Ubuntu Security Notice 6838-1 - It was discovered that Ruby RDoc incorrectly parsed certain YAML files. If a user or automated system were tricked into parsing a specially crafted .rdoc_options file, a remote attacker could possibly use this issue to execute arbitrary code. It was discovered that the Ruby regex compiler incorrectly handled certain memory operations. A remote attacker could possibly use this issue to obtain sensitive memory contents.

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, ...

An issue was discovered in StringIO 3.0.1, as distributed in Ruby 3.0.x through 3.0.6 and 3.1.x through 3.1.4. The `ungetbyte` and `ungetc` methods on a StringIO can read past the end of a string, and a subsequent call to `StringIO.gets` may return the memory value. This vulnerability is not affected StringIO 3.0.3 and later, and Ruby 3.2.x and later. We recommend to update the StringIO gem to version 3.0.3 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 `stringio` 3.0.1.1 * For Ruby 3.1 users: Update to `stringio` 3.1.0.2 You can use `gem update stringio` to update it. If you are using bundler, please add `gem "stringio", ">= 3.0.1.2"` to your `Gemfile`.
