Description
active_support/core_ext/hash/conversions.rb in Ruby on Rails before 2.3.15, 3.0.x before 3.0.19, 3.1.x before 3.1.10, and 3.2.x before 3.2.11 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.
Affected configurations
• rubyonrails rails (>= 3.2.0 < 3.2.11)
• rubyonrails ruby on rails (< 2.3.15)
• rubyonrails ruby on rails (>= 3.0.0 < 3.0.19)
• rubyonrails ruby on rails (>= 3.1.0 < 3.1.10)
• debian debian linux 6.0
• debian debian linux 7.0
