The crack gem 0.3.1 and earlier for Ruby does not properly restrict casts
of string values, which might allow remote attackers to conduct object-injection
attacks and execute arbitrary code, or cause a denial of service (memory and CPU
consumption) by leveraging Action Pack support for (1) YAML type conversion or (2)
Symbol type conversion, a similar vulnerability to CVE-2013-0156.
