The extlib gem 0.9.15 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.
