RDoc produces HTML and command-line documentation for Ruby projects.
A vulnerability has been discovered in RDoc. Please review the CVE identifier referenced below for details.
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.
There is no known workaround at this time.
All RDoc users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-ruby/rdoc-6.6.3.1"
