Summary
The nori gem 2.0.x before 2.0.2, 1.1.x before 1.1.4, and 1.0.x before 1.0.3 for Ruby does not properly restrict casts of string values, which allows remote attackers to conduct object-injection attacks and execute arbitrary code, or cause a denial of service (memory and CPU consumption) involving nested XML entity references, by leveraging Action Pack support for (1) YAML type conversion or (2) Symbol type conversion, a similar vulnerability to CVE-2013-0156.
