CVE-2024-27281

An issue was discovered in RDoc 6.3.3 through 6.6.2, as distributed in Ruby
3.x through 3.3.0. When parsing .rdoc_options (used for configuration in
RDoc) as a YAML file, object injection and resultant remote code execution
are possible because there are no restrictions on the classes that can be
restored. (When loading the documentation cache, object injection and
resultant remote code execution are also possible if there were a crafted
cache.) The main fixed version is 6.6.3.1. For Ruby 3.0 users, a fixed
version is rdoc 6.3.4.1. For Ruby 3.1 users, a fixed version is rdoc
6.4.1.1. For Ruby 3.2 users, a fixed version is rdoc 6.5.1.1.
