Ruby itself is mostly written in C, so a bug in Ruby itself could result in one of the previous security issues affecting Ruby. In addition, some Ruby gems include C extensions, either for performance reasons and/or because they need to interface with other libraries written in C. Ruby gems that include C extensions can also experience all these security issues.
