Title: RDoc: Remote Code Cxecution
Date: June 22, 2024
Bugs: #927565
ID: 202406-03
Synopsis
A vulnerability has been discovered in RDoc, which can lead to execution
of arbitrary code.
Background
RDoc produces HTML and command-line documentation for Ruby projects.
Affected packages
Package Vulnerable Unaffected
dev-ruby/rdoc < 6.6.3.1 >= 6.6.3.1
Description
A vulnerability has been discovered in RDoc. Please review the CVE
identifier referenced below for details.
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.
Resolution
All RDoc users should upgrade to the latest version:
emerge --sync
emerge --ask --oneshot --verbose “>=dev-ruby/rdoc-6.6.3.1”

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. We recommend to update the RDoc gem to version 6.6.3.1 or later. In order to ensure compatibility with bundled version in older Ruby series, you may update as follows instead: * For Ruby 3.0 users: Update to `rdoc` 6.3.4.1 * For Ruby 3.1 users: Update to `rdoc` 6.4.1.1 * For Ruby 3.2 users: Update to `rdoc` 6.5.1.1 You can use `gem update rdoc` to update it. If you are using bundler, please add `gem "rdoc", ">= 6.6.3.1"` to your `Gemfile`. Note: 6.3.4, 6.4.1, 6.5.1 and 6.6.3 have a incorrect fix. We recommend to upgrade 6.3.4.1, 6.4.1.1, ...
