Affected Packages

Package Vulnerable Unaffected ------------- ------------ ------------ dev-ruby/rdoc < 6.6.3.1 >= 6.6.3.1

Impact

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.

Workaround

There is no known workaround at this time.
