackers to
execute arbitrary code, conduct SQL injection attacks, or bypass
authentication via crafted data that triggers unsafe decoding, a different
vulnerability than CVE-2013-0156.
